The Topanga Lookout is a beloved short hike (about two miles out and back) along the ridge off Saddle Peak Road to a wide concrete platform — the remains of an old lookout — with open 360-degree views of the ocean, mountains, and canyons. Its broad deck, ever-changing graffiti artwork, and easy access make it one of the most popular sunset spots in the Santa Monica Mountains for a big view that isn't right on the coast. Go at golden hour and bring a layer for the ridge wind.
