For those using a mapping-enabled Garmin GPS receiver on their explorations, Olaf Kähler has made a free vector map for use in the unit. It is compiled using SRTM data, vmap0 data and tracks of travellers in Morocco. Especially useful when touring on pistes and tracks. You can download a free copy here.

Large scale topographic maps, the best to date regarding the terrain and elevations and for planning stretches off the main roads. Made in the 1960′s/70′s, these beautiful coloured maps are hard to obtain on paper. Luckily, they are freely available in digital format, e.g. here.

The two main overview maps of Morocco are the Michelin 742 and IGN Maroc, both scaled at 1:1 000 000 (1cm = 10km). Both have their flaws also: roads not mentioned or wrong depicted (it is however not easy to keep up with the ongoing tarmac fever in Morocco). Basically, it comes down to personal choice. In my opinion, the most beautiful and usable is the Michelin, but the IGN has the advantage that it has grid lines.
