I trekked with Bhutan Vajra Adventures – they were fabulous!! The guide was full of insightful information, had a great sense of humour, and really friendly and helpful with any questions we had. During that week – I trekked high passes, put up many prayer flags, walked around tranquil lakes, ate breakfast surrounded by mountains, ate fabulous food, had many laughs and learnt lots and lots about Bhutan culture – people, places, geography etc. I highly recommend this company.
