Sylhet Water Kingdom & Tanguar Haor Monsoon
A monsoon-exclusive journey: boat through flooded forests and river valley waterfalls, and spend a night on a houseboat in Tanguar Haor.
This route is dedicated to the northeastern water country during the monsoon season: Ratargul Swamp Forest, Bisnakandi, and Pantumai Waterfall, followed by an overnight houseboat stay in Tanguar Haor. The itinerary depends heavily on water levels; leave room for rescheduling in case of heavy rain. Houseboat facilities are basic, making it ideal for friends who can accept simple accommodations. This route does not include tea gardens; if you wish to see tea country, consider the Srimangal route.
There is a risk of flash floods from June to July; check water conditions and heavy rain forecasts before departing.
