Hellfire Pass Memorial

In the hills west of Kanchanaburi, a corridor of raw rock slices through the forest. Hellfire Pass (Konyu Cutting) is the deepest and most infamous section of the Thailand–Burma “Death Railway,” built in 1943 by Allied prisoners of war and conscripted Asian labourers for the Japanese military.

Why It’s Interesting

The cutting was dug almost entirely by hand — hammer, tap, and basket — by starving, sick men working around the clock; the flicker of torchlight on the rock faces at night gave the pass its name. Thousands died here. Today an excellent, Australian-government-run memorial museum tells their story with restraint and care, and a forest trail follows the former trackbed past the great cutting. It is one of the most affecting historical sites in Southeast Asia.

Best Time to Visit

Open all year, but the exposed trail is hot; the cool, dry season (November–February) is much kinder for the walk.

Getting There

It’s on Highway 323 in Sai Yok district. You can ride the surviving railway to Nam Tok, but reaching the pass itself is simplest by car or organised tour from Kanchanaburi.
