Nope! Large parts of canyonslands NP are so remote you are pretty much entirely on your own. This is actually one of the more accessible areas, but the white rim trail is about 10-12 hours of offroading, so you can imagine you get in trouble around the middle you are at a minimum of 5-6 hours + whatever distance from the park entrance the emergency services are. And thats if you planned ahead and have a satellite communication device to call for help in the first place
