Joe and I did this trek. Glad we did it with Third Rock Adventures. They are too good with travel management and operation. This trek is truly mesmerizing. The villages of Merak and Sakteng is amazingly beautiful, needless to say, the people are great. We successfully crossed the challenging pass of Nachungla. Visited many prominent monasteries and temples. Our more than 2 weeks in Bhutan proved to be one of the best adventures, and the credit goes to Third Rock, their quality service, and outstanding team. through this review, we want to recommend them to anyone who wants to explore Bhutan, they have many other trips to Bhutan. Take our words from here, the Merak Sakteng trek is fantastic.
