About Basse Grilhed
Basse Grilhed is a rocky Iroise drop-off south of Aber Ildut where the reef eases from a shallower edge into a deeper kelp-covered plateau. Faults and rock ledges are coated in dense growth and shelter lobsters and octopus, making this a rewarding advanced scuba dive for divers who are comfortable with depth, buoyancy, and open-water rock terrain.
