What is the best island tours in Thailand?
Phuket is the largest island(or peninsular) in southern Thailand. It has something suitable for any budget and taste, with a variety of dining and party options and hundreds of hotels to choose from. In addition to visiting the magical attractions of Thailand's largest island, you can also take a speedboat to many nearby tropical paradise, including the famous Koh Phi Phi, Koh Sok National Park or enjoy a quiet cruise ship around the mysterious Phang Nga Bay.
Koh Samui is a cosmopolitan melting pot, attracting budget and young travelers flood in and leave in waves each month. Not only because it's natural views, but also for the Full Moon Party in the nearby Koh Phangan.
Koh Similan is one of the most famous islands in the Andaman Sea. They are famous for their top diving sites and pristine beaches. The park is closed down for the public in the monsoon season, from May to October, every year to protect the fragile and unique eco systems on the Islands.
Is Krabi or Phuket better?
Both of them are superb southern Thailand destinations. If you want a sophisticated vacation in a well-developed and convenient destination, then Phuket is better. Almost all island hopping, city sightseeing activities and international airlines is easily accessible if staying in Phuket. Offer more options for all level visitors.
In contrast, the Krabi is better if you want to relax in or surrounded by a real natural environment. Krabi Island is a typical leisure place with miles of beautiful beaches and jungle covered with mainland, caves, waterfalls, rainforest and wild animals. The Krabi may be a relatively new area of tourism, but it is developing rapidly.
It's understandable that both are on your bucket lists for good reasons. If you have time to a complete southern Thailand tour, you can absolutely visit them all!
Can I only stay in beach and island and not visiting Bangkok?
Yes, you can. The round-way flight from and to Phuket airport will save a lot compared with Bangkok inbound and Phuket outbound.
