Delicate Arch & Double 'O' Arch are the must see ones, but the hikes are a bit strenuous and treacherous at places - be careful with young kids. Plan for at least 2 days to see all the main arches. Longer stays can be planned based on the appetite to do more activities. Balanced Rock, Double Arch, Landscape Arch, Windows and Sand Dune Arch are other must-see arches. Great for all family and kids.
