We originally thought we might go a little farther away to Rincon, Arroyo Hondo and Gaviota, but finding all the local beaches from Haskell's in the "north" (west) all the way to Miramar in the "South" (east) kept us quite busy. (We did visit a few beaches outside of this in 2016: El Capitan, Refugio, Padaro and Carpinteria City Beach.) We didn't venture to Rincon or Gaviota. (Some day after COVID I will go to Gaviota with you Monica!)
We did try to visit Arroyo Hondo Beach. We followed the directions, but found the path down to the beach too steep for us to go down (also there is a train track crossing as well) so we turned back. It is a fun place to visit to see the old bridge on the southbound 101.
