Koh Chang, known as Elephant Island, is one of Thailand's largest islands and a jewel in the province of Trat. It is renowned for its dense jungle, steep hills, and beautiful waterfalls, as well as its white sandy beaches and clear blue waters. The island is part of the Mu Ko Chang National Park, which preserves much of its natural beauty. Visitors to Koh Chang can enjoy a range of activities from snorkeling and diving to explore the vibrant coral reefs, to trekking in the jungle and discovering hidden waterfalls. The island's west coast is lined with beach resorts, bungalows, and restaurants catering to tourists, while the east coast remains more tranquil and less developed, offering a glimpse of the island's traditional way of life. Koh Chang has a laid-back atmosphere, with a nightlife that is lively but not as intense as in Thailand's more famous beach destinations. The island is also a gateway to smaller, less-visited islands nearby, making it a perfect base for island hopping.
