  6. gameda samsodien says

    Had a month long holiday in thailand (ko samui,phuket.pattaya and bangkok) my 3rd time in thailand,and would love to do more island…just love the beaches!

  7. says

    I lived in Koh Phangan last winter and I highly recommend it. Stay away from Haad Rin and all the drunken backpackers there. The northwest coast is much more laid back.

  8. says

    Out of the ten islands selected (and I have been to most of them) I would no doubt choose Koh Lipe, for it is the smallest and quietest of them all and, while not in high season, is an oasis of calm and relax.

    However, I would add another small island not included in the list that is not very well known but, for me, is one of the most beautiful and enjoyable islands of Thailand: Koh Mak. See my impressions and pictures from the island at my blog:

  9. Pam says

    1.Koh Mun Nok is a private island with only one resort. We love it there , very peacefule, sparkling clear water , nice beach. It s a good place for people who just want a peacefule place to just so nothing but enjoy the nature. Koh Mun Nok is in the central part of Thailand. Take a boat off Rayong.
    2. Koh Ta Chai is a virgin island in the south. It is a allowed only for day trip.
    3. Koh Kood is also on top
    Of the list to visit. It is less touristic place than Koh Chang. Beautiful beaches and peaceful.

  10. Jordan says

    I’m traveling over to Thailand for 3 weeks in July. Can somebody email me the best route to take & the best time to spend on each Island? First 3 nights are in Bangkok, last 4 nights are in Koh Phangan due to the full moon party being our 2nd last night! It would be greatly appreciated!

  11. Linda says

    Having spent three weeks in Thailand with a week to go having been to Chang mai for elephant nature park which was excellent purely for the conservation and rescue of elephants not for riding or tricks. It was brilliant would highly recommend it with an overnight stay. I have to say that Phuket was very disappointing very crowded and not my cup of tea but when arriving at phi phi don was blown away staying on beach in a bamboo bungalow it was paradise. Leaving there for ko lanta but feel it is not in the same league and we are searching for the same type of paradise island to spend our last few days before we fly from Krabi on 19th march. Any suggestions???

  12. says

    @Linda, Though not an island, Railay (Rai Leh) near Krabi is also very beautiful. It’s only accessible by boat so it has a bit of an island feeling.

  13. Jackie says

    My husband and I are going to Thailand in November, I wondered if anyone could tell me if you can actually visit phi phi from koh samui?
