Fees vary meaningfully across the sites covered here, worth knowing before budgeting a multi-site trip. Apo Island Marine Sanctuary: ₱100 for Filipino visitors, ₱300 for foreign visitors, plus a mandatory guide fee (~₱300/group) for the Turtle Sanctuary area — separate from the ₱3,500+ banca charter fee to reach the island itself. Salagdoong Beach (Siquijor): entrance historically around ₱20-30 plus ₱10-20 for parking — a day-use beach fee rather than a dive-specific one, relevant if combining a Siquijor beach day with diving elsewhere. Reef Dive Site (Dauin/Apo area, per source map data): snorkeling gear set ₱150, guide fee for 2 people ₱250, with independent unguided snorkeling reportedly not permitted. Dauin’s shore-access muck sites generally don’t carry separate marine park fees beyond what a resort/dive shop bundles into its dive-trip pricing — confirm with the specific operator rather than assuming a flat area-wide fee.
