Nature- a mind changing elements send by Gods. If you feel lonely just go with the nature. And if you want to learn about nature, tree the botanical is one of the best place to learn.
The shady, tranquil botanical gardens, stretch over 40 hectares and contain over 1000 species of local and foreign plants, as well as lots of birdlife that flock to its several lakes and ponds (particularly in winter). Some way from the centre of Dhaka, it’s a nice respite from the city’s mass of humanity. In the distance you’ll see the Turag River.
if you are lucky enough you can see birds, flowers and obviously the t=various trees. if you are a nature lover you are strongly welcome to visit.
