Easy pleasant walk to the reservoir and back. Wildflowers and green grass.



Trailhead Directions

I-25 north to Bernalillo exit 242, west on US 550 to Cuba. East on SR 126 about 10 mi. (just past milepost 10) to FR 70 on left. Drive to Trail 51 parking lot (2-3 miles) at the end of FR 70.

Actual Hike

Hike along Trail 51 (Vacas Tr.) about 2 miles through spruce and fir to reservoir and beyond, along Clear Creek and return the same way. The lake is about 30 min. (3/4 mi.) from the parking area.


Land is very marshy around the lake. They have made “rafts” of 3″ saplings tied together with wire that makes it easier to walk over the soft parts.
