If California is one grand, sweeping gesture, a long arm cradling the Pacific, then San Francisco, that seven-by-seven-mile peninsula, is a forefinger pointing upwards. Take this as a hint to look up: you'll notice San Francisco's crooked Victorian rooflines, wind-sculpted treetops and fog tumbling over the Golden Gate Bridge. Heads are perpetually in the clouds atop San Francisco's 43 hills. Cable cars provide easy access to Russian and Nob Hills, and splendid panoramas reward the slog up to Coit Tower – but the most exhilarating highs are earned on Telegraph Hill's garden-lined stairway walks and windswept hikes around Land's End.
