Kaeng Chet Khwae National Park

Kaeng Chet Khwae — “seven rapids” — is a run of named rapids along the Khwae Noi river system in Wat Bot district, part of the wider Kaeng Noi National Park territory that stretches across Wat Bot, Chat Trakan, Nakhon Thai, and Wang Thong districts of Phitsanulok province. The named rapids include Kaeng Kannanoi, Kaeng Chet Khwae itself, Kaeng Chon, and Kaeng Tao Lek, with waterfalls such as Santhakian in the surrounding forest. This is a Department of National Parks fee site, not a free attraction: entry runs 100 THB for foreign adults (50 THB for children) and 20 THB for Thai adults (10 THB for children).

Trails follow the riverbank between the rapids, giving multiple vantage points over the water as it channels through the rock. The park’s activity list runs beyond a simple walk-and-look stop — rafting, kayaking, and community-based tours are organised through the local park unit, alongside straightforward hiking and waterfall visits. Rangers recommend July, September, and November as the strongest months for a visit, when the rapids run fuller and the forest stays cool enough for camping; November to February is drier and more comfortable for hiking, though the water itself calms down by then.

Insider Tip: Call the park office (055 316 605) before a rainy-season visit to check the rapids are running safely — river levels here can rise fast after heavy rain upstream.

Watch out: Swimming isn’t recommended — the channels between the rocks carry a strong current, and there’s no lifeguard or marked swimming zone. Stick to the riverbank trails and viewpoints.

The park entrance sits off the road through Wat Bot district; driving or riding is more practical than relying on public transport, since bus services don’t run directly to the gate. Bring water, snacks, and shoes with good grip for the rock surfaces near the rapids, which get slippery when wet. Mobile signal is patchy but workable (3G coverage reported) around the main visitor areas.
