I spent 3 days in Viña del Mar and didn’t expect it to be such an active traveler’s dream. Follow this itinerary to walk the coastal landmarks (Castillo Wulff, Flower Clock), run the beachfront boardwalk, and explore museums. Then, wrap up with a day climbing the Concón Dunes, relaxing on Reñaca Beach, and following the long, scenic cliffside path back toward Viña.
