Does Big Sur get sea glass? You might have a sea glass hunting expedition and make some kind of art project with them, a mosaic or decorate a stepping stone or something to commemorate the trip.

The gray whales are migrating back north in February. Carry some telescopes and do some whale watching from the shore, and if it's clear at night, that would be some great star watching. Have a satellite hunt - the person who can spot the most satellites circling wins. (My 10-year-old always wins this - she's got the best long-range vision of all of us.)

It sounds like a blast. Have fun!
