Above the Sanbanggulsa temple, up steps through the trees that cover the lower slopes of Sanbangsan, is a cave which is home to a small Buddhist grotto. A statue of the Buddha sits on a platform at the back of the cave, with candles and offerings placed by visitors. A stone trough has been placed under the steady drip of water from the roof in front of the Buddha with ladles to allow people to drink. A monk, wearing the grey of Korean Buddhists, was chanting and striking his moktak (hollow percussion instrument) when I visited a couple of days ago.
The location is quite something, with the rock face of Sanbangsan high above and views southwards over the coast to the islands beyond.
