If you want a nice hike followed by a trip to the beach; the best thing to do is hike out of the Big Sur State Park area to Barlow Flats Camp. You can park your car at the Forest Service location, $5 per day, and hike up the canyon. You might want to go as far as Ventana Camp.
When returning you can then go to the beach, two miles or so on a nearby road, check your maps. It is nice to take a lunch out there.
