Khung Sai Beach has earned the nickname "The Hidden Beach" of Pranburi because it is not situated next to the main road and requires an on-foot journey for access from the Khao Kalok or Thao Ko Sa Forest Park area. This beach is located on the northern side of Khao Kalok, stretching for approximately 1 kilometer, and is differentiated from other Pranburi beaches by its striking geological features. The beach features soft, white sand nestled within a cove and the seawater here is often clear and calm, making it a destination for those seeking to escape the crowds of more popular beaches.

The primary unique feature that makes Khung Sai Beach appealing is the stretch of reddish-brown or orange rock cliffs lining the shore. These cliffs have unusual shapes, formed by natural erosion, and contain small caves or rock crevices that tourists can explore and photograph. The challenge of accessing the beach ensures that it maintains a high degree of natural preservation. Visitors who complete the hike are rewarded with the feeling of owning a private beach, complete with a stunning view of mountains and the sea coexisting beautifully.

The main activities at Khung Sai Beach include exploring the shoreline, taking photos of the unique landscape, and relaxing with a picnic. Accessing the beach requires hiking up and down a hill for approximately 1 kilometer, which takes about 25–30 minutes. Visitors should be physically prepared as the trail has steep sections and some sharp rocks. The atmosphere at this beach is very simple, focusing on experiencing nature authentically, as there are very few amenities. Relaxation here is quiet and highly private.

Khung Sai Beach is highly appealing to adventurers and hiking enthusiasts looking for a minor challenge before reaching a beautiful reward. Landscape and fashion photographers love the striking contrast of the reddish-orange cliffs against the turquoise sea and sky, which creates a unique backdrop. It is an ideal spot for couples or small groups of friends who are looking for a place for exploratory relaxation and maximum tranquility.
