Alamere Falls is a waterfall that falls off a cliff into the Pacific Ocean just north of San Francisco. There are reportedly only two places that waterfalls fall into the Pacific Coast like this and this, from what I’ve read, is the better of the two in terms of hiking to see it.
It’s not a difficult hike. However, if you want to see the waterfall from the beach at the bottom then the very last stretch is a tough part to do. It’s neat from the top, too, but I think it’s worth going to the bottom even though it’s a little scary scaling down there.
