As previously mentioned, Mendocino is a very good fly-in destination in N Cal. The town of Mendocino is very picturesque and has lots of shopping for girls and is very artsy-fartsy. The kind of place that Steven King set most of his stories in.
You will need to call the Little River Airport office to set-up a rental car.
I would recommend staying in or around Fort Bragg, a few miles to the North on hwy 1. The North Coast Brewery, arguably one of the top micro breweries on the planet is on Main st. The original brewpub is across the street from the brewery. If you have ever had the pleasure of drinking a Red Seal Ale, you'll know the brand. They're many good eateries in and around town and of course there is plentiful shopping for tourists. The Skunk Train, a very cool little short-line railroad, takes passengers from town out onto the Redwoods which is a great trip (a buddy of mine owns it, he's a W-10 Tailwind guy).
You can stay in an Inn, B&B, vacation rental house or hotel. My family has a working cattle ranch with a 2 bedroom vacation house a few mile north of town. It's an ideal place to eat, drink, read and just unwind or you can walk around one of the few remaining big coastal ranches in California and a beautiful beach too.
This is the Northern Ca. Coast so it's mostly something you look at and don't touch. The beaches are beautiful but the water is cold. It can be cold and gray or it can be blue, beautiful and warm. If you stay more than a few days, bring a good book.
Shorbird (yes I know there's an e)
