Fantastic place to challenge ones strength, ape index, and endurance. Horses are welcome as well aside from well mannered little people! There is a trail for ultra marathoners (50K) for humans and horses. Great moderate routes and awesome harder climbs; multi pitches that are quite enjoyable are also vast at the Castle.
Best to leave the furry friends at your campsite. Other wild animals also around - coyotes, cows, maybe moose if you're lucky😜
Best park service crew in the nation if you ask me! The out house toilets are definitely cleaner than most public restrooms. . . Thanks to the Park's crew👍
