Erg Chebbi, a stunning sea of towering sand dunes near Merzouga, Morocco, offers an iconic Sahara Desert experience, best accessed via organized tours from major cities like Marrakech or Fes, or by reaching Merzouga independently and arranging a local tour. While venturing into the dunes alone is not advised, guided camel treks and 4x4 excursions are essential for exploring and staying overnight in desert camps, making it ideal for both solo travelers joining groups and those seeking guided experiences. The most comfortable seasons to visit are spring (March-May) and fall (October-November) to avoid extreme summer heat or very cold winter nights. A typical visit lasts one to three nights, often as part of a multi-day tour (3-4 days including travel) from major Moroccan cities, with costs ranging from approximately $50-150 USD for an overnight camp stay from Merzouga, or $150-500+ USD for multi-day tours, excluding international flights. Visitors should pack for both hot days and cold nights, bring sun protection, and be prepared for activities like camel riding, sandboarding, and unparalleled stargazing, all while respecting local Berber traditions.
