4 Best Sights in Greater Kanchanaburi Province, Around Bangkok

Some of Kanchanaburi Province's most spectacular scenery can be found in this park. The main attraction, Erawan Waterfall, has seven tiers; the topmost supposedly resembles the mythical three-headed elephant (Erawan) belonging to the Hindu god Indra. Getting to the top requires a steep 2-km (1-mile) hike. Comfortable footwear is essential for the 2-hour trek, and don't forget to bring water. You can swim at each level of the waterfall (levels two through five are the most popular). The first tier has a small café, and there are several others near the visitor center. There are also 8-person bungalows costing from B800 to B5,000—the ones nearest the waterfall are quieter.

Five caves are among the massive park's other highlights. One of the caves, Ta Duang, has wall paintings, and another, Ruea, has prehistoric coffins. The caves are much farther away and are accessed via a different road. About 2 km (1 mile) from the park is Erawan Village; songthaews (B600 to B800) leave from its market and travel to the park entrance and the caves. Erawan-bound Bus 8170 leaves Kanchanaburi's bus station every 50 minutes; the trip takes 90 minutes.

The Hellfire Pass Interpretive Center and Memorial Trail is a moving memorial to the Allied prisoners of war who built the River Kwai railway, tens of thousands of whom died in the process. Along with a film and exhibits, there's a 4½-km (3-mile) walk along a section of the railway, including through the notorious Hellfire Pass, one of the most grueling sections to build. The pass got its name from the fire lanterns that flickered on the mountain walls as the men worked through the night. Many people do the walk in the early morning, before the museum opens and before it gets too hot. Allow 2½ hours round-trip for the walk. Take plenty of water and snacks; there's a small shack near the museum that sells drinks, but not much food. The pass can be busy on weekends. Bus 8203 (2 hours) makes the trip to the museum. The last bus back to Kanchanaburi is at 5 pm coming the other direction from Sangkhlaburi. The drive by car takes about an hour.

The restored remains of this 13th- to 14th-century Khmer city, 45 km (28 miles) northwest of Kanchanaburi, range from mere foundations to a largely intact, well-preserved monument and building complex. There are also examples of Khmer statues and pottery and a prehistoric burial site. You can navigate the expansive grounds with the aid of taped commentary in English, Thai, or French, available at the park's entrance. Bicycle rentals cost around B30 per hour. If you don't want to make the 45-minute drive from Kanchanaburi, take the train to Tha Kilen Station (1 hour; B20); the park is a 1-km (½-mile) walk west. There are lodgings and a small café on the grounds.

The national park's main attraction is Sai Yok Yai waterfall, which flows into the Kwai Noi River. The waterfall, an easy walk from the visitor center, is single tier and not nearly as spectacular as Erawan's. More unique are the bat caves, 2 km (1 mile) past the waterfall. They are the only place you can see the thumb-size Kitti's hog-nosed bat, the world's smallest mammal. Rent flashlights at the visitor center. Other caves worth visiting include Tham Wang Badan and Lawa Cave.

This part of the park has several options for accommodations, all without electricity. The private raft houses on the Kwai Noi River are the more scenic choices. The accommodations near the waterfall have inexpensive restaurants that are more pleasant than the food stalls near the visitor center.

Driving here from Bangkok or Kanchanaburi you'll pass Sai Yok Noi waterfall, also within the park's boundaries. Despite being taller than Sai Yok Yai, Sai Yok Noi has less water, but there's enough to swim in from June to November, when the area is often packed with Thai families on weekends.
