Big Thompson River

The Big Thompson River is 78 miles long and originates in the Rocky Mountains within Forest Canyon. It is also a great spot for engagement photoshoots! The Big Thompson River begins in the heart of Colorado’s Rocky Mountains, high above timberline. From Estes Park, the trail heads west towards Moraine Park inside Rocky Mountain National Park. From there it continues on to Loveland and beyond! It keeps going west until it merges with the South Platte River south of Greeley.

The number one activity on this river is fishing, as there are plenty of great spots to cast a line in its headwaters. However, this river is not the best place to visit in summer because of its high elevation. Experienced rafters will love the almost 8-mile section of Big Thompson in Larimer County. The stretch of water in this area is rated Class III-V, which promises an exciting workout for rafters and kayakers.
