Very beautiful, natural beach. The main path to the beach is a trail but there are other paths as well. The short trail to the beach starts at a parking lot where many people camp. Unfortunately, this means that the path often smells of urine and feces🤢. I also saw cows on the beach several times, but the cows didn't do anything and it wasn't that bad. In the end, the pros outweigh the cons and I would definitely recommend this beach!🏖️

A very natural looking beach with great rocks right next to it. Fantastic, especially at sunset. You have to walk down a trail though, so you should wear sturdy shoes.
