(Tillamook, OR) -- The construction schedule at Cape Lookout State Park near Tillamook is changing. The park will now be open in the spring and closed during the summer. Campsites in the A, B, C and D loops as well as deluxe cabins and yurts can be reserved from March 1st through May 31st starting on December 20th. The original plan had camp loops A and B moving to higher ground, but that's being prevented due to geological concerns. Now they'll reinforce the existing dune to keep seawater from entering the camp loops.
