Best for advanced divers, shore & boat entry, moderate current.
Fremont Canyon is a freshwater site where the North Platte River enters a dramatic canyon. The topography features steep underwater rock faces and significant drop-offs. Snorkellers can access the water from the shore or by boat. Conditions are challenging, with deep water, moderate currents, and consistently cold temperatures that can drop to 8.3°C in late May. Due to the depth, strong currents, and cold water, this site is suitable only for advanced snorkellers. Parking is available for visitors. Boat traffic is a known hazard in this area, so users should remain vigilant while in the water.
