Some Telluride, Colorado summer activities are:
Trails leave town in every direction and loops range from a couple miles to as far as your legs can take you in one day.
There is free downhill biking off the gondola and bikes are permitted on most trails in town.
The San Miguel River has decent trout fishing right in town while several alpine lakes and rivers are less than an hour from town.
The Telluride Bluegrass Festival is world-famous and attracts more than 10,000 people. During the high summer season there is a festival nearly every weekend, including two film festivals, a mushroom festival, a beer brewing festival and more.
Old mining roads traverse the high peaks surrounding Telluride, and a 4 X 4 tour is the best way to see some of the area’s most remote alpine basins.
The San Miguel has Class II-III rapids just down valley from Telluride, and other local rivers like the Gunnison and Dolores host multi-day trips.
The Durango to Silverton train ride is a historic jaunt through the San Juans and has restored vintage cabins and spectacular views. A good daytrip during a Telluride summer vacation.
