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 says 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.
Corona Arch is one of Moab's most popular trails and one of the most impressive arches in Southern Utah. From Moab, Corona Arch is closer than that of any arch in Arches National Park, and dogs are allowed (whereas in Arches NP dogs aren't allowed to hike any trails).
The Fisher Towers Trail is located 16 miles North East of Moab, Utah, and offers a 4 mile (RT) hike that winds through these fin-like structures. The Fisher Towers are composed of Moenkopi and Cutler sandstone, and have eroded into many shapes and sizes. These towers are one of the most outstanding scenic features of Utah's Colorado Riverway, as the rock pinnacles soar above a maze of red and pink hued canyon, and overlook the Colorado River, Onion Creek, and the famous rock "Priest & Nuns" to the south.
Mary Jane Slot Canyon is one of Moab's hidden gems - the "trail" is a creek the entire way, which leads to a 30 ft waterfall. This is a great trail to do when Moab is too hot, and you, the dogs, or kids need to cool off. The canyon walls get higher as you hike further into the canyon, and eventually will reach upwards of 100 ft! There are several side canyons that allow for exploring tighter slot canyons.
Hiking Upper Muley Twist is located in Capitol Reef National Park (CRNP), and this route covers extremely varied terrain - from deep and narrow, to high and exposed, all within a relatively short distance. It begins in a canyon paralleling the spine of the Waterpocket Fold, a 100 mile long ridge that juts out from the upper crust of the landscape. This long "monocline" is one of the longest in the world! The bizarre landscape is made of brilliantly colored rocks, including at least 7 visible arches, natural bridges, slot canyons, fins, domes, and more. Hiking Upper Muley Twist gives you the grand tour of this area, so it's a must-do!
