Thank Poseidon for the Bodega Harbor Inn, with some of the North Coast's best lodging bargains. On a small bluff over the bay, the inn has four single-story clapboard buildings surrounded by well-maintained lawns and gardens. The rooms are small but impeccably neat and tastefully decorated with unpretentious antiques; double beds, private bathrooms, and cable TV are standard. (The best rooms are 12 and 14, which come with small decks and partial ocean views.) The clincher is the inn's private lawn area overlooking the water. On sunny days, there's no better way to enjoy an afternoon in Bodega Bay than parking in one of the lawn chairs and watching the fishing boats bring in their daily catch. Families should inquire about the vacation homes the inn rents for as little as $135 per night.
