Lonely Beach

Lonely Beach, locally known as Hat Tha Nam, is a sandy beach on the southwestern coast of Ko Chang Island in Ko Chang District, Trat Province, eastern Thailand. It is known for its long sandy shoreline, palm-fringed setting, and backpacker-oriented atmosphere. The beach is lined with guesthouses, resorts, restaurants and bars, and is notable for swimming, sunsets, and nightlife within the Mu Ko Chang National Park area.

Visitors can expect a long, sandy beach with calm to moderate waves, lined with low-rise resorts, bungalows, restaurants, bars and shops along the main beach road. The beach offers open sea views to the west, ideal for sunset viewing, with areas for swimming, sunbathing and beach walks. The southern end is quieter, while the central and northern sections are more developed with dining and nightlife venues. The surrounding area is hilly and forested.

Originally a small fishing settlement known as Hat Tha Nam, Lonely Beach developed from the late 1990s and 2000s as a backpacker tourism area on Ko Chang, expanding with bungalows, resorts and entertainment venues while remaining within the Mu Ko Chang National Park region.
