The road is very rough to get here. There's tons of trash and junk everywhere. Found a note that said "Please pack out all your trash and shells. Lets keep this shooting area clean." The waterfall was one of the tallest I've seen in SD County right off a road. No hiking required. It might be seasonal as it was a little more than a trickle in early October.

The name "Los Peñasquitos" translates to "little cliffs" in Spanish, a characteristic that becomes evident at this location. Here, you'll find a creek flows through a boulder-filled area, creating a tranquil scene rather than a roaring waterfall. The surroundings offer a serene and picturesque atmosphere.

Cedar Creek Falls is a beautiful cascade that drops 80 feet into a shimmering pool of water. It's best to visit the falls in the spring or fall, when there is a higher chance of water running. The falls are located in Cleveland National Forest and there is a permit required for the trail leading up to them, so be sure to plan your hike accordingly!
