With the rolling sands of Baker Beach just steps away and many park trails nearby, this neighborhood is the ideal base camp for nature lovers, active households, and those who just like to drift off to the sound of ocean waves.   Dotting the hillside above Lincoln Boulevard since the 1950s, the Baker Beach apartments have surprises inside, such as hardwood floors and updated kitchens. Large windows in each of the two-, three- and four-bedroom configurations provide generous natural light and in some cases Pacific Ocean views that rival those of neighboring Sea Cliff. Though the standard foghorn soundtrack might say otherwise, sunsets here are more often fiery oranges and reds than shades of gray. Outside, native plants and grasses share space with organic community gardens, neighborhood gathering spaces, bike racks, and playgrounds. Nearby stops for the PresidiGo Shuttle make for easy access to the Presidio's Main Post and the free shuttle to downtown San Francisco.
