The Greatest RV Road Trip That Most People Under-Plan

The Wyoming national park corridor — Yellowstone in the north, Grand Teton immediately south, and the surrounding Jackson Hole valley — draws millions of visitors each year, many of them in RVs. It's one of the most spectacular driving routes in North America: thermal geysers, wolf packs crossing open valleys, bison jams that bring traffic to a stop for 20 minutes, and mountain vistas that make every photograph feel inadequate.

It's also one of the most logistically demanding RV routes in the country. Sites inside the national parks fill up 6 months in advance. Mountain roads have vehicle length restrictions that strand unprepared RVers. Weather can change from 70°F sunshine to snow in the same afternoon in July. And the region's popularity means that the window between "still great" and "overwhelming crowds" is narrow.

This guide covers everything you need to plan this route well.

The Core Route: 7–14 Days

The classic Wyoming RV circuit runs roughly as follows:

1. Cody, Wyoming: Eastern gateway, 1–2 nights
2. Yellowstone East Entrance: 2–3 nights in or near the park
3. Yellowstone interior (Norris, Madison, Old Faithful): 2–3 nights
4. Yellowstone North Entrance / Gardiner: 1–2 nights
5. Grand Teton / Jackson Hole: 2–3 nights
6. Jackson, Wyoming: 1–2 nights

Total driving: approximately 600–800 miles including in-park movement. Total time: 7–14 days depending on pace. This is not a trip to rush — every section rewards slow travel.

Cody: The Underrated Eastern Gateway

Most RVers approach Yellowstone from the south (Jackson) or west (West Yellowstone, Montana). The eastern approach through Cody on US-14/16/20 — the Buffalo Bill Cody Scenic Byway — is one of the most spectacular drives in the American West and one of the least-crowded Yellowstone approaches.

Cody itself is a genuinely interesting small city with the Buffalo Bill Center of the West (one of the best Western museums in the country), rodeo performances every night in summer, and excellent RV parks with full hookups that serve as the region's best staging ground.

Big-rig access note: The Buffalo Bill Cody Scenic Byway (US-14/16/20) from Cody to Yellowstone's East Entrance has no vehicle length restrictions, unlike some routes within the park. Class A coaches and fifth wheels up to 40 feet have no issues. The road through Wapiti Valley is spectacular and passes several high-quality campgrounds with full hookups.

Inside Yellowstone: Campground Reality Check

Yellowstone has 12 campgrounds with roughly 2,000 sites. In summer (mid-June through mid-August), every single site is occupied by 9 AM if it wasn't pre-booked, and reservation sites sell out within minutes of opening 6 months in advance. This is not hyperbole — it is the daily reality of Yellowstone camping.

Reservation campgrounds (book 6 months in advance)

• Madison Campground: Central location, 278 sites, maximum rig length 40 feet (most pull-throughs), no hookups. Excellent base for Norris geyser basin, Firehole River, and Old Faithful. The best all-around campground in the park for RVers.
• Canyon Village Campground: 271 sites, near the Grand Canyon of the Yellowstone, maximum 40 feet. Very popular with families.
• Bridge Bay Campground: Near Yellowstone Lake, 432 sites, maximum 40 feet. Beautiful water views, marina access.

First-come, first-served campgrounds (arrive by 8 AM)

• Norris Campground: 100 sites, 30 feet maximum. Quieter atmosphere, near the most thermally active geyser basin in the park.
• Slough Creek Campground: 16 sites, small rigs only (under 30 feet). The best wolf-watching campground in the park — in the Lamar Valley where the Druid Peak Pack's territory historically covered.

The practical reality for RVers

If you can't get a reservation inside the park, you're not stuck. The communities surrounding Yellowstone — Gardiner (north), West Yellowstone (west), Cooke City (northeast), and Wapiti/Cody (east) — all have private campgrounds with full hookups within 30–60 minutes of the park entrance. Many full-time RVers prefer these: better amenities, no vehicle length restrictions, and the same park access via a short drive.

Yellowstone Must-See Stops

Old Faithful and the Upper Geyser Basin

Old Faithful erupts roughly every 91 minutes and is the most-visited spot in the park. The crowds are real but worth it for a first visit. More interesting to experienced visitors is the 5-mile boardwalk through the Upper Geyser Basin, which contains more geysers than anywhere else on earth. Morning light (6–8 AM) is the best time — crowds are thin and the steam is dramatic.

Grand Prismatic Spring

The largest hot spring in the US and one of the most visually stunning natural features in the country. The famous overhead view (the multicolored rings you've seen in every Yellowstone photo) is best from the Grand Prismatic Spring Overlook Trail — a short hike above the Midway Geyser Basin. The overlook requires a 1.5-mile roundtrip hike. Do it.

Lamar Valley: America's Serengeti

The Lamar Valley in Yellowstone's northeast corner is the best place in the lower 48 states to see wolves in the wild. Gray wolves were reintroduced to Yellowstone in 1995 and the population is now over 100 animals. Dawn and dusk in the Lamar Valley, with binoculars or a spotting scope, almost guarantee wildlife sightings: bison, pronghorn, coyotes, and — with luck and patience — wolves.

Driving note: The Northeast Entrance Road (US-212 from Cooke City) is the most scenic in the park but has sections with lower clearance and tighter curves. Verify current road advisories at the park entrance. Most Class C motorhomes and travel trailers under 30 feet do fine. Longer coaches should take the alternative route through Gardner.

Grand Teton: The Rig-Fit Reality

Grand Teton National Park sits immediately south of Yellowstone and offers some of the most dramatic mountain scenery in North America — the Teton Range rises 7,000 feet from the valley floor with no foothills to obscure the view. From an RV campground, you're literally parked with the mountains as your backdrop.

Campgrounds in Grand Teton

• Colter Bay Village RV Park: The only campground in Grand Teton with full hookups (electric/water). 112 sites, maximum 40 feet. On Jackson Lake. Reservations required and taken 6 months ahead. This is the crown jewel for RVers in the park.
• Signal Mountain Campground: No hookups, 86 sites, 30 feet maximum. Stunning Teton views, lakeside location. First-come only — arrive before 7 AM in summer.
• Gros Ventre Campground: 350 sites, largest in the park, maximum 45 feet in some loops. No hookups but accepts larger rigs. More likely to have availability than Signal Mountain.

Jackson Hole: What's Outside the Park

The town of Jackson is one of the most expensive small towns in America (median home price over $2M) but the surrounding valley has several well-equipped RV parks that serve as practical bases. Parks in the Gros Ventre Road / Kelly area provide Teton views comparable to inside-park sites at lower nightly rates and with hookups — the practical choice for a multi-night stay if inside-park reservations weren't secured.

The Northern Loop: Gardiner to Sheridan

Once you've done Yellowstone and Teton, the drive north from Gardiner to Sheridan through Paradise Valley and over the Beartooth Highway is a bucket-list route in its own right. The Beartooth Highway (US-212 from Cooke City to Red Lodge, Montana) is often called the most beautiful road in the United States. The route climbs to 10,947 feet with sweeping tundra plateaus and 60-mile views.

Big-rig warning: The Beartooth Highway is NOT suitable for large RVs. The switchbacks above Red Lodge are extreme. If you're in a Class A over 28 feet or a fifth wheel over 30 feet, take the alternative route through Livingston and Billings to Sheridan. Smaller Class B, Class C, or short travel trailers can do the Beartooth as an extraordinary experience — just go slowly.

Wind River Country: The Hidden Wyoming

If you have an extra week and want to escape the national park crowds entirely, the Wind River Range south of Yellowstone is one of the most beautiful and accessible wilderness areas in the country — and almost entirely unknown outside of backpacking circles. The towns of Dubois, Pinedale, Lander, and Riverton all have good RV parks within an hour of the wilderness.

Wind River is a legitimate base for full-time RVers who want Wyoming's scenery without Yellowstone's logistics. Monthly rates at parks in Lander and Riverton run $400–$700/month — some of the best long-stay value in the Rocky Mountain West.

Trip Timing: When to Go

Period	Conditions	Verdict
May / early June	Snow possible, some roads closed, low crowds	Good for experienced RVers willing to be flexible on routes
Late June–July	Peak crowds, maximum fees, all roads open	Best access and weather, worst crowds. Book sites in January.
August	High crowds, afternoon thunderstorms, wildlife active	Great for wildlife; book the same as July
September	Elk rut, less crowded, cooler nights, fall colors starting	Best overall month. Thinner crowds, dramatic elk rut in the Tetons, excellent light.
October	Most campgrounds close, cold nights, stunning fall colors	Limited options but extraordinary scenery for self-contained rigs

Big-Rig Summary for Wyoming

• US-14/16/20 (Cody to East Entrance): No restrictions, excellent for all sizes
• Yellowstone main loop roads: 40 feet maximum for most campgrounds, 45 feet some
• Beartooth Highway: 28 feet maximum recommended (some sources say no RVs over 24 feet on tightest section)
• Grand Teton: 40 feet at Colter Bay with hookups; 45 feet at Gros Ventre
• Jackson Hole valley roads: Flat, wide, no restrictions
