Los Peńasquitos Canyon

San Diego, CA


There are several trailheads and staging areas, but I will list my favorite: Elizabeth Rabbit Neighborhood Park. This park is brand new. It has two large flat paved handiman spots, running water bathrooms and a drinking fountain. It provides easy access to Cobbles, Carmel Mountain Road Path and the Preserve Path. For a staging area near the East Trailhead off Black Mountain Rd, see my PQ Canyon aMTB1 Safe Solo Loop. There is also a third, very large paved staging area with an accessible porta potty at the southwestern Sorrento Valley Trailhead.

AMTB1 TRAILS - No Obstacles Exist

AMTB2 Trails - some Obstacles Exist - Support Rider Recommended

  • Carmel Country Connector - Chain gate that could possibly cause a problem for solo rider

  • Carmel Mtn Psychopath - Singletrack with narrow camber

  • East Deer Canyon - Ride around at trailhead. Narrow with steep loose climbs. Awkward creek crossing

  • Eucalytus DH - Most aMTBs will be fine, but this is an experts only DH trail with deep ruts and tightness at the end. Access from the Switchbacks Rim Fire Road, NOT West Rim. West Rim (aMTB3) has a lot of off-camber. First DH section is very steep, loose and rocky. After trailhead for Switchbacks, is main DH section.

  • North Side Trail West - West of Two Bridges, North Side Trail has a section of single track with a technical rock garden and narrow bridge.

  • Ranch House Crossing - 48” bridge but there is a technical rock drop/climb at north end

  • Santa Monica Ridge - All fire road and would be aMTB1 except for one pinch point with a rock and gate. Consult POIs on suggested loop

  • Sycamore Crossing - 48” bridge but there is a small rock drop/climb on south side

  • The Shits - Super fun, experts only downhill. Steep berms and paver turns.

  • Two Bridges - Technical rock gardens, narrow bridges and off camber

  • Tunnel 4 - Best trail in the area. Narrow and cambered.

  • Wagon Wheel Crossing - 48” bridge but puddle forms at bottom of steep ramp on north side. Difficult to get up it with wet tires

  • West Deer Canyon - Close to being aMTB1 except for some narrow technical parts. Barbed wire fence with 36” opening. East to west only recommended. Use Won’t Fall In for exit. West Deer Canyon “Dont’ Fall In” is impassable.
