Fee for diving in the sanctuary is 50 pesos and Jepeeny 20-30 pesos just drop off at the market in Dauin, walking distance to the beach, if you lazy take a trike from the market to the beach, negotiate the price first, no more than 50 pesos for that trip. You need rent table and chairs there (around 100 pesos) if you don't go to a restaurant or resort on the beach. Corals and fish in many colors, nice place

 

Suggest you take the jeepney which commences next to the bakery opposite Robinsons on the corner. The following detail comes from a post someone did in Tripadvisor Aug 29, 2018:
