Access Notes
Understanding road ratings for trailhead access
Trailhead access is via paved road. These may be seasonally closed, but should be accessible to all vehicles when open.
The trailhead is accessed via some dirt road, but the road should be accessible by most vehicles.
These access roads are rougher, with ruts, bushes, bumps, etc. that require a bit of clearance. Examples of vehicles that, carefully driven, should be able to reach these trailheads include: Subaru Outbacks, Toyota Rav4s, 2wd trucks, SUV's, etc.
For reference, if I call it high clearance, I did (or would) take a RAV4 or Subaru Forester to the trailhead. Storms, mud, or lack of maintenance can turn high clearance roads into 4x4 roads. Bringing a shovel "just in case" is recommended.
The real deal. Big rocks, ruts, washes, and other terrain that require a vehicle rated for difficult terrain. Driver skill also matters on these roads. I would recommend these for 4x4 pickups, Jeeps, and other true 4x4 off road vehicles. Size also matters, with a smaller 4x4 often better suited for navigating around obstacles than a larger one.
