I heard that there are some Mayan ruins in the middle of Cozumel that is a self guided walking tour. I just went to the beach last month when we were in Cozumel but saw on the taxi sign as an attraction where the taxi would take you there, wait for you, then drive you back.
Can anyone tell me if this is worth it? It would be a shorter trip than an all day event like Tulum. I also have little kids who wouldn't enjoy the long journey to/from Tulum.
