I am offering courses in freediving, also called apnea diving, in Panglao, Bohol in central Philippines. I'm an instructor at Freedive Panglao which, in my opinion, is the best place to learn freediving in the Philippines, and maybe in the whole of Asia.
Panglao is a beautiful island close to Bohol located in central Visayas in the Philippines. The closest town is Tagbilaran in Bohol, with is just a 20 minute motorcycle ride from Alona Beach, the most famous beach in Panglao.
The island is perfect for apnea diving since you have a drop off that goes all around the island. Some places it drops right away, but other places you need to swim a bit or take a boat.
Panglao offers great diving opportunities both for freedivers and divers that prefer to use tanks to experience the underwater world. There are plenty of scuba shops around.
Just One Breath freediving offers courses from AIDA (Association Internationale pour le Développement de l'Apnée)
