Daku Arch: Siargao swim-through dive with reef life.
Daku Arch is a boat dive beside Daku Island in Siargao, built around a coral-rock arch with swim-through passages and a sandy slope beyond. It is best on calm bay-side days when the water is settled enough to keep the arch comfortable, but the narrower passage still rewards slow pacing, good buoyancy, and a guide who knows the line around the rock faces.

Warm, relatively sheltered bay-site diving with a coral-rock arch, a sandy slope beyond the swim-throughs, and calm conditions suitable for an easy named-site dive.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Swim-throughs create an overhead environment; maintain buoyancy control in the narrower passage and avoid contact with the coral rock.
Access Restrictions
Boat access only; confirm the day’s entry plan with your operator before the swim-throughs.
Legal Notes
Follow local operator guidance and any area rules before entry.
Community notes to help plan your visit.
Scuba Diving
Includes swim-throughs; the narrower passage can challenge buoyancy control.
Freediving
Capable freedivers can enjoy the arch, but the swim-throughs still reward a relaxed pace and precise trim.
Snorkeling
Snorkeling is secondary here; the arch and fish action are better underwater than at the surface.
