The blow holes are quite cool. Long drive out there though. Be careful (as others have commented) of the old man that may ask you for up to 50tala each to throw coconuts into the blowholes! We went with an organised tour so just got the standard charge (10tala I think). Just drive past the old man! If it was a reasonable $1/ coconut then I would say do it- but he is exploiting the attraction to the max! Also take plenty if hand sanitiser for the toilet!
