We visited Vasquez Rocks Natural Area Park in Santa Clarita, California, about 25 miles from downtown Los Angeles. (Wikipedia info.)
Being so close to Hollywood, it has long been a popular filming spot; you may recognize it from TV and films such as Star Trek and many more (see the Wikipedia page for a list).
