Known as Koh Hei, Coral Island at Phuket is a beautiful, small island located around three kilometres away from Phuket. It is 2.5 kilometres long with a dense jungle in its centre. It has two main beaches on its northside which are popular with tourists; Banana Beach and Long Beach. On its south side, is the more secluded Freedom Beach.
Spanning 800 metres, Long Beach is the most famous spot on the island and sees many day-trip visitors. There are plenty of deckchairs for rent and sports you can play here. Banana Beach, located to the east of Long Beach and spanning half its length, is a quieter location with fewer crowds. If you're looking to snorkel, Banana Beach is a good spot. It's accessible from Long Beach by a trail that goes through a jungle. However, since the trail has uneven surfaces, it's best to hike here with a good pair of shoes.
If you're up for some exploration and have some time to kill, you can ask your boat driver to head to Freedom Beach on the south side of the island. This small beach is surrounded by steep hills and has a good concentration of coral and marine animals off its shore.
