Just returned from an 11 night stay at the Kantary Bay Hotel. All the staff were great and always very helpful. While the hotel is in quite a secluded location a shuttle bus service runs to local towns for reasonable prices if you want to escape the quietness for a while.
The beach at Cape Panwa is excellent and a great facility to be able to use.
I would highly recommend this hotel if you are looking for a beautiful and secluded part of Thailand!
Many thanks to Kantary BayMore
