I Recently Visited Bichna Kandi, now there is no water, there is no advantage to go!
The road is bad too. I saw the road work going on. The road is expected to be fixed before the next monsoon.
You can go to Sylhet by train/bus from Dhaka!
You can reserve CNG from Sylhet and go directly to Bichna Kandi. It will take 1500 to 2000 TK. Ratargul will also be covered.
After reaching Bichnakandi, you can now go to the spot by motorcycle. It will take 200 Tk UP-Down. Now it is better not to go by boat as there is less water.
