The geography of Barra de Navidad and the the Grand Isla Resort is kind of tricky. There is an estuary that separates Colima from Jalisco. The Grand Isla Resort is on the Colima side and Barra de Navidad is on the Jalisco side. There is a tiny fishing village called la Culebra on the Colima side but most of the local population lives in Barra de Navidad or Melaque (the next town up the coast). The Grand Isla Resort has a couple of private beaches and a little dock where you can catch a water taxi across the channel to Barra de Navidad. I was able to paddle my surfboard across the channel and around the jetty in about 10 minutes. It is very quick.
