When turning onto Trinity Ridge Road from the south, one should note the sign that says passenger cars and trailers are not recommended. The first few miles are the typical low-maintenance dirt and gravel forest road. As the climb up to the pass on the shoulder of Trinity Mountain starts, the road degrades with washouts, ruts, rocks, and switchbacks. The Hardest Part photo does not do that section justice. It’s not long, but it is steep with large rocks. A true 4WD is needed. All-terrain tires are recommended. Other than the few miles climbing the south side of the pass, the rest of the road is easy. If driving up from the Rocky Bar/Featherville end of Ridge Road, a passenger vehicle should be adequate to get as far as Trinity Lakes. Just above the lakes is the pass.
Trinity Ridge has spectacular views on both sides. Alas, a large portion of the Ridge was burned in 2012, so the view is sometimes obstructed (enhanced?) by standing dead trees. But the view of the nearby valleys and distant mountains is awe-inspiring!
Although there are plenty of opportunities for dispersed camping, the gem of the Ridge is the Trinity Lakes area with clear blue waters, well-developed campgrounds, and many hiking trails.
