A charming little town in the Rocky Mountains, it has a past as a mining settlement and a present as a tourist destination. On the southern side of the valley is a ski resort with hiking trails, and further east, untouched areas are located beyond the ski slopes. On the northern side of the valley, there are hiking trails and plenty of nature.

For a ski resort built from scratch in the 20th century, Mountain Village is quite impressive. Hiking, mountain biking, and golf are available in the summer. A weekly public scientific lecture is held for laypeople, for which one participant is selected from one of the workshops taking place that week in Telluride.

CR 250 is a much quieter and more scenic alternative than the traffic-ridden US 550 that travels through the middle of the valley. There are tall mountain walls on one side of you and views across the valley towards the La Plata Mountain Range in the other direction.

Encompassing well over 4 square miles and situated within San Juan National Forest, Vallecito Reservoir is a must-visit if you are out for a bike ride near Durango, Colorado. The long road following the west shore of the lake is paved, and the roads and paths on the east side of the lake are dirt.

You can spot Lake Nighthorse from here. If you have your gravel bike with you, you get an even better view by biking up towards Smelter Mountain on the dirt CR 212.
