  • You MUST have your own insurance (health, social, company, etc.) to be able join.
  • We made this trip very cheap due to the financial support we will receive from the government after the trip for helping the local economy recover (by bringing tourists to the island) from the natural disaster occurred in October 2013. The casualty numbers were about 40 deaths and 80 houses were half or completely destroyed. It was caused by the large scale typhoon and following landslide.
