Enjoyable for all skill levels. No established paths so you can wander wherever you want. Nice picnic area/campground.
Goblin Valley Can entertain you for 1 hour or 10. There are no established trails, so you are free to wander around the entire park. There are cliffs to climb, slot canyons to explore and hoodoos to discover. From the parking area, you descend about 100 feet into the valley. Once you are down there, the whole place is fairly flat unless you decide to climb on things.
One of my favorite things to do is climb up the back wall and look out at the view beyond the valley. It is a drastic difference - a flat, barren landscape.
There is a covered picnic area and restrooms located at the parking lot. I have been here in every season and it is enjoyable each time! The crowds are definitely smaller the winter. No matter what time of year, make sure you see the goblins "hoodoos" after dark. There is a completely different feel to the landscape and the park has some of the darkest skies in the nation which provides opportunity for some great photos of the stars!
