Kitchen Creek Road used to be a through route between Mt. Laguna and I-8 to the south, however, the middle section is now permanently closed. The upper section has roughly a 600' elevation difference, so it's relatively flat but permanently gated at 2.5 miles.
Along this route, there are many spurs and sites for dispersed camping. The road itself is easily traversable with any 2WD vehicle, but the spurs and access to the campsites range from easy to almost impassable.
This route is in the Cleveland National Forest and may require an Adventure Pass and/or Campfire Permit (even for gas stove use).
