Nabucco Spice Island is a remote house reef dive on Kusu Island in North Maluku.
Nabucco Spice Island is the north-side house reef at Kusu Island in South Halmahera, a Coral Triangle setting with direct jetty access, coral-rich slopes, and tide-aware conditions. The reef mixes sheltered shallow coral tops with a deeper outer slope, so it works for relaxed reef dives, photography, and small-group exploration rather than a casual drop-in.

Depth range, seasonality, and planning context.
Depth Note
The house reef has calm shallows on the coral tops and a deeper outer slope, so it works for easy surface exploration and longer dives alike.
Best Season
Year-round; October to April is the calmest window.
Typical Conditions
Warm tropical water, healthy coral, tide-aware current changes, and very small-group diving.
Site conditions, restrictions, and access requirements.
Site Conditions
Safety Notes
Plan around the tide and pay attention to the current on the house reef and the jetty entry.
Access Restrictions
Access is through the resort and dive center rather than an open public shoreline.
Legal Notes
Plan the dive through the resort or operator briefing; the house reef is managed as part of the resort dive area.
Community notes to help plan your visit.
Scuba Diving
The house reef directly in front of the resort supports small-group diving, and the wider area offers strong coral gardens, drift dives, and night dives.
Freediving
Freediving is offered on request, and the calmer shallows can work well when the tide is suitable.
Snorkeling
Snorkeling is available, and the reef can be enjoyed from the surface on calm days, though the best action is still below.
