The Passage is a narrow Raja Ampat channel between Gam and Waigeo that feels like a river cut through mangroves and limestone cliffs. The route is a tide-driven drift with shallow walls, caves, grottoes, and quiet edge pockets instead of a broad open reef. It suits experienced divers who can handle strong current, and boat timing matters because the light and flow change quickly through the day.

Depth range, seasonality, and planning context.
Reported Depth
1m - 35m
Depth Note
The channel is shallow in the middle, with about 5m in the main section and walls that drop to around 35m.
Best Season
Year-round; October to May usually gives calmer seas and better light before noon.
Typical Conditions
Strong current may be present and can create a fast drift through the canyon.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Plan the dive with a guide, keep buoyancy tight near walls and ledges, and expect the current to change quickly with the tide.
Access Restrictions
Boat access only; tide timing and guide support are part of the normal plan here.
Legal Notes
Follow local park and operator rules.
Community notes to help plan your visit.
Scuba Diving
Best as a guided drift dive with current control and solid buoyancy; the shallow edges reward photographers who can hold position at the margins.
Freediving
Only suitable in the shallowest sheltered edges with an experienced guide; this is not a casual freedive site.
Snorkeling
Guided snorkeling works best in the shallow channel edges and on calm, sunny windows before midday.
