Bloods Lake is a local favorite for people on both sides of the Wasatch because it straddles the border between the two. You can easily access the trailhead from the cities of Salt Lake, Park City, and Midway by heading toward Guardsman's Pass. The dogs of the Wasatch Front love Bloods Lake because they are restricted anywhere west of the pass, and this is one of the closest watering holes for them to legally take a dip in a lake. The property is actually private land, but people are given free access to enjoy with their entire family.
The trail is not very difficult because it is only half a mile to the lake, but keep in mind it can get pretty steep toward the bottom and the smaller kids might need assistance at that point. Expect to see a ton of wildflowers in the late summer as well as a moose, marmot, or a swarm of hummingbirds. Bloods Lake is just the first of several lakes in the area accessible from here, Lackawaxen, Brimhall, and Silver Lake are also just short distances away.
A rope swing on the west side of the lake provides a little extra fun for those who aren't quite satisfied with slowly entering the frigid mountain water. There are also a few fire pits and logs set up for seating near the northwest side of the lake. The pass is closed during the winter and can only be accessed from May to October. The dates are not set in stone so check road conditions for seasonal road closures and opening days in Utah.
Remember to be respectful: This is private land and the owner could change their minds about access if we don't treat the area respectfully.
