Srinagarind Dam

This section is being updated and will be available shortly.

Srinagarind Dam is a major rockfill hydroelectric dam on the Khwae Yai River in Si Sawat district of Kanchanaburi province, named in honour of the Princess Mother. Its vast reservoir, one of Thailand's largest, spreads emerald water among forested hills and islands, forming the gateway to Khuean Srinagarindra National Park and the region's raft-house lake country.

The dam crest and surrounding viewpoints deliver sweeping panoramas over a sea of green water and jungle-clad hills, and the reservoir behind it has become a playground of floating raft resorts. It pairs naturally with Erawan National Park nearby, adding an easy scenic stop to Kanchanaburi's classic waterfall day.

The view from the dam crest across the immense reservoir is the headline, especially in late-afternoon light. Landscaped grounds and viewpoints, the engineering scale of the rockfill wall, boat trips among drowned valleys and islands, and floating raft houses moored in quiet coves define the experience.

Drive or stroll the dam crest for photographs, visit the landscaped parkland below, and charter a long-tail or join a raft-house stay to explore the reservoir's coves. Fishing trips, kayaking from lake resorts, and combining the dam with Erawan Falls or Huai Mae Khamin across the water fill an itinerary easily.

The crest viewpoint over the reservoir is essential, with the contrast between the massive engineered wall and the drowned wilderness behind it the site's defining image. A boat ride into the lake's island scatter, or at least a raft restaurant lunch on the water, completes the visit.

Coves deep in the reservoir hide waterfalls that drop straight into the lake and raft houses reachable only by boat, where nights pass in total stillness. Early morning mist on the water, seen from a lakeside campsite or raft deck, is a scene most day visitors to the dam never witness.

The dam is named for Princess Srinagarindra, the revered Princess Mother, and Thai visitors treat the site with corresponding respect. Lakeside communities resettled when the valley flooded maintain fishing and orchard livelihoods, and their easygoing raft hospitality carries the region's river culture onto the reservoir.

The reservoir laps against Khuean Srinagarindra National Park's forests, where hornbills, gibbons and deer inhabit the hills above the waterline. Islands, drowned valleys and tributary arms invite exploration by boat, and the surrounding karst and woodland glow green through the rainy months.

Families enjoy the easy crest viewpoints, spacious grounds and the adventure of raft-house stays, where swimming platforms and kayaks keep children busy for days. Life jackets are standard on boats and rafts, and the gentle pace of lake life suits multigenerational Thai-style group trips especially well.

Evenings on the reservoir mean dinner on a raft deck, karaoke at some Thai-oriented floating resorts, and skies dense with stars; the dam area itself is quiet after dark. Anyone seeking bars or markets must return to Kanchanaburi town, roughly an hour and a half away.

Shoot the reservoir panorama from the crest in the soft hours, the geometric sweep of the rockfill wall from the lower viewpoints, and island-studded water from any boat. Mist at dawn and the gold of late afternoon are the lake's best moods; drones may face restrictions near dam infrastructure, so ask first.

Completed in around 1980 by the national electricity utility, Srinagarind Dam was among Thailand's largest hydropower projects, taming the Khwae Yai and flooding a vast forested valley. Named for the Princess Mother, it reshaped the province, creating the reservoir that now underpins Si Sawat's lake tourism and feeding water and power to the region.

Si Sawat district blends resettled valley communities, lake fishermen and orchard farmers, with a measured rural pace. Reverence for the monarchy, visible in the dam's dedication, runs deep, and visitors who show quiet respect at memorial features and wai-greeting courtesy find the lakeside communities notably welcoming.

November to February offers cool, clear conditions and the most comfortable raft-house nights, while the reservoir stands fullest late in and just after the rains. Late afternoon flatters the crest views year-round, and weekdays keep the viewpoints and lake resorts pleasantly uncrowded.

The lake district follows Kanchanaburi's pattern: hot and hazy from March to May, green and showery from June to October, dry and mild from November to February. Water levels vary with the seasons, subtly changing shorelines, and cool-season mornings can bring beautiful mist over the reservoir.

The dam area hosts occasional utility open events, while surrounding towns celebrate the national calendar, with Loy Krathong in November especially pretty on the water. Thai long weekends fill the lake's raft resorts, so book ahead if travel coincides with public holidays.

Combine the dam with Erawan National Park: waterfall hike in the morning, then the crest viewpoints and a late raft-restaurant lunch on the reservoir. With more time, transfer by long-tail to a floating resort for a night on the water, returning next day via lakeside viewpoints and orchard stalls.

An hour or two suffices for the dam viewpoints themselves, making it an easy add-on to an Erawan day. The reservoir deserves longer: an overnight raft stay, or two days if venturing across to Huai Mae Khamin waterfall, unlocks what the lake district really offers.

The dam lies roughly 70 kilometres from Kanchanaburi town by good sealed road, about an hour and a half's drive, shortly beyond the Erawan National Park turn-off. Hired cars, tours and songthaew charters are the practical options, as regular public transport to the dam itself is sparse.

A vehicle covers the crest road, viewpoints and parkland easily, while everything beyond the shoreline moves by long-tail boat from the piers serving raft resorts and lake excursions. Walking suffices within the landscaped dam grounds; distances around the wider reservoir are deceptively large.

Songthaews and buses from Kanchanaburi serve the Erawan park area near the dam approach, but the final leg usually needs chartered transport. Kanchanaburi town is the regional hub for buses and trains, with Bangkok's airports three to four hours away by road.

The dam's public viewpoints and grounds are generally accessible during daylight hours, with security controlling sensitive areas of the working facility. Boat operations follow daylight too; check locally for current access arrangements, which can tighten around infrastructure without notice.

Viewing the dam and its grounds is typically free or subject only to nominal charges, while boats, raft stays and the adjacent national park carry their own fees. Arrangements vary, so carry cash in Thai Baht and confirm on arrival.

Floating raft restaurants near the dam and along the lake serve grilled fish and Thai standards over the water, and simple eateries dot the Si Sawat road. Choices are rural, so day-trippers often pair the dam with the busier food stalls at Erawan's park entrance.

Lake fish is the star, grilled whole with salt crust or simmered in spicy tom soups, joined by som tam, sticky rice and orchard fruit from the surrounding hills. Eating fish caught metres from your raft table is the district's signature culinary experience.

Floating raft resorts on the reservoir, from simple fan rooms to comfortable lodges with kayaks and swim decks, are the defining stay, alongside lakeside resorts, national park lodging and campsites. Kanchanaburi town's full range lies about ninety minutes away for those touring by day.

The dam itself costs little to visit; budgets go to transport and, optionally, raft accommodation and boat charters. Groups sharing a car and raft house find the lake surprisingly affordable, while food and park fees remain modest throughout the district.

Roadside stalls in Si Sawat sell orchard fruit, dried lake fish and local honey, the district's honest specialities. There is little formal souvenir trade at the dam; browsing is better in Kanchanaburi town's night market on the way home.

Wear life jackets on boats and raft platforms, supervise children near open water, and respect barriers around the working dam. Water levels and currents change with dam operations, so swim only where raft operators advise, and drive the hill roads with care in rain and after dark.

The crest road and main viewpoints are vehicle-accessible, making the dam one of the lake district's easier sights for visitors with limited mobility, though surfaces vary. Boats and raft houses involve steps, gangplanks and floating platforms that require agility or well-planned assistance.

Thai prevails throughout Si Sawat, with limited English at resorts and none assumed at village stalls; the dam's name, Khuean Srinagarind, is instantly understood by any driver. The greetings sawasdee and khop khun, offered with a smile, remain the essential toolkit.

Combine the dam with Erawan for an efficient day, but consider a raft night to experience the lake properly. Fuel and cash up in Kanchanaburi town, book weekend raft stays ahead, and keep an afternoon margin for the return drive, which winds pleasantly but slowly through the hills.

Bring sun protection, water, swimwear for raft stays, insect repellent and cash, plus a dry bag for phones on boats. Cool-season evenings on the water call for a light layer, and a power bank is prudent, as electricity on rafts can be generator-limited.

Keep the reservoir clean by refusing single-use plastics afloat, choose raft operators with responsible waste handling, and never leave litter at viewpoints. Respect fish-breeding zones and quiet coves, and remember the lake doubles as the region's water and power source, deserving of care.

Erawan National Park and its seven-tier falls lie just down the road, and Huai Mae Khamin waterfall waits across the reservoir for a longer expedition. Lakeside viewpoints, Si Sawat's orchard country and, further south, Kanchanaburi town's wartime heritage complete the region's mix.

The dam is operated by Thailand's national electricity generating authority, which maintains the public viewpoints and grounds, while the surrounding lake and forests fall under Khuean Srinagarindra National Park. Kanchanaburi's Tourism Authority of Thailand office advises on raft resorts and lake logistics.
