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!
Idaho's Yur-Treat is located just outside Victor, Idaho on the west side of the Tetons. It's about about 4.5 hours from Salt Lake City and tucked into a small grove of Aspen trees.
Gandy Warm Springs is located near the Utah/Nevada border, just north of Garrison, Utah. It's a small natural pool just below Spring Mountain, and the water temperatures are just that - lukewarm.
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.
Red Hill Hot Springs is a popular soaking destination in central Utah, in Monroe. It consists of four pools, all fed by one very hot water source on top of the mound above the pools. Because this hot springs is free (and also on private property), it gets very crowded especially on weekends. The owners allow people to visit as long as the place is cleaned up after and not destroyed. This is a great place for families looking for a really nice hot springs that you don't have to hike it.
