Catch some sun and get some of the best low impact exercise around.
At PCH and West Channel there is a tunnel that goes underneath the highway leading you directly onto the beach. In the tunnel take a left up the stairs onto the bike path. Head south 250 feet and you will hit the first set of courts but be aware you will need lines for these courts! If you want courts that have lines continue heading south to the Annenburg community center. It is an eight minute walk down the bike path and they already have lines on the courts.
The photos are of the North Courts which you will find if you head North on the bike path, but you also will need lines here and there are not as many official height nets left.
