The little things make Big Sur a heart-warming trip.
Make the best choice: Stay in Limekiln, and opt for a campsite next to the creek. The water is cold enough for you to chill your beers (or Stumptown Coffee, like I opted for) in the eddies, and offers the same lulling noise as the beach sites but with more coverage from the elements. Don't leave the pooches at home, either, and stock-up before you get there (civilization really only has over-priced peanuts and firewood). That being said, don't make the mistake of not stopping by the local vendors for at least a frozen treat; nothing beats a chilly sunset than an ice cream bar (don't ask us why, it just works). More Limekiln camping pro-tips below.
Bring a hollow-fill mummy bag.
Take a night-hike up to the falls (don't forget your headlamps).
Visit the elephant seals. It's really a spectacle.
If you're driving from the south, San Luis Obispo has a Trader Joe's. And Trader Joe's has wasabi peas. Grab your perishable items there.
Camp with those you love; after all, the people you're with make the trip.
