Siladen Island Resort & Spa is located on Pulau Siladen to the north of Sulawesi. Siladen Island can only be accessed by boat, but, fortunately, it is located only a few kilometers from Sulawesi Island’s north coast and the main port in the city of Manado. Sulawesi also has an international airport at Manado.
The island resort is in the heart of the Bunaken National Marine Park, one of the oldest protected areas in the Indonesian “coral triangle”. The property is located on the western side of the island on a 300 meters long stretch of white coral reef beach facing the Manado Tua volcano. The island is entirely fringed by coral reefs offering fabulous coral drop-offs.
The best area for snorkeling is located between the Island’s southern point (Onong Reef) and the entrance to the Siladen Island Resort & Spa. In the south the shallow waters inside the reef edge support numerous hard and soft coral assemblages. Further north sand patches are evident and extensive seagrass beds exist. The reef edge is very close to shore (50-60m) in the south, with the lagoon behind the reef edge gradually increasing in size until the drop off at the reef edge is about 500m from shore opposite the Siladen resort.
Considered to be a good site for night snorkelling but probably best conducted by one of the trips organised by resort.
Climate and sea conditions
Siladen has a tropical rainforest climate. Year round temperatures are high with daily averages generally around 27C and maximums up to 33C during the period September to November. Maximum chance of rainfall occurs between November and January, with the lowest chance of rain in September. Winds are light all year, rarely approaching 12 knots. The windiest periods are between July and September. Strongest winds blow from the WSW and NE.
Seawater temperatures are between 28C and 30C all year round and visibility is in the order of 20m but may be much more. Tidal range varies between 0.3 and +2.5m. Make sure you have identified a safe exit point given that on a large spring tide you may not be able to exit where you entered, particularly of the seagrass beds. The large tidal range on spring tides will also create strong localised currents. Check with the locals for advice.
Vessel activity is low but small boats use the jetty and the beach opposite the village, so be aware.
