Great hiking trails, mountain biking for the moderate/novice is do-able. Didn't expect to gasp for air so badly in some areas wondering if I'd trained hard enough for this, but perhaps it's pressure changes in certain areas because theses spells lasted less than 1/4mile. Carried 1.5L/h20 per person and did fine from 9a-2p with a stop for a small packed lunch on the trail. Photography potential is phenomenal. Camping was great fun, too hot for a fire at 106degrees. Makes ice seem like a gold commodity. Pay attention to park hours, no admit after 10pm, not alot of food options around but there is one store with food/snacks/ice/souvenirs in the park open normal business hours. Sunscreen, a good hat, camelback for water and a snack on hand at all times is necessary. Flies bite too, maybe some spray, they're worse in the afternoons. Park fee is minimal per person.
