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) was not my favorite hike or peak I've done. Let's just get that out of the way off the bat. This peak does not have a trail, very little shade, no water, has lots of bush whacking, and is very steep. Now, I've done my fair share of peaks with those qualities, but this one in the Silver Island Mountains seemed to kick my butt worse than the others.
The Subway in Zion National Park is a hiker and photographers dream destination! The Subway follows the Left Fork Canyon in Zion NP, and along the way you'll have a vast view of the canyon, you'll walk along the river and hike by several deep pools, and hike where only 80 people are allowed in each day. After living in Utah for 2 years, I finally got the opportunity to go by applying (and winning) a permit.
Kanarra Falls is a great Utah waterfall hike. You get to hike in a very accessible and beautiful slot canyon, a chance to walk in the river on a hot day, and see several beautiful waterfalls. The biggest downside to this hike is the crowds - it has become a big issue in the past year or so (read about the issues going on here). Kanarra Falls is the perfect stop for amateur photographers looking for professional photo opportunities. This is also a great family hike - it requires only a 2-3 hours, no equipment or gear is needed, nor a high level of hiking skill. Even the kids will love this hike! You'll want to be sure to wear sturdy, water shoes as most of this hike is in the river.
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.
