Arches National Park: Delicate Arch Trail
Additional Tip: follow advice to wear spikes when there is snow or ice. The very last part of the trail has drop offs and we even saw skid marks of someone sliding off the trail earlier that morning!
Zion National Park: Angel's Landing
This is a strenuous 5 mile roundtrip hike with sheer drop offs. I do not recommend this hike for anyone with a fear of heights. Honestly, I am still a little surprised I did the hike in the snow...thankfully we rented some great yak spikes that made the hike doable.
If you are up to this challenging hike, it is extremely memorable and beautiful. We even saw a condor soaring at the peak.
