The name 'Tham Phang' translates to 'Collapsed Cave,' referring to the eroded karst formations surrounding the cove.
During the reign of King Rama V, Ko Sichang served as a summer retreat, and the royal family frequently visited this specific beach area.
The beach is unique on the island for having a crescent-shaped bay that protects bathers from the stronger currents of the Gulf of Thailand.
The area hosts a variety of macro-algae and small rock pool crustaceans due to the presence of volcanic rock along the waterline.
Hat Tham Phang is the primary swimming beach on Ko Sichang, located on the island's western coastline. The cove is sheltered by natural rock formations, creating calm, swimmable waters throughout much of the year. The beachfront is densely lined with wooden structures housing local seafood vendors and open-air restaurants. It is one of the few locations on the island where public swimming is permitted. The beach area features a mix of sand and rocky outcrops that are submerged at high tide. Local amenities include beach chair rentals and basic public facilities.

Bring water shoes to navigate the rocky sections of the shoreline safely.
Visit on weekdays to avoid the high density of weekend visitors from the mainland.
Order fresh squid or local blue crab directly from the beachside kitchens.
Avoid swimming during heavy monsoon rain, as runoff can affect water clarity and safety.
Maintain modest swimwear when walking away from the immediate beach sand toward the dining areas; do not litter in the cove.
