Hot Springs State Park, Thermopolis: A Wyoming RV Guide

Wyoming State Parks describes more than 1.8 million gallons flowing over the mineral terrace every 24 hours at a constant 128 degrees Fahrenheit, building the colorful terraces that step down toward the Bighorn River. The free State Bath House holds its water at about 104 degrees and stays open year-round, closing only on Thanksgiving and Christmas Day.

Beyond the bath house, the park strings together easy attractions: the swinging footbridge — a suspension bridge across the Bighorn River — frames views of the river and the mineral terrace, and the grounds invite an unhurried walk among the steaming travertine.

Because Thermopolis sits along central Wyoming's highways, the park makes a convenient and free stop on a longer Wyoming RV route. Confirm current State Bath House hours and any seasonal notes on the official Wyoming State Parks page before you arrive.
