About Kewalo Pipe
Kewalo Pipe is an old Honolulu storm drain turned artificial reef just off Kewalo Basin. The pipe and neighboring finger reefs create a shallow, easy-to-read profile with structure, reef fish, and small critters. It is best reached by boat because harbor and ocean-sports traffic make shore entry awkward and less safe overall.
Safety & Access
Site Conditions
Boat traffic
Safety Notes
Stay clear of traffic, keep a tight line over the pipe and reef edges, and expect occasional surge rather than strong current.
Access Restrictions
Boat access is recommended because the harbor is busy and shore entry is awkward in active traffic.
Legal Notes
Use the harbor approach, avoid shore entry when traffic is active, and do not touch the pipe or coral fields.

Local Intel For Kewalo Pipe
Community notes to help plan your visit.
Scuba Diving
The pipe-and-reef line is best dived slowly, with careful buoyancy around the coral fields and the pipe end.
Freediving
This is not a freedive-first site; the pipe-and-reef line is better handled with scuba and a guide.
Snorkeling
Snorkeling is limited by traffic and the deeper pipe line, so the site is mainly a scuba boat dive.
