The nearest recompression/hyperbaric chamber for treating decompression sickness is in Cebu City — roughly 4-5 hours away by ferry/flight combination from Dumaguete, not something reachable quickly by land. This is a genuine, practical consideration for planning dive depth/profile conservatively in this area rather than pushing limits, since emergency treatment isn’t local. Dive-specific travel insurance (DAN, DiveAssure, or similar, covering emergency evacuation and hyperbaric treatment) is worth arranging before diving here rather than after — standard travel insurance often excludes diving-related incidents entirely. Marine Conservation Philippines and most established local dive operators can advise on evacuation protocols if asked directly; it’s a reasonable question to put to any shop before booking multiple days of diving.
