A great walk to the ocean. Have done it for years, but now it is too impacted. Can hardly find room to walk, much less to park.

Head to the trailhead with a lot of parking. A long gentle downgrade followed by a variety of other trails splitting off, some to the South and some to the North. If you continue West several miles, you reach a lovely small, sheltered beach, which contains fire pits and a portable toilet. I believe this is more used by locals... More

I found this trail based on tripadvisor reviews and am glad I did. I'm not super athletic and it was a good distance and not to strenuous and strenuous enough that it felt like a hike. One tip: you will come to a fork where there is a smaller footpath to the left and a bigger trail going uphill to... More
