Site of the Sea Otter Classic... the race loop is an 18 mile mix of singletrack and forest roads. A trail map is recommended, but hard to find:( Most climbing done on the fireroads, some sweet singletrack can be a little sandy when riding in the valley, there are some other wooded sections of singletrack filled with fun twisting downhill. Gave it a 5 for technicality for some tricky short steep uphills, but overall a great workout with plenty of ups and downs.
101 to Monterey Peninsula exit, the road becomes California Hwy 68. Access the trails via Fort Ord or Laguna Seca of Hwy 68.
