There is more than one trail head to Klondike bluffs. It seemed to me that the better choice is to drive further north up 191 to the second turnoff. It's more central to the start of various trails. If you go to the trail head closest to Moab you ride towards the main group of trails on a very easy path (its a connector trail really). It does allow you to ride the whole of Dino flow down to finish though if that's what you're after. If you start at the lower trail head I'd go up little salty to get to the top of the other trails. It's steep and black in grade but very manageable for a blue level rider.
Fantastic network of trails of various difficulty levels. Highly exposed to the sun, but the scenery and trail quality make up for that. So many loop options. It’s great for an all day ride or maybe just a few short rides.
Easy and challenging rides can be found at this location. In my top three trail systems in moab.
A little slow moving getting there (rough road). Trails could use some directional arrows, but was super fun once i figured it out. Seeing dinosaur tracks on the slick rock was the coolest thing ever!
Some of the trails I enjoyed some not so much. Jurrasic is a good beginner trail but kind of boring. You got to get up into the rocks for the real fun.
