The Amasa Basin OHV trails are located in Millard County Utah approximately 51 miles west of Delta, with good parking located off Utah Hwy 50. There are approximately 33 miles of trails and gravel roads in this trail system. It will take you all day to explore this system and it is well worth the trip. There is a large sinkhole (stay outside the fence) and the view from the top is identical to that from Notch Peak without the 8-mile hike.

There are no services so stock up on anything you need before leaving Delta (or Milford if you are coming from the South) This is a great place to get away and enjoy some solitude while exploring a seldom seen part of Utah.

The riding is pleasant and scenic, trails vary from easy to difficult. Trust the trail ratings. The black trails are not for beginners. We descended from the top on Trail 6 and while the map shows it as a blue trail you will find the markers on the ground have it as black. It has some very tricky sections even going downhill, that may not be passable without winching going uphill.

It won’t take you long to move up in elevation and the scrub brush turns to Pinion Pine trees and Juniper.
Then the Pinions turn to giant boulders and a few more leaves.
From the top of the mountain, the view is endless.
The trail narrows and is heavily washed out with many large boulders to work your way around. Beginners may want to skip this short section.

The trail ahead is not for expert riders only.

The trail ends at the edge of a Wilderness Study Area. We walked from here. It is possible to hike across to Notch Peak from here.
If you choose to return on Trail #6 be aware that it narrows significantly and heavily scrubbed both sides of our 50″ RZR. A larger rig could suffer significant paint or trim damage.
While this section is rough, rocky, narrow and slow, the views are spectacular.
The last leg returning to the Trailhead is wide and smooth, a nice reprieve.

Best in a pickup, lots of dust if there are others. Rock hunting areas around. Best in fall and spring it can be very hot.
