Dunns River Park offers two climbs; a wet climb and a dry climb. If you are not a fan of getting wet, then the dry climb would be best suited for you. The wet climb entails walking within the falls, and through the water, so a swimsuit or anything that will dry quickly are suitable for the climb. The dry climb involves a walking trail alongside the falls. Both trails are equally as fun and if you don't want to climb the falls you can take a swim in the beautiful sea water.

Take a boat out on the glowing waters of the Luminous Lagoon and jump in for a swim among the harmless phosphorescent phytoplankton. Swimming is optional. Boat ride tour last for about 45 minutes.
