The Golden Triangle is where the borders of Thailand, Laos, and Myanmar meet on the Mekong River. Once the center of world opium production, today it's a tourist attraction with panoramic views of three countries.

On the Thai side stands a huge golden Buddha statue and the Hall of Opium museum telling the history of drug trade in the region. From the shore, you can take a boat trip along the Mekong with a stop at the Laotian market.

Nearby is the luxurious Anantara resort with views of three countries and an elephant camp. Best time to visit is morning when fog over the river creates a mystical atmosphere.
