There are two ways to get to Ko Nang Yuan: via boat taxi from Ko Tao, or via a snorkelling day trip from Ko Tao or further afield.

Longtail boat taxis from Ko Tao will quote you 600 baht return (March 2022), but you may be able to bargain them down. You pay half the money when you arrive and the other half when they pick you up at the agreed-upon time.

Snorkelling day trips from Ko Tao start at 250 baht per person including the round trip. It is also possible to come here for a snorkelling day trip from Ko Samui for about 1,200 baht, though this is of questionable value considering that while the trip may take the whole day you are likely to spend only an hour here. If you are really interested in visiting here, stay at least one night on Ko Tao.

Visitors to Ko Nang Yuan must pay a 200 baht fee (waived if you stay overnight).

Plastic bottles and cans are banned from the island. Buy water and other drinks in glass bottles in Ko Tao to avoid paying inflated prices on Ko Nang Yuan.
