For anyone who wants to get out on the water, RIGS Fly Shop & Guide Service is located just up the road in Ridgway, Colorado. They offer guided fly fishing trips on six rivers in the area.
Just a short walk from town there is a 285-foot waterfall that plunges through a narrow quartzite canyon with rock walls towering nearly 100 feet above. There are a few trails ranging from easy to moderately difficult, plus a nature center with exhibits. We have never had to pay for this, but the exhibits may cost money.
There are a ton of other things you can do in Ouray, the website attached takes you to all the options!
