Big-Rig Friendly Campgrounds in Wyoming (Scored 1–10)
By Calvin Whitlock · Last updated July 7, 2026 · How we score
TL;DR: Wyoming is where grade, wind, and season join length capacity as the factors that decide whether a big rig fits — mountain passes gate the scenic parks, and I-80 crosswinds gate the interstate ones. These 10 campgrounds score highest on the Big-Rig Standard™ — a uniform 1–10 score built from eight data points. Western Hills Campground in Rawlins (9.5) and The Longhorn Ranch in Dubois (9.0) lead for 45-foot rigs; WYO Campground in Cheyenne (9.0) is the best I-80 overnight; Fort Caspar Campground in Casper (6.5) is the honest "workable with planning" pick with pull-throughs capped at 44 feet.
Every campground below is scored the same way, on the same eight data points, so a 9 here means the same thing as a 9 in Florida or Texas. For what each data point means and how the score is calculated, see Big-Rig Friendly, Defined.
How to read the score: 9.0–10 = rolls right in · 7.0–8.5 = big-rig comfortable · 5.0–6.5 = workable with planning. Cells marked (inferred) are derived from terrain and road data, not published specs — confirm with the park and help us sharpen them via the correction link at the bottom.
The 10 highest-scoring big-rig campgrounds in Wyoming
1. Western Hills Campground — Rawlins · Big-Rig Score: 9.5
The biggest big-rig inventory in the state: 120 pull-through sites and a published 80-foot max rig length, right on the I-80 corridor at Rawlins. This is the park you route through when you're crossing Wyoming with a 45-footer and a toad and don't want to unhitch — long pull-throughs built for multiple slide-outs, easy interstate access, and fuel at the Rawlins exits. The one Wyoming-specific caveat is the I-80 wind corridor itself: check WYDOT high-wind advisories before running this stretch with a high-profile rig.
| Data point | Value |
|---|---|
| Max rig length | 80 ft (published) |
| Turn radius / entry | Interstate-adjacent entry; long pull-through rows (inferred — adequate) |
| Pull-through vs. back-in | 120 pull-through sites plus back-in |
| Low-clearance warnings | None (inferred — open high-plains layout) |
| Fuel within 10 mi | Diesel + propane — Rawlins I-80 exits (inferred — strong corridor) |
| Grade on approach | Minimal at the park; I-80 wind advisories apply to the corridor (inferred — check WYDOT) |
| Overnight allowed | Yes — natural I-80 one-nighter |
| Surface / power | Gravel pads · 30/50-amp full hookups (confirm amp on site row) |
2500 Wagon Circle St, Rawlins, WY 82301 · (307) 324-2592
2. The Longhorn Ranch Lodge & RV Resort — Dubois · Big-Rig Score: 9.0
The best big-rig base for the Yellowstone/Grand Teton approach from the east. Published capacity runs to 85 feet with full hookups — the largest number on this page — on well-graveled pull-throughs spaced for privacy, three miles east of Dubois on US-26. The score docks half a point for what's around it, not what's in it: continuing west means Togwotee Pass (9,600 ft), a long sustained climb/descent that demands engine-brake discipline in a diesel pusher. Stage here, check conditions, then run the pass in daylight.
| Data point | Value |
|---|---|
| Max rig length | Up to 85 ft (published) |
| Turn radius / entry | Well-graveled pull-throughs, generous spacing (published) |
| Pull-through vs. back-in | Pull-through and back-in |
| Low-clearance warnings | None at the park (inferred — open ranch layout) |
| Fuel within 10 mi | Diesel + propane — Dubois, ~3 mi west; propane at the resort (published) |
| Grade on approach | Park approach on US-26 is moderate; Togwotee Pass westbound is a sustained mountain grade — plan it |
| Overnight allowed | Yes (seasonal — confirm season dates) |
| Surface / power | Gravel · 30/50-amp full hookups |
5810 US Highway 26, Dubois, WY 82513
3. WYO Campground & RV Park — Cheyenne · Big-Rig Score: 9.0
The best interstate overnight in Wyoming. Right off I-80 Exit 377 east of Cheyenne with 50 pull-throughs, 50 full hookups, and a published 75-foot max length — drive in, sleep, drive out, no backing. It's also the logical staging stop before (or after) the I-80 Laramie-to-Rawlins wind corridor, and its position near the I-80/I-25 junction makes it work for north–south traffic to Denver or Casper too.
| Data point | Value |
|---|---|
| Max rig length | 75 ft (published) |
| Turn radius / entry | Easy off I-80 Exit 377; pull-through rows (inferred — adequate) |
| Pull-through vs. back-in | 50 pull-through |
| Low-clearance warnings | None (inferred — open prairie layout) |
| Fuel within 10 mi | Diesel + propane — I-80/I-25 Cheyenne interchange network (inferred — strong) |
| Grade on approach | None — high-plains flat at the park |
| Overnight allowed | Yes — ideal one-night stop |
| Surface / power | Gravel · 50-amp full hookups |
4066 E I-80 Service Rd, Cheyenne, WY 82053 · (307) 547-2244
4. Deer Park Campground — Buffalo · Big-Rig Score: 8.5
A genuinely well-run park near the I-25/I-90 junction with 31 pull-throughs, a published 65-foot max, and premium pull-through sites up to 80 feet. Park-like setting, heated pool, and the small-town Buffalo location makes it the natural big-rig base for the Bighorns — without actually driving the Bighorns. Do not shortcut US-16 over Powder River Pass (9,666 ft) westbound with a 45-footer unless you've planned the grade; the interstate routing around is the big-rig move. Seasonal: open May 1 – September 30.
| Data point | Value |
|---|---|
| Max rig length | 65 ft standard · premium pull-throughs to 80 ft (published) |
| Turn radius / entry | Easy approach off US-16 near I-25/I-90 (inferred — adequate) |
| Pull-through vs. back-in | 31 pull-through + back-in (54 full hookups) |
| Low-clearance warnings | Mature trees in the park setting — watch high rooflines on interior loops (inferred — caution) |
| Fuel within 10 mi | Diesel + propane — Buffalo I-25/I-90 junction (inferred) |
| Grade on approach | None at the park; US-16 west over Powder River Pass is a major grade — route big rigs via interstate |
| Overnight allowed | Yes (open May 1 – Sep 30) |
| Surface / power | Gravel · 50-amp full hookups |
146 US Highway 16 E, Buffalo, WY 82834 · (307) 684-5722
5. Buffalo Bluff RV Park — Cody · Big-Rig Score: 8.5
Cody's purpose-built big-rig park — opened in 2021 and designed around large rigs from day one, with 43 big-rig sites, huge pull-throughs, 50-amp full hookups, and new shower suites on 13 acres overlooking town. Five minutes from downtown Cody and about 50 miles from Yellowstone's East Entrance, it's the right basecamp strategy for the biggest rigs: park here, run the Wapiti Valley and Sylvan Pass in the toad, keep the 45-footer on full hookups.
| Data point | Value |
|---|---|
| Max rig length | 45 ft+ (inferred — park is purpose-built for big rigs; 44 ft rigs report comfortable fits) |
| Turn radius / entry | Modern layout, wide interior lanes (inferred — 2021 build) |
| Pull-through vs. back-in | Large pull-throughs + back-in (43 big-rig sites) |
| Low-clearance warnings | None (inferred — open bluff-top layout) |
| Fuel within 10 mi | Diesel + propane — Cody, US-14/16/20 corridor (inferred) |
| Grade on approach | Short climb to the bluff off Belfry Hwy (inferred — moderate, paved) |
| Overnight allowed | Yes |
| Surface / power | Gravel · 50-amp full hookups |
137 Belfry Hwy, Cody, WY 82414 · (307) 578-7602
6. Sleeping Bear RV Park & Campground — Lander · Big-Rig Score: 8.0
The Wind River country pick. 19 pull-throughs running 45 to 70 feet, a published 65-foot max, and full-service sites on Main Street in Lander — a walkable small town that works as a multi-day base for Sinks Canyon and the Wind River Range. Approach from any direction is US-highway grade, not mountain-pass grade, which is worth a lot in this part of the state.
| Data point | Value |
|---|---|
| Max rig length | 65 ft (published; pull-throughs 45–70 ft) |
| Turn radius / entry | In-town Main Street entry; interior lanes adequate (inferred) |
| Pull-through vs. back-in | 19 pull-through + back-in (23 full-service sites) |
| Low-clearance warnings | Mature in-town trees — watch the roofline on interior loops (inferred — caution) |
| Fuel within 10 mi | Diesel + propane — Lander, US-287 corridor (inferred) |
| Grade on approach | Gentle — US-287/WY-789 river-valley approach |
| Overnight allowed | Yes |
| Surface / power | Gravel · 50-amp full hookups |
715 E Main St, Lander, WY 82520 · (307) 332-5159
7. Little America Wyoming RV Park — Little America (I-80 Exit 68) · Big-Rig Score: 8.0
A one-off: an RV park attached to the famous Little America travel-center complex on I-80 in southwest Wyoming. 42 sites with 25 ft × 60 ft pull-throughs, 30/50-amp full hookups, and — the score-mover — diesel, propane, food, and services on the property itself, not ten miles away. The 60-foot pads are the ceiling: a 45-foot pusher plus toad fits, but it's a calculated fit, not a sprawl. As a western-Wyoming I-80 overnight, nothing is easier.
| Data point | Value |
|---|---|
| Max rig length | ~45 ft + toad (25×60 ft pull-through pads, published) |
| Turn radius / entry | Travel-center scale entry — built for trucks |
| Pull-through vs. back-in | Pull-through (25×60) and back-in |
| Low-clearance warnings | None — commercial truck-stop clearances throughout |
| Fuel within 10 mi | On-site — diesel + propane at the Little America travel center |
| Grade on approach | None — flat off I-80 Exit 68 |
| Overnight allowed | Yes (seasonal — confirm dates) |
| Surface / power | Paved/gravel · 30/50-amp full hookups |
I-80 Exit 68, Little America, WY 82929 · (307) 875-2400
8. AB Camping & RV Park — Cheyenne · Big-Rig Score: 7.5
The Cheyenne alternative: 82 full-hookup pull-throughs (50/30-amp) minutes from the I-80/I-25 crossroads, with operator notes calling sites a fit for a 50-foot rig-plus-toad combined length. It scores below WYO because the published length ceiling is lower and the in-town approach on College Drive is a city street, not an interstate service road — but during Cheyenne Frontier Days (late July), having a second big-rig option in town is the difference between a site and a 100-mile detour. Book far ahead for that window.
| Data point | Value |
|---|---|
| Max rig length | ~50 ft combined (operator-stated; confirm for 45 ft + toad) |
| Turn radius / entry | City-street approach on W College Dr (inferred — manageable, not interstate-scale) |
| Pull-through vs. back-in | 82 full-hookup pull-through + 25 electric-only |
| Low-clearance warnings | None (inferred — open layout) |
| Fuel within 10 mi | Diesel + propane — Cheyenne I-80/I-25 network (inferred — strong) |
| Grade on approach | None — high-plains flat |
| Overnight allowed | Yes |
| Surface / power | Gravel · 50/30-amp full hookups |
1503 W College Dr, Cheyenne, WY 82007 · (307) 634-7035
9. Devils Tower / Black Hills KOA Journey — Devils Tower · Big-Rig Score: 7.0
You stay here for the view — the Tower fills the windshield from the campground, which sits just outside the monument gate. Pull-throughs with 50-amp are available, and length claims in published listings range from 65 feet up to 100; treat the low number as the planning number and request the longest pull-through row when booking. The WY-24/WY-110 approach is two-lane rural highway with moderate rolling grade, and interior lanes at an older destination campground are tighter than a purpose-built big-rig park. Seasonal (roughly May–September); the monument's own campground is not a big-rig option.
| Data point | Value |
|---|---|
| Max rig length | 65 ft planning figure (published listings conflict, 65–100 ft — confirm site row when booking) |
| Turn radius / entry | Two-lane WY-24/WY-110 approach; tighter interior lanes (inferred — caution) |
| Pull-through vs. back-in | Pull-through (50-amp) and back-in |
| Low-clearance warnings | Mature cottonwoods on interior loops (inferred — watch 13'6" roofline) |
| Fuel within 10 mi | Limited — nearest full diesel/propane in Hulett or Moorcroft; top off on I-90 (inferred — plan ahead) |
| Grade on approach | Moderate rolling grade on WY-24 (inferred) |
| Overnight allowed | Yes (seasonal, ~May–Sep) |
| Surface / power | Gravel · 50-amp available |
60 Highway 110, Devils Tower, WY 82714 · (307) 467-5395
10. Fort Caspar Campground — Casper · Big-Rig Score: 6.5
The honest one — workable with planning. Casper's riverside campground has 86 full-hookup, big-rig-friendly sites with 20/30/50-amp, but only 14 pull-throughs, and those cap at 44 feet — which means a 45-foot pusher is either backing in or negotiating for the longest pull-through row. The setting (North Platte River, next to the Fort Caspar historic site) and year-round operation earn it the slot over splashier seasonal parks. Call ahead, state your exact length with toad, and request a specific site.
| Data point | Value |
|---|---|
| Max rig length | 44 ft on pull-throughs (published); longer rigs back-in only — confirm |
| Turn radius / entry | Riverside layout; site-specific — request assignment by rig length (inferred — caution) |
| Pull-through vs. back-in | 14 pull-through (≤44 ft) · remainder back-in (86 FHU total) |
| Low-clearance warnings | Riverside cottonwoods on some loops (inferred — watch the roofline) |
| Fuel within 10 mi | Diesel + propane — Casper, I-25/US-20 network (inferred) |
| Grade on approach | None — river-flat approach |
| Overnight allowed | Yes — open year-round (confirm winter services) |
| Surface / power | Gravel · 20/30/50-amp full hookups |
4205 Fort Caspar Rd, Casper, WY 82604
How we scored these
Every campground is scored on the Big-Rig Standard™: a weighted 1–10 composite of length capacity (30%), site type & power (20%), maneuverability (20%), clearance & grade (15%), fuel & services within 10 mi (10%), and stay flexibility (5%).
Wyoming is the opposite of a flat state: grade, wind, and season carry real weight here. Mountain passes (Togwotee, Powder River, Sylvan) sit between the interstates and the scenic parks, the I-80 corridor between Laramie and Rawlins is a documented high-wind zone for high-profile vehicles, and roughly half the parks on this page close for winter. Site dimensions, amp service, pull-through counts, and max rig lengths are sourced from park listings (July 2026). Fuel proximity, clearance, and grade are inferred from terrain and the surrounding road network and are marked (inferred) in each table. If you've stayed at one of these and the data's off, the Submit a correction link below feeds straight into the next update.
How this list was made: We screened Wyoming RV parks for published big-rig specs (max rig length, pull-through count and dimensions, 50-amp full hookups), scored each on the six-factor Big-Rig Standard™, and cross-checked maneuvering and approach notes against guest reviews and directory listings on Campendium, The Dyrt, Good Sam, and AllStays. Research and drafting were AI-assisted and human-reviewed. We have not personally stayed at every park on this list — where a score rests on inference rather than a published spec or a guest report, the cell is marked (inferred), and safety-relevant fields (clearance, grade) are kept conservative. No park paid for placement or for its score.

Frequently asked questions
What is the most big-rig friendly campground in Wyoming?
By the Big-Rig Standard™, Western Hills Campground in Rawlins (9.5) — 120 pull-through sites, a published 80-foot max rig length, and direct I-80 access make it the one Wyoming park where any rig on the road rolls right in.
What is the best I-80 overnight stop in Wyoming for a big rig?
WYO Campground in Cheyenne (9.0) at the east end — 50 pull-throughs, 75-foot max, right off Exit 377 — and Little America (8.0) at Exit 68 in the west, where diesel and propane are on the property. Between them, Western Hills in Rawlins (9.5) covers the middle of the state.
Can a 45-foot motorhome get to Yellowstone's East Entrance from Cody?
The road itself (US-14/16/20 through Wapiti Valley, then Sylvan Pass at 8,530 ft) is maintained for large vehicles, but Sylvan Pass is a real mountain grade and Yellowstone's interior campgrounds mostly cap well under 45 feet. The proven big-rig strategy is to base at Buffalo Bluff RV Park in Cody (8.5) and drive the park in a toad.
Is I-80 across Wyoming dangerous for big rigs?
It's routine when it's calm and genuinely hazardous in wind events — the Laramie-to-Rawlins segment posts high-wind closures for light, high-profile vehicles multiple times a year, and that description fits a Class A. Check WYDOT road conditions before each driving day, and stage at Cheyenne, Rawlins, or Little America rather than pushing through an advisory.
Are Wyoming RV parks open year-round for big rigs?
Mostly no — the majority of the parks on this page run roughly May through September (Deer Park publishes May 1–Sep 30). For winter or shoulder-season travel, plan around the year-round interstate-corridor parks like Fort Caspar Campground in Casper (6.5) and the Cheyenne parks, and confirm water service before arrival because hard freezes shut down hookups.
