This was a fantastic beach to visit. Parking is free in a dirt lot just outside the gate to the Anse Chastanet Resort. You walk in through the resort main road and just before you hit the main bar building stay to the right. Keep walking in and to the right and you will get on the resort beach. Walk to the end and you will see a path that turns into an access road. Walk down the access road until you hit another beach and you see the large ocean rock. The further down the beach you go the more outside of the resort banter you will be.
If anyone from the resort stops you and tells you to pay money, just tell them you are looking for the Anse Mamin beach. If you don't use their services, foods, bar, chairs, you DON'T have to pay anything. Just keep saying " we are trying to get to the beach only" This seems to bail us out of a lot of resort interactions, both here and other places around the island.
Snokeling in general is not great in St. Lucia, so don't expect a lot. The water, sand, and waves were all perfect here. The road down to the resort lot, like many places is an engineering feat.
