ANGEL ISLAND. One of the great things about San Francisco is its treasure-filled bay. Angel Island, only a short ferry ride from San Francisco, Tiburon or Vallejo, is perfect for either a short or long excursion. Bring a picnic lunch and idle the time away amid cool breezes and great views. If you feel ambitious, Mount Livermore, the island's 781-foot anchor, provides plenty of opportunities for hiking, beginning with a five-mile perimeter trail. From April to October, enjoy the Cove Café, and rent a bike to get around more easily. Camping is available, too.

GUERNEVILLE. Put life into perspective at this spectacular find! About an hour's drive north of the city, the state park is home to an impressive collection of coast redwoods. With a life span of 2000 years and a potential height of 350 feet, the towering specimens are as amazing as they are majestic. Marvel at them while enjoying a walk along either the nature or discovery trail, or just sit and picnic under the shade of the gigantic conifers. Although camping is not permitted in the park, nearby Austin Creek State Recreation Area accommodates lovers of the outdoors.

CARMEL-BY-THE-SEA. Waves breaking against sharp cliffs. A beach of pearly white sand. A backdrop of tree-topped rolling hills. Sound too good to be true? It's not ­ it's Carmel-by-the-Sea. This picturesque community delivers both dynamic atmosphere and a place to get away and recharge. Its relaxed pace mingles with European ambience, and its many annual arts festivals draw visitors from near and far. You can also browse unique shops, enjoy one-of-a-kind dining, and capitalize on the flexibility that such a village can provide. Proximity to scenic spots like not-to-be-missed Big Sur and charming Monterey add to the little town's big punch.

MARIN COUNTY. Make your way across the Golden Gate Bridge and step into one of the area's last bastions of open space. The Marin Headlands, known for their inspiring views, showcase Mother Nature in all her bounty. They're a great place to enjoy the outdoors, whether you choose to camp at beautiful Kirby Cove or hike along more than 200 miles of scenic trails. For the best views around, make your way to the summit of 2571-foot Mount Tamalpais. Historic military bases on the preserved site also add to the appeal.

MONTEREY. Whether you're in the mood for coastal nostalgia or hope to catch a glimpse of migrating grey whales, Monterey is not to be missed. Walk down historic Canary Row and investigate the lively district's many converted warehouses, which now house a variety of shops. Or, grab a bite to eat, breathe in the sea air, and imagine what the bustling spot used to be like. The town is also home to the world-renowned Monterey Bay Aquarium, located in a former cannery, and to Old Fisherman's Wharf, where working fishermen unload their catches. If you feel like doing some fishing yourself, book a spot on one of the available excursions. For more information, contact the Monterey County Convention and Visitors Bureau (888-221-1010).
