Other known spots around
35 min drive south. Beach break, but always biggest around. Even when flat here, you might score some waves in Tamri.
40 min drive south. Really close to the rocks, only very experienced surfers. North wind = offshore. Lots of barrels!
Just south of Boilers. Same conditions.
1h drive. Taghazout (Killers, Mistery's, Anchor Point, Hasj Point, Banana Point, K11, ...) is only worth the drive when it's big enough. Imsouane always takes more swell than Taghazout.
50 min drive north. Another beautiful right point break in a remote fishing port. There are also great peaks on the beach down to and beyond the rivermouth.
The Cave / La Grotte
Ten miles south of Essaouira is the Cave or as it is known locally - La Grotte. It is a really good hollow right point on rocks in a rather secluded spot. If you don't have a 4x4, you're facing a 30 min walk.
75 minute drive north. Punchy beach break, rarely crowded in winter. Also check the river mouth south of the beach for good rights and lefts!
Within a 1h drive from Imsouane there are still many spots to discover which will work on different tides. Search and find the pot of gold!
