We took a customised Annapurna Base Camp trip . We were very pleased with everyting that was arranged by the agency. Starts with the guide (Dambar) and the porter who were very professional and attentive. They spotted our streangth and difficulties (non of us had a lote of experience with that level of trekking) and were able to customise the trek accordingly.
Just to give you an example: When I had some problems with descending (slipped couple of times), Dambar simply put himself behind me, without me even asking, and made sure that my safety was there.
Also, the tours in Kathmandu, Patan and Bhaktapur were great. Exctly what we were looking for: Good, knowlegable guides and good driver.
I will recommend Shikhar Adventires services to anyone and will definitly use them again when I'm back to Nepal
