Located in the Point Reyes Headlands, Chimney Rock is a rocky blufftop area with multiple unnamed sandy beaches below it. Chimney Rock is a part of a national park known as Point Reyes National Seashore. The beaches below Chimney Rock have light brown sand. However, it is important to note that these beaches are inaccessible to the public as many of them are located below extremely steep and unstable bluffs with no access route. In addition, accessing the beaches below Chimney Rock is also prohibited by the National Park Service as it endangers the pristine biodiversity of the national park.
