Make your way to Fisherman's Wharf to board your double-decker bus. Climb aboard as twilight falls, choosing whether you'd like to sit on the bottom level or the top level, which will be either open-top or glassed-in. Make yourself comfortable as the bus departs and your guide begins their live commentary.
Wind through the city streets of San Francisco, admiring views from the summits of many of its famous hills. Pass the gates of historic Chinatown, cruise through the Marina district and stop at a scenic overlook for photo-worthy views of the Golden Gate Bridge.
Cross the Bay Bridge to Treasure Island, an island in the middle of the San Francisco Bay, where you can look back at lit-up views of the city skyline as darkness falls. You'll also have an unobstructed view of the Bay Lights, installed to celebrate the Bay Bridge's 75th anniversary and now a permanent feature. The 25,000 LED lights twinkle and dance to present patterns and pictures along all 1.8 miles (2.9 km) of the bridge each night.
Your 2-hour tour ends back at Fisherman's Wharf.
