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.
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.
The Darby Canyon Wind Caves are located near Alta, WY, within the Jedediah Smith Wilderness ("the backside" of the Tetons). This is a very popular trail, so don't expect to have any solitude - you'll constantly be pulling over to let others pass, even horses, and the parking lot is full by 10am on weekends. But don't let that stop you from visiting at least once!
Table Mountain (11,106 ft) is located within the Jedediah-Smith Wilderness of Wyoming, and features amazing views of the lesser-viewed side of the backside of the Tetons. The Grand Teton, South, and Middle Teton are the star of the show here, as they tower over Cascade Canyon.
White Pine Lake in Little Cottonwood Canyon (LCC) sits at 10,200 ft, and is surrounded by several peaks. The trail follows an old mining road, so it is very wide and gradual. Even though you'll hike 5.5 miles one way, you'll only gain about 2,500 ft - not bad by Wasatch standards.
Lost Creek Falls is located in Provo Canyon, Utah, and is a perfect Spring hike to check out this fun waterfall. It's great for dogs off leash to explore and cool off in the creek, plus great for kids of all ages. The "trail" starts out by following an old, narrow dirt road, and eventually you are left to hike steeply along Lost Creek.
