Travel from Timphu to Punakha. On the way you will see Dochula Pass, a beautiful range of Snow covered Himalayas. There’s a small hill with 108 small Buddha temples. If you are lucky enough you can see some Native habitats like a wild deer of Bhutan on the way.
There’s a interesting Temple of Fertility in Bhutan, where people pray to have healthy kids.
Then in Punakha there’s a huge Punakha Dzong also known as Pungtang Dewa Chhenbi Phodrang. Beautifully constructed Dzong where monks learn their life lessons.
Then You can visit the suspension bridge of Punakha, which has no standing support.
In evening you can chill out near a river side.
