This excellent hike in Pingree Park takes you to some amazing lakes high in the Northern Colorado Rockies. It is 5.7 miles one way from the trailhead. Emmaline Lake is incredibly scenic and takes about a day for most people (even if you’re faster, you’ll want to take the whole day and explore). At and near the top, you are surrounded on three sides by the high mountain ridges of Comanche Peak and Fall Mountain. There are ways to the top, but they almost all require some scrambling. There are multiple little ponds, large rocks to climb on and explore, and it’s overall a nice little area that is kinda fun to spend a day.
One of the lowest 14ers in elevation, at 14,011 ft (USGS), Mt. of the Holy Cross is a challenge as well as a spectacle. It is such named due to the cross-shaped snowfield on the northeast face. The first recorded ascent of the mountain was in 1873, but it is very likely to have been previously ascended by Native Americans or mining prospectors. Holy Cross is the highest peak in the northern Sawatch Range.
