Central Thailand’s trekking is built around two of the country’s most-visited national parks, both an easy drive or train ride from Bangkok. Kanchanaburi province’s Erawan National Park is known for its seven-tiered turquoise waterfall, reached via a moderate forest trail that climbs alongside the cascade, while Khao Yai — one of Southeast Asia’s oldest national parks and a UNESCO World Heritage Site — combines grassland, deciduous, and evergreen forest across a much larger and wilder trekking area.
Compared to the north’s multi-day village treks, central Thailand’s routes are generally single-day or short overnight walks, making the region well suited to travellers combining a Bangkok visit with a shorter jungle excursion. Wildlife is a highlight in both parks: Khao Yai holds wild elephants, gibbons, hornbills, and (rarely sighted) tigers, and both parks are best visited in the cool, dry season from November to February, when trails are firm and waterfall flow is still strong from the tail end of the monsoon.
