My perfect combination is yoga plus water - that's what makes a land-locked mermaid happy. Even though Colorado is smack-dab in the middle of the U.S., there are water activities aplenty from expansive lakes to gushing rivers.
Heck, you can even "surf" by tying yourself off to a bridge over an enthusiastically flowing river.
(But I'm more for the stillness, personally).
Lake Dillon offers pristine waters and crisp mountain air as the most natural yoga studio you can ask for. There is always an opportunity to bring your own paddle board to explore the waters. Sometimes you'll find a yoga teacher training class, like this one hosted by Stoked Yogi.
One thing is for certain: The combination of community and natural beauty make it hard to get back into the walls of the studio.
