Penthièvre is a surf spot located between Kerhillio and the isthmus of Penthièvre. It features a long stretch of beachbreaks that are sheltered, making it an inviting place for surfers looking to catch some waves. While it's not known for handling big swells, it can offer some decent surf when conditions align, especially at high tide. The vibe here is pretty relaxed, suitable for a range of surfers, from beginners to those looking for a more laid-back session.

The waves at Penthièvre can work well with swells coming from the Southwest or West, particularly when the size is around 1ft (0.3m). You can expect to find both left and right beach breaks here, with waves breaking over an uneven reef and sand. The beach works best with a northeast wind and it’s ideal during high tide. While the waves can be a bit inconsistent, you might score some nice walls mixed in with close-outs. It's definitely a spot that beginner surfers will find enjoyable, especially at nearby areas like Les Crevettes or Palissades for something smaller.

There are good vibes across the entire area, including the popular Tata Beach for those looking to chill out after a session. The nearby environment has a municipal camping site and facilities scattered around, making it convenient for those staying in the area. Overall, Penthièvre is a practical choice for a surf day without too much hassle.
