Cable Mountain via East Rim Trail and East Mesa Trail
This is a difficult one way trail in Zion National Park.
I did this hike in the winter with my boyfriend, and boy was I tired. I want to give it 4 stars only because I hiked up to Angel's Landing just after and was blown away, but I'll stick with 5 stars since it was beautiful on its own (just not as harrowing/rewarding as Angel's Landing, which is hard to beat!). ★ ★ ★ ★ ★
Out and Back to Observation Point via East Rim & East Mesa Trails.
