Red Hollow Canyon, a short 1-mile slot canyon in Orderville, UT, is a great stop between SLC and Kanab for a quick stretch with kids and dogs.
Adam's Cabin Trail leads to an old, historic cabin above Adam's Canyon Waterfall. Adam's Cabin was made of stone in the early 1940s, and today you can still sleep in it, if you dare. Adam's Cabin Trail is steep and not for those with knee or hip issues - it gains 2,700 ft in just 2.7 miles!
The Tropic Trail is located in Bryce Canyon National Park, but starts on the East side of the park in the amphitheater, as opposed to the rim and the main park entrance.
Sunset Arch & Moonrise Arch are two arches located within Grand Staircase Escalante National Monument (GSENM) off Hole in the Rock Road. They are both located in an area that does NOT have an official trail so being able to navigate a GPS is necessary. That being said it is pretty straight forward, and this easy hike is great for small children, dogs off leash, and those wanting to see something cool without the hard effort most hikes in this area require.
Devil's Garden is apart of Grand Staircase-Escalante National Monument, and is home to Metate Arch as well as hoodoos. Not to be confused with The Devils Garden Loop Trail in Moab, this area is only 640 acres and is part of a Wilderness Study Area, for the purpose of possible wilderness designation; however, wilderness status was not recommended by the BLM back in 1991. One of the reasons state was that the existing roads, parking lot, picnic tables, and port-a-potty are all in close proximity to a natural area. The second reason was the likelihood of several groups of people coming to this area at the same time to the same formations (all of which are within a 2 minute walk from the trailhead). Both of those reasons diminish the wilderness experience of solitude.
The Horse Flat Trail in American Fork Canyon starts from the Summit Trailhead, and passes through several meadows, large Aspen groves, and shaded areas before finally reaching the Primrose Overlook.
South Mountain (11,817 ft) is located on the very South end of the LaSal Mountains just outside of Moab, Utah.
Mt.Moriah (12,073 ft) is located within Mount Moriah Wilderness in Nevada. This peak is often overlooked by its neighbor to the South, Wheeler Peak, in Great Basin National Park. But that is what I loved about this area - we passed very few people on the roads, and literally no one on the trail! Mt.Moriah is very remote and 4WD and high clearance is needed to reach the trailhead.
Ski Lake is located in between Victor, Idaho and Jackson Hole, WY, and sits at an elevation of 8,650 ft. Locals say this is the easiest alpine lake to hike to in the area at only 4 miles RT! The trail is very mellow and great for all ages, including dogs off leash.
