Recently did a 10 days cultural and photographic trip to western and central Bhutan. Booked though Druk Lhaksam Tours and Trek, a local travel agency based at Thimphu. The driver and the guide provided by them were very friendly and knowledgable persons. The rate is also very reasonable. I went to the villages and thanks to my guide who helped me communicate with the local people there. I was welcomed at all the houses we approached and I had wonderful experience there.
I highly recommend "Druk Lhaksam Tours and Trek" for their professionalism in managing tour logistics and friendly attitude. I would always book through them for all my future trips to Bhutan.
