Whether we're on Devil's Backbone or Trail 666, Colorado's got some wicked good hiking spots. Trail 666 does not in fact lead to Hell; it's actually very beautiful and has almost a five-star rating and great reviews from hikers.  

Alltrails.com says that 'Trail 666 is a 8.4 mile lightly trafficked out and back trail located near Colorado Springs, Colorado that features a waterfall and is rated as moderate.'

It's even listed kid and dog-friendly, just remember to keep them on a leash (the dogs, not the kids).

If you plan to visit (if only for the Instagrams alone), reviewers have noted that a portion of the trail is closed for restoration. Hopefully no one steals the sign though, because Trail 665.99 just doesn't have the same ring to it.
