2 Best Sights in Around Bangkok, Thailand

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 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.
