Location

Tham Long is one of the series of caves in the valley to the north-west of Ban Nam Pua Phatthana. Follow the base of cliff on the west side of the lower entrance of Tham Nan steeply uphill for about 80m to the entrance. In the wet season a large stream resurges from the cave before dropping over a cliff 12m beyond the entrance. Martin Ellis - 12/09/2020

Description

Martin Ellis - 12/09/2020

Immediately inside the draughting entrance the passage lowers to a hands and knees crawl for about 5 m before enlarging to a rift passage approximately 2 m wide and between 5 and 15 m high. This passage meanders for about 100 m heading vaguely west to a sharp turn to the right. Taking this right hand turn the large passage closes down to a draugting crawl. Back at the junction the lefthand passage goes up a series of climbs, which seem to be in re-erroded calcite deposits. Exploration stopped where, on the right, was a climb up a calcite wall 3 or 4 m high. On the left it was possible to climb a similar height into a smaller passage which continued to a squeeze. This would drop back into the passage at the top of the other climb. Looking through the squeeze the passage seems to get bigger. The guides reported that there are about five other, similar caves in the area.
