Kiwicom asked about this under the heading about best way to get to Hua Hin, but it may be of interest to others visiting the area who also would love a couple of days on a quiet tropical island with swaying palm trees and do snorkeling near Hua Hin
Koh Talu Island is a very small island, just a short boat ride from the mainland coast at Bang Saphan. That is about 2 and a half hours south of Hua Hin.
Koh Talu is a real 'get away from it all' place, don't expect shops or any entertainment at all, but for many that is the beauty of the place. A very small island.
If you want a couple of days snorkeling near Hua Hin and prefer not to do it as a day trip, then a couple of nights is for pure relaxing, snorkleing, messing around on the beach. Take walk and find a quiet spot !
I would say 2 nights sufficient, but to add that for those spending a couple of weeks in Hua hin / Cha Am it is really worth going for either the day trip, or better still a couple of nights - at least you will have been on a small Thai island !
The resort does 3 day/2 night packages with full board, snorkeling etc, quite a good deal. The package includes boat trip, if not taking their 3 day 2 night packages the resort also does a 7 am pick-up from the Clock Tower in Hua Hin at B 250 per person each way
Lots of photos here:
You can call Koh Talu 'undiscovered', although people venture there it is quite a 'secret' - good for spotting it !
Just a couple of hours and then a short boat ride, I would highly recommend a couple of days for anyone spending say more than 7 days in the Hua Hin area.
Or at least do the day trip - all the tours agents offer the trip.
