Best Fishing Spots

The Los Pinos River below Vallecito Reservoir in Colorado is a highly revered spot for fly fishing boasting excellent trout populations. Here are the best spots for the activity:

  • Lower Pine River: This stretch of the river below the dam is accessible from the nearby road. Known for its large rainbow and brook trout.
  • Vallecito Creek: This tributary to Los Pinos River contains smaller trout but offers excellent solitude compared to other locations.
  • Upper Pine River: This area is challenging to reach due to private properties surrounding it, however, it offers great opportunities for catching large cutthroat trout.

All these spots feature clean, fast-flowing water, varying depths and boulder-strewn pools, making them irresistible for fly fishing enthusiasts. It is advised to regard all local fishing regulations and respect private property when accessing fishing spots.

Best Access Points

The Los Pinos River – Below Vallecito Reservoir is a stellar location for fly fishing. Here are some top access points:

  • Vallecito Campground: It offers stress-free river access for fly fishing. The river here teems with brook and rainbow trout.
  • Pine River Campground: Just below the dam, accessible via CR 501. You need to hike in a distance to reach the spots, but the secluded fishing is worth it.
