Our story is a simple one. We love NUSS. The owners were married here and generations of their family have lived and still live here.



Our mission is to provide guests with a unique and memorable experience that will lead them to return to Siladen. We will behave in a socially and environmentally responsible manner, and we are committed to taking an active role in helping develop the local community.

Turtle Sanctuary

In 2004, we launched a conservation program to protect and safeguard the many turtles that call Bunaken Marine Park home. Our staff have been trained by marine biologists to properly handle turtle eggs and manage hatching grounds. To date, 1000s of turtles have hatched and been released through this conservation program. We also support The Turtle Foundation, an international charitable organisation working in sea turtle conservation projects.

Being Green

We are committed to preserving and protecting the environment in which the resort is located. It is only by ensuring that the environment is adequately protected that we can guarantee the long term success of not only Siladen Resort & Spa, but also Bunaken Marine Park.

There is always more that can be done to help preserve this beautiful park, and here is what we currently do:

  • Almost all bulbs throughout the resort are Energy Saving
  • We use Biosolve, a bacteria-based cleaning product which eats grease and converts it into carbon dioxide
  • We use glass reusable straws for drinks
  • We avoid the use of plastic bags and water bottles
  • We are constantly working on various projects to improve our energy efficiency and reduce our environmental footprint.

Environment Preservation

As part of our efforts to preserve the marine environment, we have installed mooring buoys to allow boats to anchor safely, without damaging the coral reef. Our staff are forbidden from using boating practices that may cause damage to the coral reef, and guests diving with Siladen Resort & Spa must sign the NSWA code of practice.

We organise regular PADI Project AWARE activities and World Ocean day activities, and we invite the local children to be part of these projects.

Siladen Resort & Spa is an active member of the North Sulawesi Water-sports Association (NSWA), regularly appearing at meetings and participating in all organised activities. These include Eco Reef and BioRock installations, Crown of Thorn clean-ups, release of illegally fished Napoleons, and most important of all, keeping an eye on others who also use the park, reporting any harmful or illegal activities.

Siladen’s Domestic Animals

Like many places throughout the developing world, stray domesticated animals such as dogs and cats can pose a problem if left unchecked. We invite the local veterinary team to the island for yearly vaccinations and sterilisation of stray animals. Local residents are also welcome to have their pets vaccinated and sterilised, free of charge.

The resort pays for all transportation and sterilisation costs, while the vaccines are donated by the veterinary teams.


Waste is a major problem in all developing nations. We pursue a policy committed to reducing waste at the Resort to a minimum. To avoid all single use plastic bottles, we have installed 19 litre reusable drinking bottles in each guest villa, plus all common areas of the resort. All guests receive their own Siladen drinking bottle upon arrival, which they can refill from any water source throughout the resort.

All other drinks are either served in cans or glass containers, which can be sent for recycling. Organic waste from the kitchen is either composted, or given to the villagers to feed local animals.

We have also installed rubbish bins throughout the island, and it is regularly delivered to a location close to the resort where we can help send it to Manado.

Some of our Waste Management efforts are:

We pay the villagers to regularly clean the beaches of Siladen island and we help them sending the non-organic waste to Manado.

We organise regular clean ups with the help of the local school children and we give short presentations regarding the importance of looking after the environment.


We are committed to preserving the original vegetation of the island. We have therefore embarked on a long term landscaping effort aimed at continuously improving the attractiveness of the Resort and its surroundings.

Water Management

Due to a shortage of water on Siladen during the dry season, we have installed desalination plants for the resort so we do not negatively impact the islands fresh water supply.

We have also installed water capturing systems on most of our buildings, which will capture and divert rain water to our reservoirs. We also capture drainage water from air conditioning systems, which we use on our plants and herb garden.
