Located at the heart of the coral triangle, the Bunaken National Marine Park (BNMP) covers a total area of over 890 square kilometres.

With more than 390 species of coral living within the park’s boundaries, it is among the most bio-diverse marine parks in the world. The extraordinarily high levels of marine diversity, combined with the ease of access, put Bunaken National Marine Park high on the list of every ocean enthusiasts bucket list.

What to Expect

Bunaken Marine Park is famed for its rich macro life and pristine shallow reefs — with the latter being more of interest for snorkellers. 

While snorkelling over any of the twenty-plus sites within easy reach of Siladen Resort & Spa, you can expect to see healthy and seemingly endless coral reef gardens dotted with enormous sponges and anemones blowing in the current. 

Huge schools of reef fish are common in the shallows, and turtles are spotted on almost every site that we visit for snorkelling — sometimes as many as 15 in an hour. Larger species such as reef sharks, eagle rays, or napoleon wrasse are regular sighting by snorkellers too. 

Snorkelling Conditions

The reefs surrounding the island start very shallow and slowly deepen to around 5 metres before the wall plummets into the deep. The average tidal excursion is between 1.5m and 3m, meaning you are never far from the action. 

The visibility is generally good year-round — with an average visibility of around 30 metres. The visibility over the shallow reef near mangroves can be negatively affected by the outgoing tides, although we always plan around the tide. 

Currents can be strong and unpredictable, so we always conduct a current check before entering the water, and we always follow the current during our snorkelling sessions. The boat will pick you up when you are ready to leave the water. 

The average water temperature throughout the year is 28 Celsius, although upwellings from the deepwater below can cause dramatic temperature fluctuations — sometimes varying up to four Celsius on a single site. We recommend all snorkellers either wear a full body suit or at least a long-sleeved rash guard used in combination with a reef-friendly sunscreen. 

Boat Excursions

The best way to experience the variety of snorkelling in Bunaken Marine Park is by joining one of our twice-daily scheduled boats. Included in the boat excursion is a snorkelling guide, who will take guests at a ratio of four guests per guide (4/1). The boats are either a mixture of divers and snorkellers (with sites planned that suit the needs of everybody) or just snorkellers. 

Upon arrival at the site, you will be given a site-specific briefing explaining the site’s topography and what you may expect to see, followed by important safety information. The amount of time you want to spend in the water is completely up to you. We generally brief for 70 minutes per site, but this time is much more flexible for snorkellers than it is for divers, and it is not uncommon for guests to spend much longer than this in the water. 

Besides the morning and afternoon snorkelling, you are also very welcome to join the boats at night for night snorkelling. Night snorkelling can be an amazing experience, but you need to visit the right sites to have the best experience possible. Luckily, our dive and snorkel guides know exactly where to take you so you enjoy your night snorkelling session just as much as the divers do. We depart from Siladen Resort & Spa at 17:45, and the sites are usually no more than 20 minutes away. Each snorkeller will be given a high powered torch with a focussed beam, and the guide will carry some too. 

Snorkelling Siladen

Besides joining our scheduled boat excursions, we highly recommend heading off the beach and snorkelling around Siladen. The best way to enter the water in the village close to the main jetty — you can ask the dive centre or reception for help getting there if needed. 

The snorkelling around Siladen is world-class, and often less crowded than many of the sites around Bunaken. The corals here are very healthy, and you can find an unusually high number of anemones and anemone fish. The large seagrass meadow directly in front of the resort is a fascinating area to snorkel, and here you have the best chance of seeing some of the smaller critters up close and personal.
