Ibapah Peak is the tallest point in the Deep Creek Mountains and Juab County, at 12,087 ft. Getting to to the trail head is a long drive, since it's about a 4 hour drive from SLC.

Rishel Peak (6,196 ft) is a fin-like peak created by volcanic activity, and is located in Utah's West Desert in the Silver Island Mountains. There is no trail, no shade, no water, and no true parking area or signs. Be aware that you MUST have a high clearance or 4X4 car to drive out here, and be prepared for flat tires from old mining nails still scattered about.The best time of year to hike this peak is in Spring or Fall when the temperatures are not as hot. Because this area is BLM Land, you can camp for free anywhere. However, there are no established camping areas, and Leave No Trace principles apply.

Cobb Peak (7,021 ft), located in the Silver Island Mountains of Utah, is one of the toughest and most rugged peaks I've attempted—and honestly, not one I’d rush to do again. If you're planning on hiking Cobb Peak, here’s what you need to know to prepare for a steep, exposed, and route-finding-heavy adventure.
Kayenta Canyon Trail is known by two names: Kayenta Canyon, and to the locals, Hellhole Canyon. This trail starts in the town of Ivins, UT, about 15 minutes west of St. George, UT. If you don't like walking in sand washes, this is not the trail for you. 90% of this trail is walking in the wash, and on a sunny day (most days in Southern Utah), it can get very hot. There is no water, no shade, and no restrooms.
