Yai I Cave

Location : https://maps.app.goo.gl/KrFbJADeX2nTN6em9

Yai I Cave ( also referred to as Tam Yai Ai) is located within the grounds of Saena Sana Priest's Camp Site some 46km north of Chumphon town. Take road No. 3180 out of Chumphon Town. After 21km turn right onto road No. 3201 which forms part of the "Scenic Route".  You will see these signs along the road.

Follow the "Scenic Route" on roads 3201 and 4004. About 7km along the 4004 the turning for the beach is on the right. There is a sign here for New Nordic Coral Beach.

Take this road to the right for 1Km and then turn right again. This roads leads around the hill to the Priest's Camp Site. 

A small sign marks where the steps (about 20) are up to the cave. There is a small building just before the entrance of the cave.

You enter a large chamber which has been made into a place for worship.

Holes in the ceiling bring in natural light to this first chamber. The greens I would guess is from the salty sea air.

The 'Caves & Caving in Thailand' website has referenced this as Cave No. CP0023.

Beside the big green stalagmite is a passageway that connects to a second chamber.

In this second chamber there is a small colony bats.

This cave is right on the sea shore where you can find mangroves growing.
