Cyber Waterfall

Cyber Waterfall — also called Namtok Hin Lat — flows down from the Huai Kha Khaeng hills in Huai Khot district, Uthai Thani, inside the Huai Kha Khaeng Wildlife Sanctuary, a UNESCO World Heritage Site. Entry is free but access is controlled by the sanctuary; the waterfall lies roughly 86 km from Uthai Thani town, well off the main road network.

The English name comes from Ban Cyber, a nearby village; the “Hin Lat” name (flat rock) describes the lower falls, where water spreads across broad, sloping rock shelves rather than dropping over a single cliff. Upstream, the flow is known as Namtok Loi Choi before it reaches these lower shelves — together they form a multi-tiered cascade running through forest rather than one dramatic drop.

Water volume swings hard with the season. September through early November is the fullest window, when the pools below the rock shelves run deep enough to sit in; by the dry months the flow thins to a trickle over bare stone. The last stretch in — a roughly 900-metre walk after several kilometres of unpaved, rock-strewn track — floods out completely during the August-October rains, when only high-clearance 4x4 vehicles can get close.

Watch out: The sanctuary has closed Cyber Waterfall outright more than once — for flash-flood risk after heavy rain, and separately after wild elephants were spotted near the trail. Both closures were open-ended rather than announced in advance, and a fatal drowning has also been recorded here. Confirm the waterfall is open and get permission from the Huai Kha Khaeng Wildlife Sanctuary office before setting out; don’t assume access based on an old blog post or map listing.

Insider Tip: Call ahead rather than showing up — the access road alone rules out a same-day change of plan if the sanctuary turns you away, and mobile signal thins out well before the falls.

Because this sits inside a protected wildlife sanctuary rather than a developed park, facilities are minimal: basic accommodation exists for permit-holding overnight visitors, but there’s no food service on site, so bring your own water and supplies. Wildlife sign, including elephant tracks, is part of what makes the sanctuary significant — and part of why access stays restricted around the waterfall.

Treat the rocks as slippery year-round and the current as unpredictable after rain. If the sanctuary grants access, stick to the marked pools rather than pushing further upstream, and follow any instructions from the rangers on site.
