Although camel trekking is a popular tourist activity all over the world - from Oman to India to Mongolia - there is surely no better way to test your mettle than to board a 'ship of the desert' in the biggest and most unforgiving desert of them all, the Sahara. Camel trekking in Morocco is a hugely popular thing to do, giving all visitors a chance to experience life as a desert nomad for a few days. Typical camel treks in Morocco will include a guide, light meals and bottled mineral water - as well as the unique opportunity to spend your nights in a traditional Berber tent. There are many places where these adventures can be booked, but tourists are urged to head to the small village of Merzouga and to strike out from there. As you leave Merzouga behind, an impression of total wilderness and infinite desert will descend upon you - and you will be left to marvel at the awe-inspiring Erg Chebbi dunes, which stand nearly 500 feet (150m) tall, and retain a strange and beautiful hue of burnt sienna, darkening to peach, red and purple as the sun sets.
