What Will You Do There?
Diving, the first thing that you and everyone's priority. As the world's most diversity environment, it such a big regret for you if you not diving. You can learn if you can't dive. Just ask your tour guide and i think they might know the solution. You can also bird watching, expedition around the cave and do many things that unexpected.
How to get there?
From Singapore : Silk Air have a regular flight from Singapore - Manado, then take a regular flight from Manado to Sorong ( with Lion Air or Merpati Air ) to make you easier, its a good idea to call your tour agent.
Outside Singapore and Domestic : Take a flight to Jakarta / Bali ( foreigner tourist) then take a flight to Sorong (with transit in Makassar / Manado )
I'd really hope that this place will be my next journey.
