Hiking map of the Everest

This map covers the best known trekking area of Nepal: The Everest basecamp and the Gokyo-Trek starting from Namche Bazar. There is a free version available which includes only the basic information (no POIs, no contour lines) and a extended version which includes all the remaining data but costs 15€.
The same supplier now also offers a Nepal basemap as well as a streetmap of Kathmandu but unfortunately also just in a very simple version for free, all three maps together in the full version can be bought for 48€.
