Best time to visit Hot Springs State Park
Late May through September is the most comfortable window for RV travel, with warm days, long daylight, and full access to the Bighorn River paths and bison loop. July and August are peak months and the State Bath House and town can be busy on weekends. Shoulder seasons in May and September offer cooler weather, fewer crowds, and pleasant soaking conditions. Winter visits are possible since the park stays open year-round, but expect snow, ice, and limited services.

How to get to Hot Springs State Park
Thermopolis sits on US Highway 20 and Wyoming Highway 789, roughly 84 miles south of Cody and about 130 miles east of Jackson via Togwotee Pass. RV drivers heading north from Casper face an approximately 130-mile drive on US 20/26, while those coming through Wind River Canyon between Shoshoni and Thermopolis should be aware of the three short tunnels on US 20, which have posted height clearances that taller rigs must verify in advance. Mountain grades on Togwotee Pass and on routes from Cody can be steep, so check brakes and weight before departure. The closest commercial airports for fly-and-rent travelers are Worland (WRL), Riverton (RIW), Cody (COD), and Billings (BIL) in Montana.
