At a Glance

  • High-altitude reservoir at 10,000 feet with views of the surrounding San Juan mountains
  • Good fishing for rainbow and cutthroat trout in the reservoir
  • Remote southern location near the Colorado-New Mexico border
  • Loop trail with consistent water views throughout

Overview

Platoro Reservoir sits near the southern edge of Rio Grande National Forest, close to the Colorado-New Mexico border, at roughly 10,000 feet elevation. The 5-mile loop around the reservoir is an easy-to-moderate outing that combines water views, mountain scenery, and fishing access in a remote corner of the forest that sees limited day-use traffic.

The reservoir was built to store irrigation water for the San Luis Valley below, but it has become a recreation destination in its own right. The small community of Platoro nearby provides minimal services, primarily for seasonal cabin owners and anglers who make the long drive in. The loop trail circles the full shoreline with consistent views across the water to the surrounding mountains.

For visitors willing to make the drive from Alamosa or Antonito, Platoro offers a genuine high-altitude lake experience in a remote setting. The combination of fishing and hiking makes it a strong destination for those who want both in a single outing.

The Route

Miles 0 to 2.5: North Shore

The loop begins at the south shore access and crosses to the north shore via a spillway or bridge, then follows the north shoreline east. The terrain is open meadow near the water with scattered conifer forest on the drier slopes above. Views of the Continental Divide ridgeline to the west are clear throughout this section.

Miles 2.5 to 5.0: South Shore Return

The loop returns along the south shore, which has slightly more forested sections. The trailhead parking area is visible across the water for most of the return leg. Several informal fishing access paths branch to the shoreline.

When to Visit

June through October. The reservoir may partially freeze in May and the access road can be snow-affected. July and August are peak season. Fall (September-October) brings quieter conditions and the best views of surrounding fall color.

Afternoon thunderstorms are common in July and August. The open reservoir surface is exposed; plan to begin return by early afternoon on days with building clouds.

What to Bring

Many hikers carry:

  • 2 liters of water (water available from reservoir with filter)
  • Sun protection for the exposed shoreline
  • Fishing gear and license if planning to fish

Practical Details

Vault toilets near the reservoir access area. Cell service absent. Free parking. Review Leave No Trace principles. Camping is available at Platoro Campground nearby. For an overview of national forest camping procedures, see how to get a national forest camping permit.

Getting There

From Antonito (on US-285 near the Colorado-New Mexico border), take CO-17 north and CO-250 northwest approximately 30-35 miles to Platoro. The road transitions from paved to gravel. Check current road conditions with the Divide Ranger District before visiting. The drive is long but scenic, passing through the upper Conejos River valley.

Trailhead Parking
