Due to a very tight itineary we will only have 2 nights, 1 full day on Coronado. Originally we thought we would stay around Old Town somewhere but came across some very good pointers to Coronado while doing some research into what to see and do around San Diego which we have visited before some years ago, but staying on Coronado really appeals now. Would it be possible to see round the island by bike if we rented one for either a half or full day? Any must see sights doable by bike? We are 2 reasonably fit and health retirees so imagne a simple flat bike ride well within our capablities. Hopefully we intend to stay at La Avenida so would use that as a starting point. Any suggestions gratefully received!
