The state's signature
Aspen gold + the La Junta tarantula trek
Two shows share September: high-country aspens flip to gold in a two-week rush, while on the Comanche grasslands thousands of male tarantulas walk their autumn mating march — best seen from Highway 109 in the hour before dusk.
Seasonal RV-timing verdict
When Colorado is at its best
Colorado's prime RV window is June to September. High country is accessible and wildflowers peak; winters bring heavy snow that closes many mountain roads and campgrounds. Shoulder-season play: Late May and early October have beautiful weather in many areas but snow can still appear overnight in the mountains.
Know before you go
Afternoon thunderstorms are common in summer; altitude sickness is real above 8,000 feet. Winter driving requires chains or 4WD.
