Erawan National Park
Best known for its stunning seven-tiered waterfall, this 550 km² park is easily accessed by public bus from Kanchanaburi.
The cascading and pooling waterfall feeds into Mae Nam Khwae Yai, and it’s a 2 km hike to the top pool.
The uppermost fall is said to resemble Erawan, the three-headed elephant of Hindu mythology.
The trail can be steep, slippery and non-existent from place to place, so wear good walking shoes or sneakers. Also bring a bathing suit as several of the pools are great for swimming.
On weekends and holidays, the falls are very crowded, and are a favourite destination during Songkran (Thai New Year).
The admission fee is 200B and the park is open from 8am to 4.30pm.
Buses run from Kanchanaburi all the way to the entrance of the Erawan Waterfall (40B, 1½ hours, every hour from 8am to 5.20pm). The last bus back to Kanchanaburi is at 4pm.

Looking for the dragon's lair...
In order to find the cache you will have to enter the park and check each level of the waterfall until you find the dragon's lair (a very characteristic hole in the wall of the mountain barely hidden by the waterfall).
Then, you'll have to enter inside and look for a blue box wrapped in a orange plastic bag.
Good luck to you and be carefull not to wake up the beast!
