I don't know that I would go more than an hour out of my way to visit again, but I'm glad we made the trek from Denver this once. It was not crowded on a pretty weekend day, but it was extremely muddy in the winter, to the degree that I almost lost a shoe once or twice. That said, it's very unique. No dogs are allowed and I think that is definitely acceptable because this is a clearly fragile environment that needs to be protected. If you want a place to take a gentle walk with out of town visitors, or need photos of you on Mars for a dystopian futuristic film--- this is it ;). And bring a separate pair of shoes for the car ride home.
