Thermopolis — Mineral Terraces, the Free Bathhouse & the Wind River Canyon
Three unhurried days built around the largest mineral hot spring on earth, in the ranch town of Thermopolis on the eastern flank of the Wind River country. Day one settles into Hot Springs State Park, where mineral-laden water builds glowing travertine terraces above the Bighorn River and pours into a free state bathhouse — a soak the Shoshone and Arapaho ceded to the public on the condition it always remain free. Day two mixes the town's playful side, the waterslides and soaking pools of the Star Plunge, with the great scenic set piece of the region, the drive down through the layered walls of the Wind River Canyon. Day three visits the ancient rock art of Legend Rock, wanders the little town, and turns for home. It is a slow, soaking, wide-open weekend of warm water, red rock, and big Wyoming sky.

Hot Springs State Park Mineral Terraces
★ 4.7The centerpiece of Thermopolis is Hot Springs State Park, where mineral water surfaces at around 128 degrees and, over centuries, has built a dramatic staircase of travertine terraces that spill toward the Bighorn River in bands of white, orange, and green. Boardwalks lead across the steaming, rainbow-colored formations to the Rainbow Terrace and the swinging suspension footbridge over the river, where the hot water pours in visible cascades. It is a genuinely otherworldly landscape and completely free to wander. Take your time on the boardwalks — the mineral deposits shift and grow year by year — and watch for the small herd of bison the state maintains on the pasture at the park's edge.

One Eyed Buffalo Brewing / Pumpernick's, Thermopolis
Downtown Thermopolis has a couple of easygoing spots for lunch a few minutes from the park — a local brewpub pouring its own beer alongside burgers and pub plates, and a long-running family cafe known for sandwiches and pie. Either makes a relaxed midday stop after a morning on the terraces, with the unhurried pace of a small Wyoming ranch town. Fuel up before an afternoon soak; the mineral water is famously relaxing and you'll want an easy evening afterward.

State Bath House (Free Soak)
★ 4.7Inside Hot Springs State Park stands the State Bath House, where anyone can soak in the mineral water free of charge — a public gift written into the 1896 treaty by which the Shoshone and Arapaho ceded the springs to the United States, on the enduring condition that a portion always remain free to all people. Indoor and outdoor soaking pools are kept at a soothing 104 degrees, and free twenty-minute soaks are offered during open hours (bring your own suit and towel). It is a wonderfully old-fashioned, unpretentious experience and the perfect low-key close to the first afternoon. Ease in slowly, hydrate well afterward, and let the day's drive melt away in the warm mineral water.

Thermopolis Lodging (Night 1)
Thermopolis has a good range of lodging, much of it clustered in and around Hot Springs State Park. Several hotels sit right on the park grounds with their own mineral soaking pools, letting you step from your room straight into the warm water — the most fitting choice for a hot-springs weekend. Downtown also has simple, well-kept motels a short walk from restaurants. Book a park-side property with a mineral pool if you can; an evening and morning soak with the terraces glowing across the river is the heart of the whole trip. Reserve ahead in summer.

Star Plunge
★ 4.5The Star Plunge is Thermopolis's beloved, gloriously retro mineral waterpark, in operation since 1900 within Hot Springs State Park. Alongside big indoor and outdoor mineral pools, it offers waterslides, a diving board, a hot 'vapor cave' steam room carved into the hillside, and the towering outdoor 'Blue Thunder' slide — all fed by the same warm mineral water as the free bathhouse. It is cheerfully old-fashioned and enormously fun for a relaxed morning, especially for families. There's a modest admission fee; a neighboring plunge offers a slightly quieter, adults-leaning alternative if you'd rather just soak.

Black Bear Cafe, Thermopolis
A homey main-street cafe is the natural place for a hearty midday meal before the afternoon's scenic drive — big breakfasts served all day, generous sandwiches, and homemade pie in an unfussy small-town room. Thermopolis is ranch country, and the portions and pace reflect it. It is an easy, filling stop to set you up for the canyon.

Wind River Canyon Scenic Drive
★ 4.9South of Thermopolis, U.S. 20 threads the Wind River Canyon, one of the most spectacular scenic drives in Wyoming, where the river has cut a gorge more than 2,000 feet deep through the flank of the Owl Creek Mountains. The road follows the water past sheer, banded walls of rock that descend through hundreds of millions of years of geologic time, marked by roadside signs naming each ancient formation as you pass it. At the 'Wedding of the Waters' the river famously changes names — the Wind River above, the Bighorn below. Drive it slowly, stop at the pullouts to crane up at the canyon walls, and watch for bighorn sheep on the cliffs and rafters running the whitewater below. Turn around at Boysen Reservoir at the canyon's far end for the return.

Thermopolis Lodging (Night 2)
A second night back at your Thermopolis base, ideally the same park-side hotel with a mineral pool for one more evening soak after the canyon drive. If you'd like a change of scene for dinner, the town's brewpub or steakhouse offer relaxed evening options within a few minutes' walk or drive. Keep the pace easy — an early evening soak, a quiet meal, and a good rest set you up for the petroglyphs and the long drive home tomorrow.

Legend Rock Petroglyph Site
★ 4.7Northwest of Thermopolis, the Legend Rock petroglyph site preserves one of the most significant concentrations of rock art in the northern Rockies — hundreds of figures pecked into a long sandstone cliff along a quiet creek, some more than 10,000 years old. The panels include the distinctive broad-shouldered, hollow-bodied 'Dinwoody' figures sacred to the Shoshone, along with animals, hunters, and spirit beings. A short interpretive trail runs the base of the cliff; the site is managed by the state, and it is worth stopping first at the state park's cultural center in town to confirm access and pick up the interpretive guide. It is a hushed, contemplative morning walking beneath millennia of human imagery in an utterly remote setting. Tread lightly and never touch the panels.

Storyteller Steakhouse / Downtown Thermopolis
★ 4.8Back in town, a relaxed downtown restaurant makes the right final meal before the long drive home — a hearty Wyoming steak, a burger, or a sandwich in an unhurried small-town room. Thermopolis's compact main street is easy to stroll after lunch, with a few shops and the Hot Springs County Museum if you have time. Enjoy a slow last meal and top off the tank; the return route is long and open.

Wyoming Dinosaur Center & Town Stroll
★ 4.7If there's time before turning for home, the Wyoming Dinosaur Center on the edge of town is a genuinely impressive stop — mounted skeletons, an active dig site on the surrounding hills, and a collection built from the rich fossil beds of the region. Otherwise, one more slow loop of Hot Springs State Park, a final look at the steaming terraces, and perhaps a last free soak make a fitting farewell to Thermopolis. It is an easy, unhurried close to the weekend before the long, scenic drive back west to Jackson.
