Instead of relaxing on the sand, snorkeling is certainly a must to do. You can observe different species in the water between reefs.
If you wish to come in the morning, this is when the beach is the coolest, in the light shadow of trees. Restaurants and bars are nearby to refresh yourselves if you prefer to stay a while.
The access is not the easiest, however, your effort worth it! Crystal clear water and pristine white sand is what you will find after descending the hill. However, be careful, on your way back, you will certainly be exhausted. You are also able to access from Patong Beach by Long Tail Boat which is highly recommended if you are not fit enough.
By walk, the price is THB 200 per person. This price is to cross the private land from the main road to the beach.
To park your motorbike, there will be an extra cost of THB 100.
By boat from Patong Beach, count from THB 1,000 but this price may differ according to the number of people, seasonality.
