The Giant Sand Dune on PCH Across From Thornhill Broome Beach in Point Mugu
One of the many unique things to see in Ventura County is the gigantic sand dune located on the east end of Thornhill Broome Beach in Point Mugu.
Driving north up PCH, you'll see the sand dune on the east side after passing by Sycamore Canyon/Sycamore Cove Beach and before reaching the entrance to the Thornhill Broome Campground.
Park on the shoulder off of PCH. There's plenty of room, though you may be partially parked in the sand. You can also park on the beach side of PCH but rather than taking your life in your hands jaywalking across PCH, you're better off parking on the mountain side of the highway.
The mysteriously large sand dune is the result of "Aeolian transport," or the wind's movement of particles, in this case, sand. Quite steep this hill is, but your effort will be rewarded with some beautiful views of the Pacific Ocean. Plus, you get a nice bird's eye view of Mugu Rock.
We noticed that the southern-most portion of the sand dune seems to have more large rocks in the sand from erosion of the mountains above. The northern hill, at least the several times we've now been there since originally posting this, has somewhat less rocks, leaving the sand smoother and more comfortable to walk on.
Going down the hill is certainly a lot easier than coming up!
