The Ashdown Gorge is located on the boundary line of Cedar Breaks National Monument, and lies within the Ashdown Gorge Wilderness near Cedar City, Utah. The trail starts by following the Rattlesnake Creek Trail at 10,500 ft, and eventually drops into the gorge descending a total of 4,100 ft. This route is best done point-to-point, with 1 over night backpacking. You can definitely do this in one day, but to really experience the canyon and take your time, backpacking this trail is perfect.
Red Canyon is located off HWY 12 near Bryce Canyon National Park, which compared to it's famous neighbor, sees half the visitors. And for good reason - there's no national park name attached it, and many people do not realize how many trails are in the canyon. In particular, the Cassidy Trail, is one of the best in the canyon. No fees, dog friendly, shade, and amazing views all located in the Dixie National Forest - does it get any better?
Pine Creek Canyon is a hidden gem in the Escalante area - a pristine creek, tall canyon walls, half mountain-half desert, no cows, all downhill, plenty of shade, and towering Ponderosa trees. Located in the Box-Death Hollow Wilderness, this canyon is also known as "The Box", which is funny since it's not really a box canyon but steep-walled, open-ended drainage carved by Pine Creek millions of years ago.
Bowington Arch is located in Grand Staircase Escalante National Monument (GSENM) near the town of Escalante, UT. It's an easy hike that crosses the Escalante River several times, and therefore it's important to wear water shoes. You will also hike through sandy sections with sage brush and cottonwood trees. Bowington Arch is dog-friendly and (possibly) kid friendly. There are no obstacles of any kind except for one small scramble the the dogs can easily do, and some younger kids might need help with. I say possibly kid friendly since this trail is close to 8 miles round trip, but is completely flat the whole way. Make sure you have a map of the area downloaded on your phone or GPS, as there is no sign for where to turn off for the arch. I highly recommend the Gaia GPS app.
The Escalante River Trail is a popular backpacking point-to-point route near the town of Escalante, Utah and within Grand Staircase Escalante National Monument (GSENM). The entire length of the Escalante River is 87 miles, but this route allows you to see 15 miles of it overnight one night of backpacking. Much of the way, your path will be the river itself. On a blue sky, warm & sunny day, splashing through the stream along tall Navajo sandstone walls feels amazing. Around every corner is something new and exciting to look at. The Escalante Natural Bridge. An arch. Petroglyphs & pictographs. Ruins. You name it, it has it.
