The undiscovered Al Hoceima National Park is a hidden jewel of this region. The park extends to 485 sq km (including 190 sq km at sea). The area is dotted with Berber settlements and criss-crossed by dirt roads, making it ideal trekking and mountain-biking territory. Its isolation has helped preserve several at-risk species, from its thuya forests to an important colony of fish eagle. While a 4WD opens up your options, a 2WD will get you through the main tracks. The park offers two regions: the central Rif bordered by the N16 in the south and west, and the coast.
Drinking water directly from a tap in Morocco isn't a good idea. However, the Moroccan authorities are concerned about the pollution caused by plastic from bottled water, and many hotels have filtered water for guests which is considered safe to drink.
