Ypsilon Lake – 8.9mi / 14.3km
Ypsilon Mountain reflects in Chipmunk Lake and a partially obscured waterfall cascades into the forested Ypsilon Lake on this hike up in the Mummy Range.
The trail begins climbing up through stately ponderosa pines giving you better and better views of Horeshoe Park and the Alluvial Fan below. You’ll meet up with the Roaring River which splashes through the canyon below. After following up along the river with some nice views looking out, you’ll take a left for Ypsilon Lake.
One of the hike’s highlights is the beautiful setting where you cross over the river. On the other side, you begin climbing up into the lodgepole pine forest. Views are limited as you climb up, sometimes rather steeply, through the scrappy forest. The grade eases as you drop down to the tiny Chipmunk Lake. Ypsilon Mountain reflects in this little pocket of water.
After a few photos, continue along the trail past multiple boulder fields. The trail steeply descends to Ypsilon Lake. The waterfall that feeds the lake can be heard, but isn’t visible initially. To see the waterfall, work your way along the lake shore for a glimpse, then find a spot to enjoy the vantage looking up towards Mount Chiquita to the west.
