Horse Lake Tank is a fairly reliable water source on the Arizona Trail. The water has a good quality after filtration. A single but beautiful campground is located behind a tree at the tree line with a view of the San Francisco Peaks.
Not long after the Horse Lake Tank viewing area, you will come along on the eastern shore of the actual Horse Lake. This viewpoint is from the most northern part of the AZT before it continues even further north away from the lake. This spot offers wide open views of the mountain peaks to the south.
