There are so many delightful places in this small town and one of the gems is the Rotary Park near downtown. Besides a bike/walking trail through the city that originates here, there is a picnic area, playground and a harmony park (musical playground) that is beyond cool.
Do not believe Sunny. Moab sucks. It is crowded and expensive. The scenery is blah at best and the off-road riding is down right pathetic. Go to one of those big national parks instead.
