The Great Chamber at Cutler Point is a large open dome with a tall sand hill - perfect for photography. This is less of a hike and more of a scenic viewing area, as long as you can drive all the way! The roads are extremely sandy - high clearance and 4x4 is a MUST.
Alstrom Point is a vast, open overlook at the edge of Lake Powell, and offers amazing views of Gunsight Bay, Navajo Mountain, and tall red buttes. It's considered one of the best views in Southern Utah, and requires an SUV or larger to reach the end of the road at the overlook.
Wiregrass Canyon is one of many drainages that flow into Lake Powell, and offers a fun moderate hike. If you had a full day, you could reach the shore of Lake Powell, but most people only hike to the arch and back in just a few hours. Wiregrass Canyon Arch isn't the only attraction - tall, white canyon walls with two sections of light scrambling make this enjoyable for the whole family. The first 1/2 mile winds through a dry wash, before entering the canyon, where the fun begins.
Hiking Catstair Canyon is a fun, quick, and easy hike for the whole family. It's only 0.5 miles RT, and leads to two sections of stacked cars right underneath HWY 89!
Anniversary Narrows Slot Canyon is located within the Lake Mead Scenic Byway area, just outside of Las Vegas, Nevada. Hiking this trail is best November through March when the temperatures are much cooler.
Turtlehead Peak (6, 323 ft) is located in Red Rock Canyon National Conservation Area, and one of the most popular hikes in the park. To reach the trailhead (TH) you must have a timed entry reservation for Red Rocks (get that here), and start hiking early to beat to people all the people and weather. Turtlehead Peak offers amazing views of the entire area, and on a clear day you can even see the Las Vegas Strip!
Lexington Arch is located within Great Basin National Park, yet very few people make the trek to it due to it not being in the main area of the N.P. In fact, access to the trailhead was closed for a long time due to the "Strawberry Fire" of 2016. Then a flash flood ripped up the road leading to the original TH. Now, hikers have to add an additional mile of hiking before reaching the official TH.
Paul Bunyan's Woodpile is an interesting geological feature in Central Utah, that looks like a "woodpile" of logs left behind by the giant lumberjack of American & Canadian Folklore. Really the woodpile is a cluster of lava rocks formed about 30 million years ago; the logs were then formed into orderly columns.
