An example of what RVmapper builds — published so you can read a complete itinerary without signing up.
A classic week-long route from the Front Range up through northern Colorado, across the Wyoming wide-open, and into the Greater Yellowstone Ecosystem via Grand Teton. Drive days are kept under 4 hours so you arrive at camp with time to set up, walk the dog, and actually enjoy the place. Mileage is honest — the distance is short on paper but the elevation changes (Cherry Creek at 5,500 ft to Togwotee Pass at 9,658 ft) put real strain on the rig, so the itinerary builds in slower climbing days and overnight stops with shore power for the AC unit you will absolutely run by 4 PM in July.
The piece RVmapper does that other planners do not — pull your campground memberships into the route and show where each one actually applies.

Worth scanning before booking — Passport America is geared toward shoulder-season stays
Aurora, CO · 23 miles from Denver · 30 min
A 4,000-acre state park 25 minutes southeast of downtown Denver. Use this as a shake-down stop the night before the long drive — top off water, test the levelers, run the generator under load. The campground has 135 RV-friendly sites with 30/50A electric and water; sites #1–32 are in the loop with the most shade and the easiest backing.
Steamboat Springs, CO · 162 miles from Cherry Creek · 3 hr 45 min
First real driving day — 160 miles up I-70 and US-40 through Berthoud Pass (11,307 ft). Plan to climb in the morning before afternoon thermals build, and use lower gears on the descent into Granby. The Steamboat KOA sits along the Yampa River with full hookups; sites along the river fill first so book ahead in summer.
Manila, UT · 210 miles from Steamboat Springs · 4 hr 15 min
Crossing the Wyoming-Utah line takes you through some of the emptiest landscape on the route — bring a downloaded podcast, fuel up in Rock Springs (last reliable diesel for 80 miles westbound). Flaming Gorge itself is a 91-mile-long reservoir cut into red rock. Stay at Lucerne Valley Campground on the lake — 147 sites, half with electric, level paved pads.
Moose, WY · 180 miles from Flaming Gorge · 3 hr 45 min
First view of the Tetons from the south on US-26 is a moment people remember. Gros Ventre is the largest campground in Grand Teton with 300 sites, the only one that takes RVs up to 45 feet, and the only one with electric hookups (a subset of sites). It is first-come-first-served for non-electric sites and reservation-only for the electric loop — book the electric loop in March if you can.
Grand Teton NP, WY
Rest day from driving — leave the rig at Gros Ventre and explore by tow vehicle or shuttle. Mormon Row at sunrise is the most photographed spot in the Tetons (the T.A. Moulton Barn). Schwabacher Landing is a half-mile flat walk to a beaver pond with the Tetons reflected in still water. Both are within 15 minutes of camp.
West Yellowstone, MT · 115 miles from Gros Ventre · 3 hr 30 min (allow 6 hours with stops)
From Gros Ventre, head north on US-191 through the John D. Rockefeller Memorial Parkway and into Yellowstone via the South Entrance. Drive time looks short (~110 miles) but plan a full day — every wildlife sighting is a 20-minute traffic stop, and you will want to pull over for at least the Old Faithful area before exiting through West. Grizzly RV Park is the closest full-hookup option to the West Entrance, walkable to the IMAX and the town's restaurants.
Yellowstone NP, WY/MT
Final day, and a full one. The Lower Loop (Old Faithful, Grand Prismatic, Midway Geyser Basin, Fountain Paint Pot) is the can't-miss circuit if you only get one day. Start at 6:30 AM to beat both the heat and the tour buses — Grand Prismatic at 8 AM in low light is far more dramatic than at noon. Park the RV at Madison Junction and use the visitor lot loops; full-size RVs do not fit at most pull-offs on the loop road.
