Moab rocks! (pun intended)
Fun town, go to the Love Muffin Café for breakfast, yum.
Best bike shop in town is the Poison Spider.
If you are looking for a shuttle check out Coyote shuttles. As for places to stay? We stayed at the lazy lizard hostel. A cabin with 2 bunk beds was $32. Detached showers, kind of a shithole full of freaky people, but cheap.
Most trails are pretty high skill level and most don’t have large sections of slick rock. The trails are lot’s of rock, and big rocks, but not necessarily slick rock. The Bar M trails are the easiest, some kid friendly loops there as well. The North 40 trail (at Bar M) is pretty fun and is “roadie” approved. Another fun trail system is the “Magnificent 7” or Mag 7. 7 trails that are linked together, 2+ hours, roadie approved.
There is an actual trail called the “Slick rock trail.” It’s in the Slick Rock National Park. It’s 10 miles that will take 2 hours. Lots of really steep ups and downs, crazy ride where 95% of the terrain is on rock. A must do in my book but not an easy ride. Biggest issue with the trail isn’t the difficulty but there is definitely a mental component because the consequences for crashing are high.
