Take a trip along one of the most iconic drives in the world. Head south on Hwy 1 and see the ocean from atop sheer coastal cliffs lined with redwood trees. Stop by Pfeiffer Beach with its unique rock formations and purple sand (go early - it fills up fast), then keep going until you reach McWay Falls. On the drive back, grab lunch at Nepenthe for one of the best views on the California coast.
Right next to the wedding venue: rocky beaches, cypress groves, seals, otters, and lots of short trails to explore. Parking fills up within an hour or so after opening, but you can park along Hwy 1 where all the other cars are - it's a short hike to the coast.
Neither of us are really golfers, but we know some of you are big fans. Our golfing friends tell us this is an incredible course with the same designers as Pebble Beach - but costs ~$80 rather than several grand.
