Thermopolis — The Wyoming Dinosaur Center, Hot Springs Terraces & Legend Rock
Three hours northeast of Jackson, where the Wind River bursts out of its canyon and becomes the Bighorn, the town of Thermopolis sits atop the largest mineral hot spring in the world and beside some of the richest active dinosaur dig sites in North America. Day one is deep time made vivid: the Wyoming Dinosaur Center's world-class collection of mounted skeletons, its working preparation lab, and — in season — an actual visit to the dig sites on the ridges above town, where Jurassic bones are still coming out of the ground. Day two turns to the earth's living heat and the region's first people: the travertine terraces and free public bathhouse of Hot Springs State Park, and the ancient petroglyphs pecked into the sandstone at Legend Rock, some of them thousands of years old. An overnight in Thermopolis stitches the two together.

Wyoming Dinosaur Center
★ 4.7One of the few dinosaur museums in the world with its own active excavation sites within sight of the building, the Wyoming Dinosaur Center displays more than 30 mounted skeletons across a spacious gallery — among them a 106-foot Supersaurus, an Archaeopteryx cast (one of very few in North America), Triceratops, and a Tyrannosaurus. Through glass you can watch technicians in the preparation lab cleaning bones freshly out of the ground with dental picks and air scribes. The exhibits trace the sweep of life from the Cambrian through the age of dinosaurs, drawing heavily on fossils recovered from the surrounding Morrison Formation ridges. Plan a couple of hours; the collection is far larger and more serious than a town of 3,000 would suggest.

A cheerful downtown Thermopolis cafe serving sandwiches, salads, soups, and espresso — a light, welcome midday break between the dinosaur museum and the afternoon dig-site tour. It is one of the town's more contemporary spots, popular with locals and travelers alike. An easy place to regroup before heading up to the ridges.

Black Bear Cafe, Thermopolis (dinner)
A long-running, homey Thermopolis diner known for big breakfasts and comforting American dinners, a fitting end to a day in the field. Expect hearty portions of the kind that suit a ranching-and-mining town, served without pretense. It is a short drive or walk from most of the town's lodging, making it an easy final stop before settling in for the night.

Best Western Plus Plaza Hotel, Thermopolis
Set within Hot Springs State Park itself, the Best Western Plaza Hotel is a historic property with its own mineral hot pool fed by the springs — an ideal base that puts you within walking distance of the travertine terraces you'll explore in the morning. Rooms are comfortable and the location is unbeatable for this itinerary. Several other options cluster nearby, including the Days Inn and locally owned motels along the park approach; book ahead in summer, as the town's room stock is limited.

Hot Springs State Park — Terraces & Big Spring
★ 4.7Hot Springs State Park protects the Big Spring, which the world's guidebooks rank among the largest mineral hot springs on the planet, discharging some 8,000 gallons a minute at 128 degrees. Over millennia the mineral-laden water has built spectacular terraces of orange, brown, and cream travertine that cascade toward the Bighorn River, crossed by a walkable swinging suspension bridge with a fine view. Under an 1896 treaty with the Eastern Shoshone and Northern Arapaho, part of the springs was set aside for free public use forever — the reason the park maintains a free State Bath House where visitors can soak in the mineral waters at no charge. Walk the boardwalks along the terraces early, before the day warms, and watch for the park's small herd of bison on the far side.

The Safari Club at the Plaza Hotel (lunch)
The dining room at the historic Plaza Hotel within the state park serves a solid sit-down lunch of American fare in a setting decorated in old-lodge style. It is the most convenient option right in the park after a morning on the terraces, and a comfortable place to fuel up before the drive out to Legend Rock. Sit near the windows for views over the park grounds.

Legend Rock Petroglyph Site
★ 4.7Northwest of Thermopolis, a sandstone cliff along Cottonwood Creek carries one of the most important rock-art sites in the Northern Plains: more than 300 petroglyphs pecked and incised across nearly 100 panels, some dated to more than 10,000 years old and many belonging to the distinctive Dinwoody tradition of the region. The imagery includes large anthropomorphic 'water ghost beings,' hunters, and animals, sacred to the Eastern Shoshone and other tribes who regard the site as a place of power. A short trail runs beneath the cliff past the panels; a small interpretive shelter explains the traditions and the conservation effort. Treat the site with respect — do not touch the panels, as skin oils accelerate their decay — and check ahead, since access is sometimes managed through the state park office in town.
