The Rock is a surfing spot that has gained a bit of a reputation among surfers looking for a challenging wave. It's located a few minutes drive after Hafnir, just beneath the power lines. To access the beach, you'll need a 4WD as parking is on rock and lava. The surrounding environment is rugged, typical of volcanic landscapes, but that adds to its unique vibe.

When it comes to surfing, The Rock offers some serious action for skilled surfers. The wave can be likened to the Box in Western Australia, featuring a jacking take-off that leads into a square barrel. It handles swell sizes up to 6 feet (about 1.8 meters) and works best with overhead swells. The optimal swell direction is from the west, but it can accommodate swells coming in from the southwest and northwest as well. You'll find both left and right wave directions here, making it a versatile spot if you're up for the challenge. Just be aware that as the tide increases, the break can get a bit tricky, occasionally sucking dry. This spot is really suited for experts only, as it demands a good level of skill and experience.

For the best conditions, aim for autumn or winter when the swell is more consistent. The preferable wind direction is from the east, and it works best at low tide. It's not the most reliable spot, so make sure to check the swell period; a 9 to 10-second period tends to bring better waves. Overall, it's a spot where only experienced surfers should take on the challenge due to its powerful waves and changing conditions.
