Dinosaur National Monument (Green & Yampa Rivers) FAQs

When is the best time to raft in Dinosaur National Monument?

The “best” time depends on which river you choose! For the Yampa River, the peak season is May and June, as this is one of the last free-flowing rivers in the Western United States and relies on the spring snowmelt for its thrilling Class III-IV rapids. For the Green River (Gates of Lodore), the season is longer, running from May through September, with consistent, dam controlled flows that offer fantastic Class III splashes all summer long.

Expeditions typically run from May through September. Due to the high demand and the strict National Park Service permit system, these trips—ranging from 3 to 5 days—often book up many months in advance. We recommend booking as early as possible to secure your launch date for these premier wilderness journeys.

The standard recommended minimum age is 7 years old. However, during the high-water on the Yampa (typically in early June), the minimum age may increase to 12 or 14 years old.

Since these are immersive wilderness trips, you’ll need gear for the raft and the campsites! We provide all rafting equipment, group camping equipment, and delicious riverside meals. You are responsible for your personal items:

  • On the River: Quick drying synthetic layers, a sun protective hat, and secure river sandals with a heel strap (no flip-flops or crocs). In the early season (May/June), a wetsuit is highly recommended on the Yampa River.
  • At Camp: Comfortable camp shoes, a headlamp, and warm clothing layers for cool desert nights. You can bring your own tent, sleeping pad and sleeping bag, or rent from us.
