After hotel pick-up in the early hours, head to the first stop on the trek at the Kilometer 30 viewing point at Thanarat Road. Capture the scenery of the Northern part of Khao Yai National Park, great for photo opportunities. Trek onward to Kilometer 33, known as Nong Park Chi to the locals. Walk for around 2 hours, passing an observation tower and many different species of wildlife. Savor a traditional Thai lunch at a local restaurant. After lunch, head to the Khao Yai National Park Visitor Center in the park headquarters, a useful starting point for visitors with information and interpretive facilities to enhance your appreciation of the park. Finally, stop at the splendid Haew Suwat Waterfall, with plenty of shady tree spots to sit under and many large rocks to lie down on and relax. This stunning waterfall was made famous in The Beach, but is unfortunately off limits to swim in. Overnight in Khaoyai
