Vajiralongkorn Dam (Khao Laem Dam), Kanchanaburi

Thailand’s third-largest reservoir transforms the rugged landscape of western Kanchanaburi into an expansive aquatic wonderland stretching deep into Myanmar’s borderlands. Vajiralongkorn Dam creates a massive lake that floods ancient valleys, leaving dramatic limestone peaks and forested hills rising like islands from emerald waters. This engineering marvel serves multiple purposes—flood control, irrigation, and hydroelectric power—while inadvertently creating one of Thailand’s most scenic inland water bodies.

Boat tours reveal the reservoir’s most captivating features, including the famous sunken temple whose spire still pierces the water’s surface during dry season. Long-tail boats weave between flooded tree tops and navigate channels that lead to floating restaurants serving fresh fish curry and som tam. The surrounding hills offer hiking trails with panoramic viewpoints overlooking the vast expanse, while fishing enthusiasts cast lines for giant snakehead and catfish. Early morning brings flocks of hornbills and kingfishers diving for breakfast, their calls echoing across the still water mixed with the gentle puttering of fishing boats.

Tranquility defines the reservoir experience, where city noise gives way to lapping water and rustling leaves. The scale feels almost overwhelming—endless blue stretching toward Myanmar’s mountains creates a sense of wilderness rarely found in Thailand’s busier regions. Floating bamboo houses dot quiet coves, and local fishermen wave as they check their nets, maintaining rhythms unchanged for generations despite the transformed landscape.

Cool season visits from November through February offer the clearest views and most comfortable temperatures for boat excursions. The reservoir lies about three hours from Bangkok via Kanchanaburi town, with local transport available to the dam area. Bring sun protection, water, and a camera with extra batteries—the remote location means limited facilities. This remarkable fusion of human engineering and natural beauty provides a peaceful alternative to Thailand’s crowded beaches and temples.
