From Scuba Do it is about a 50 minute drive to Playa Lagun. Drive towards Westpunt and follow the signs for Soto/Lagun. Playa Lagun is situated shortly before Lagun on the left hand side.
You can park your car at the parking lot and get your equipment ready there as well. Enter the water and swim slowly in about 10 minutes towards the blue line. The drop off starts at around 8 meters.
The reef is hilly and slopes very gently whereby you get a very good and wide field of view. You have high chances to see some green turtles, also right in the bay. There are many different kinds of corals under which are many sponges.
