In southern Thailand, Khao Sok National Park is home to one of Earth's oldest tropical evergreen rainforests.

Clocking in at a jaw-dropping 160 million years (yes, you read it right!), this ecosystem is older than the Amazon and the forests of Central America!

Its rich biodiversity and prehistoric charm make it a must-visit for nature lovers and adventure seekers alike. Perfectly preserved through the Ice Age, this natural haven is a lush, verdant paradise waiting to be explored.

What Makes Khao Sok So Special?

Imagine stepping into a rainforest untouched by millennia. Khao Sok’s incredible biodiversity includes majestic elephants, playful gibbons, and the elusive Malayan tapir. You might even stumble upon the world’s largest flower, the Rafflesia kerrii, with blooms that can reach up to 80 centimeters in diameter. If you’re lucky, it won’t be during its “fragrant” rotting-flesh phase! The park also offers serene lakes, towering limestone cliffs, and tranquil floating bungalows for a unique overnight experience.

How Did It Survive for So Long?

While other parts of the planet froze during the Ice Age, Khao Sok’s location shielded it from the harshest climates, allowing its ecosystem to flourish. After the ice melted, rainfall and lush vegetation created a paradise of greenery. This untouched history contributes to its status as one of the most ancient rainforests globally, where time feels like it stood still.

Khao Sok’s Geological and Cultural Legacy

The region’s towering limestone karsts date back over 250 million years to when the area was submerged under an ancient sea. These majestic cliffs, now draped in green, stand as testaments to Earth’s evolving landscapes. The monolithic structures dominate the horizon, forming a breathtaking backdrop to the park’s trails and waterways. Additionally, ancient human activity has been documented in the area, with evidence suggesting that early communities thrived here thousands of years ago, coexisting with the lush environment​.

What Can You Do There?

Khao Sok offers activities for every kind of explorer. Kayak through the glassy waters of Cheow Lan Lake, trek deep into the jungle for breathtaking views, or take a peaceful morning safari to spot wildlife at its liveliest. For those who prefer to relax, the park’s floating accommodations allow you to wake up to the sound of nature in serene surroundings.

How to Get There Without a Time Machine

While you can’t fly directly to Khao Sok, it’s accessible from nearby hubs like Surat Thani, Phuket, and Krabi. For a more immersive journey, consider booking a multi-day tour that includes transportation and guided explorations. Self-guided trips are also an option; just prepare for a bit of planning to navigate the routes and boat transfers.

A Living Reminder of Earth's Resilience

The rainforest of Khao Sok holds vital lessons about nature’s adaptability and resilience. For millions of years, it has survived natural disasters, climatic shifts, and human development. Despite being affected by logging in the mid-20th century, the region rebounded through conservation efforts, becoming a protected national park in 1980. This designation has allowed its flora and fauna to recover, including endangered species such as the Asian elephant and clouded leopard. Today, Khao Sok stands as a living relic and a beacon of hope for conservationists worldwide​.

Khao Sok’s rainforest can be considered a journey into Earth’s ancient past.
