KOH WUA TA LAP
Anchor in 8 metres on a muddy bottom – or preferably pick up an available mooring – on the northeast side of the island. Approach from the north or east, giving Koh Phi plenty of clearance to avoid underwater reefs.
If you feel like a hike, a 45-minute easy climb up 345 steps takes you to a viewpoint overlooking the islands. Proper shoes and water are a must! South of the main beach is a huge cave; keep an eye open for wild monkeys and bats.
Since this (often referred to as Koh Ang Thong on tourist maps) is the main island in the group, the National Park HQ has some bungalows, a restaurant and small shop; there’s a fee of 500 baht each to enter the National Park.
Rocks in the water
Heading north from Koh Wua Ta Lap to Koh Mae Ko, north of the southern-most beach, there is a coral head right in the middle of the passage. It is possible to pass on either side of this.
