Hiya,

Ommmm ma ni pe me hung chants will be showered on you while you visit the Himalayan Kingdom of "Bhutan".

It is a pleasure to help you plan this trip.

Here I am just reiterating what Aditi has already said to you before.

Visiting the place in mid Feb, we can expect moderate temperature over the day time & the mercury dropping to zero at night. So make sure you carry layered clothing.

The winter is a good time for touring in western Bhutan, bird-watching in the south's subtropical jungles, and whitewater rafting. The days are usually sunny, cool and pleasant, but it's quite cold once the sun sets and you will need to pack warm clothing. From December to February, there is often snow in the higher regions and occasional snow in Thimphu. The road from Thimphu to Bumthang and the east may be closed because of snow for several days at a time.

Paro is a gorgeous beautiful valley, surrounded with lush & green rice fields. Craggy mountain hills & undisturbed serene beauty is going to fill your heart with joy especially considering it is your honeymoon

Do take a walk down the road, checking out the colorful markets with local produce & handicrafts.

I also found other locations you could get to from Paro:

Chelela Pass is a two-hour uphill drive from Paro, wherefrom you will be able to view frozen rivers, waterfalls, alpine flowers and snow on the way to the pass. This pleasant pass offers astounding views of the surrounding mountains and valleys.
