About Phraya Nakhon Cave
This is one of the most iconic cave scenes in Thailand, and it lives up to the photos. A vast collapsed limestone cavern lets daylight pour through a natural skylight onto the ornate Kuha Karuhas royal pavilion, built for King Rama V. When the light beam hits the pavilion, it is genuinely spectacular and well worth the effort.
And effort is the operative word. Getting here means driving to Bang Pu, then either a boat ride or a steep headland walk to Laem Sala Beach, followed by a steep uphill climb to the cave itself. In tropical heat that climb is the real catch, so this is not a casual stroll.
Come prepared: bring water and decent shoes, and time your arrival for late morning so you catch the sunbeam through the skylight. The dry season makes the access easier.
