From Manila, drive north to Dasol in Pangasinan. There is a 20km rough road from Dasol to the fishing village in Tambobong. From there you can get an outrigger boat to take you to Crocodile Island.
Nalasin in local dialect means "something that separates". Its a narrow and shallow rock filled channel between Crocodile Island and Kabakungan Cove. Its facing west and the rock formations there are perfect for sunset shots.
