First off, I knew I wanted to go to places that had nice beaches, good food, and with the least amount of people. I was looking for intimate islands in Thailand. I made some mistakes but also some good choices. Hope my little photo guide helps you in your trip:
Island 1. Kata, Phuket. Loved this places because it is a lot less touristy than Patong (which is only 15 mins away by car). Kata is a small beach town, with great food joints, cafes, good hotels, and a nice central beach. What I loved about Kata was you can walk everywhere and don't need a taxi or tuk-tuk. One of our favorite spots here was O-Oh Coffee house (great matcha lattes). Def would recommend going. Hotel, The Chaba House
Island 2. Ko Phi Phi. One of the best islands for the beach in my opinion. However, here are the pros and cons. The pros being that island is divided into 2 parts. The party side, and the calmer side. The beaches of Ko Phi Phi are blue blue blue. Maya Beach (The Beach) is really close to visit and though it's super touristy, def worth a visit for the beauty alone. Ko Phi Phi is great for visiting other bordering islands and to enjoy the beach and nightlife. The cons, it's touristy, and if you are staying on the party side of the island, you won't sleep until 2am when the music stops so make sure to check with your hotel for the noise level. Also, the center of the island is filled with shops so make sure you walk around to the authentic parts. Make sure to do the viewpoint hike to the top to watch the sunset. I would 100 percent recommend going to Ko Phi Phi only if you choose your hotel wisely. Hotel, Sunwaree Phi Phi Resort. Highly rec this place for the views, the private taxi boat, the staff, the rooms, but it's on the party side so you have tons on noise until 2am.
Island 3. Best and Favorite island so far. Railay Beach . This has to be hands down one of the most beautiful, intimate, clean, and delicious islands I've been on. No other island has come close to the charm of this place. I would recommend 3 nights here. So much to do; rock climbing, snorkeling, island hoping, cool nightlife, great food (def try the Thai burritos at One Stop Take Away Shop) and Tew Lay Bar. Hotel, Railay Phutawan Resort, highly highly recommend!!
