Wyoming State Parks
Hot Springs State Park from across the Bighorn River
Wyoming has some beautiful state parks, most of them around man-made lakes spread across this normally dry countryside. Bear River State Park is the only state park in Wyoming that isn't based mostly on the enjoyment of water sports, although Hot Springs State Park in Thermopolis challenges that comment (Hot Springs is based around the largest mineral hot springs on Earth). However, at my age, spending a few days lounging around in 104°F mineral water is almost considered a water sport, isn't it? My wife thinks so, too.
Edness K. Wilkins State Park is spread out along the shore of the North Platte River and might not be so actively engaged in water sports, but the other nine sites: bring the boat, the fishing rods, the water skis, and the charcoal. Oh, I almost forgot: Sinks Canyon is a place where the Popo Agie River disappears into the ground and then reappears about a half-mile further down the canyon. There's no big lake here but bring your fishing rods and your binoculars: Sinks Canyon is a wildlife paradise.
