Sreemangal tea gardens

The 'tea capital' of Bangladesh, a hilly region of green tea estates in Sylhet Division. Walk through the gardens, try seven-layer tea, and visit Lawachara National Park, a rainforest with hoolock gibbons.

Sylhet also has Ratargul, a swamp forest explored by boat in the monsoon. Sreemangal is about 4 hours by train from Dhaka.
