Peñon Bobo

Start the dive next to rock's north wall and dive all the way to 60-70 ft. Head towards the reef (west). Then follow the reef and continue north until you find the entrance of a big cave. Enter the cave all the way to the end and you will find a tight exit. No dive light needed. You may exit the cave through this hole only if the surf is calm. Try it, if the current is too strong then back up and return to the deeper waters of the cave entrance. Head back to the boat. Just a 10 minute boat ride from Capurgana's pier halfway to Zapsurro, anchor north of rock island (Peñon Bobo) where the reef begins. Not possible all the time, only when the sea is calm.
