This great tour in Siargao starts in the morning. We went to marine in General Luna, where we have reserved our boat for our 4-Island tour: Casolian-Island, Naked-Island, Guyam and Daku-Island. If you like to go for snorkeling, don't forget your equipment. If you need some, you can rent on the marine some.
Our favorite island is definitely Casolian-Island, also called Corregidor Island. Arrived on the Casolian-island, you get a tour guide, who is showing you the island. We are hiking through a forest with palms, the grass looks like a green from a golf course, we pass a small village and finally we started a small climb to the hills.
On top, you have an amazing view to the different island surrounded of blue and green water. It is mystique, moment. What is very special: the high grass on the hill makes this moment just more special. A big plus for this island: not many tourists are there.
Naked-Island is also very worth to visit, but very crowded already. The is island build only with sand and is great spot for just relax a bit in the sun and the crystal blue water. Daku-Island and Guysam-Island are nice too, but compare to Corregidor-Island respectively Casolian-Island a bit boring.
