A shuttle bus to Nai Harn Beach is available and local restaurants at Rawai offering authentic Thai food with offerings like fresh seafood which you purchase and get local restaurants to cook for you at special price.
Coral island across the water is just a 15-20min boat ride. There are plenty of transport options around 1800 baht to be taken out for day private trip in a longtail boat.
The resort Chef amazingly did a Thai cooking class for us. He was very hands on ensuring you weren’t left behind.
We highly recommend this resort, don’t let people talk you out of it being too far away, if you’re done with Patong, this place is all about relaxing and quiet.
