Between Martil and M'diq, the Tétouan coast bumps out into a dark volcanic headland that gives the stretch its name — Cabo Negro, the black cape. The promontory is pine-forested, with walking trails to viewpoints over the Mediterranean, a long-established 18-hole golf course, and some of the most upscale hotels and villas on the northern coast. The beaches at its base — Cabo Negro Beach on the north side and the long Martil-side bay to the south — are among the calmest on the Tétouan coast, both because of the headland's shelter and because the development pattern (villas and hotels rather than beach clubs) keeps day-tripper density low.

The walks are easy: short headland paths of thirty to sixty minutes, gentle climbs to viewpoints over Martil and M'diq, no technical terrain. Good walking shoes are enough. The Royal Golf Cabo Negro is one of the older 18-hole courses in northern Morocco; non-members are accepted with a green fee, clubs can be rented on site, and bookings ahead are wise in summer. Standard golf dress applies. The whole headland keeps a noticeably quieter atmosphere than the busy beach towns at either end.

Spring and autumn are the strongest months for walks and viewpoints; summer is when the beaches earn their keep. Mornings are clearer for photographs north toward Jebel Musa near Ceuta. From Tétouan, Cabo Negro is about a fifteen-to-twenty-minute drive, easy as a stop in a Martil–M'diq coast loop. Infrastructure on the headland is limited — most visitors plan lunch at the seafood grills in Martil or M'diq fifteen minutes either side, rather than at one of the resort restaurants, which are mostly for guests.
