Back way into Great Sand Dunes National Park. Camp in numbered designated sites only along route inside park or at Pinon Flats Campground. Picnic next to stream at base of giant sand dunes. Great fall color. Fee required entering or leaving park at main gate on south side. Unlicensed vehicles are not allowed inside the national park, but you can access the 100-mile-long Rainbow Multi-Use Trail via F.S. 412. MVUM for 2009 shows this trail open to 50″- wide vehicles all the way to Hermit Pass, Trail #98, and beyond.

Traveled west to east in a stock ’19 Wrangler Rubicon Unlimited with tires deflated to 20 psi. Great trails with amazing views, quite a bit of traffic over the Labor Day weekend. Creek crossings were shallow with the exception of one that was almost to the bottom of the Jeep, but the creek beds are rocky so there was no problem crossing them slowly. Lots of dispersed camping sites, but all taken or reserved by empty vehicles parked on them. This would be a perfect first time trail, the most difficult part being the soft sand near the Great Sand Dunes National park, you will definitely want to deflate your tires. Due to the close proximity of the park, and the dispersed camping, there is a fair bit of traffic on the trail in case you get into trouble, and we saw two park rangers while we were crossing it. There are a few mildly rocky sections, but nothing outside the scope of a novice in an adequately capable vehicle.
