Tulamben macro shore dive with a gentle volcanic-sand slope.
Tulamben macro shore dive with a gentle volcanic-sand slope.
Sidem is a Tulamben macro dive with a gentle volcanic-sand slope, scattered rubble and small coral patches that reward slow, careful searching. It is a shore-entry site best for patient photographers and precise buoyancy, with calm conditions, easy access, and a strong day-to-night shift that makes after-dark dives especially productive.

Depth range, seasonality, and planning context.
Reported Depth
5m - 30m
Depth Note
Shallow plateau begins around 5m and the slope carries the main macro zone to roughly 30m; most critter hunting stays shallower.
Best Season
April-November, especially the dry season and calm mornings.
Typical Conditions
Calm, protected black-sand conditions with a gentle slope, sparse rubble and small coral patches; visibility is usually good to excellent and current is typically mild to none.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Keep buoyancy tight over sand and rubble so you do not silt out the macro zone or touch delicate critters; watch the entry and exit if waves build.
Access Restrictions
Pebble-beach shore entry is best on calm days; surf or chop can make the entry less comfortable.
Legal Notes
Standard local dive access applies; follow operator briefing and shore-entry etiquette.
Community notes to help plan your visit.
Scuba Diving
Best for slow macro dives on black sand and rubble, with small coral patches, day-and-night critter hunting and careful photography.
Freediving
Not a primary freedive target; Sidem is better suited to scuba macro dives where slow bottom time and buoyancy control matter.
Snorkeling
Snorkeling is secondary; the site's main value is below the surface on the sandy slope and rubble patches.
