Micah Hanson is an expert on independent trekking in the Himalayas (indietrekking.com).
In collaboration with a Sherpa friend from Nepal, Micah launched Sherpana.com.
There hikers who don’t want to go it alone can book trekking guides online and review the guides.
In addition the site allows people to join each others treks, if they choose, so that they can share the cost of the trip with other trekkers. (It reminds me of TrekkingPartners.com, a site I’ve used in the past.)
They’ve tried to make pricing as transparent as possible, and allow people to book only the guide and pay for the food and lodging directly to the lodge owners.
Prices do look competitive. $376 each for 2 hikers to be guided on Everest Base Camp (14 days), for example.
