Day 2-4: Land in Puerto Princesa. While the city center doesn’t have much to explore. I would recommend you to go for the 2 famous tours in Puerto Princesa.Honda Bay Island Hopping Tour.This is a full one day tour which includes a visit to a number of islands out of which, Starfish Island, Cowrie Island and Luli Island are great for swimming and snorkeling. The beaches are absolutely spectacular. Even though snorkels are an inclusion in the tour for rent, I would recommend you to buy one. This would give you more opportunities to see breathtaking corals and fishes underwater. Just grab your snorkel and go for a dive!The Underground River Tour. This cave is one of the Seven Wonders of Nature of the World. You’ll be amazed to see how flawless nature is when untouched by man. Go see it for yourself!!
