I've been a few times now and fall more and more in love with it. Great surfing for all levels, beautiful mangroves and a cool coastal cruise on your motorbike.
Plenty of little resorts, but its not overcrowded. I've spent many a night listening to the pacific ocean waves hitting the nearby reefs, supping a cold beer next to a beach fire, and looking up at a crystal clear starry night's sky. Awesome spot. I got the feel of more southern pacific island but without the long flights to get to.
I interviewed several resort owners and it appears that there is a surfing season that spans from the fall through the spring with a flat summer.
The primo season is said to be October through November however there are surfing competitions that occur in the month of May. There are a myriad of surfing spots for any swell and crowds seemed minimal compared to Aus, Hawaii or California. Most of the surfers were international guests although the Filipinos are beginning to culture their own class of international competitors. Fishing appears that it will vary by season according to the migration patterns of pelagic species of fish. It appears that good numbers of Mahi Mahi, Wahoo, Yellowfin Tuna, Sailfish and Marlin migrate through the area given the nature of the Philippine Trench that fronts the island. The Philippine Trench is a submarine trench to the east of the Philippines which has a length of approximately 1,320 km (820 mi) and a width of about 30 km (19 mi) trending southeast. Its deepest point, the Galathea Depth, has a depth of 10,540 metres (5,760 fathoms; 34,580 feet), the third deepest in the world (wiki). Siargao seems like a perfect place for relaxing, surfing, fishing as well as island tours. jalias
For adventure-backpackers, one of the best islands to visit! For the surfing, island hopping with very unique attractions (stingless jellyfish, caves and cliff dives, etc) the locals are very friendly and accomodating!
Siargao is a nice little island which does offer white sand beach with clear blue water. Most part of the island is still unexplored and paradise for the surfers.
It is a very beautiful place. It has a very untouched feeling and the people are very friendly. It is place with not a lot to do so be prepared to have a slow paced feel.
