Hi there.. As already other fellow travellers advised you should concentrate on any one country if you want to travel for 3-4 days only & if possible colab your journey with weekends so that you can take advantage of it to explore more😊
Hi, It is not advisable to cover two countries in 4 day trip, you can do either of the two and since Bhutan is comparitively small you can do it. I have attached with this comment few options for you, you can click on them to find more details about them. If you want to talk to someone about the packages simply fill in your details in the form and you will receive a call.
I will suggest to either extend your travel duration as 4 days is certainly not enough time. You will feel incomplete while returning back. If you are in love with Mountain views, go for Nepal. If you are interested in Buddhist culture and monastery more, go for Bhutan. Minimum 6 to 7 days will be required to cover Main tourist points of Bhutan. 2 Days for Paro, 2 days for thimphu and 2 days for Punakha, 1 day for Haa valley
