Climb to the top of San Francisco’s tallest skyscraper to get panoramic views of the city and bay from 1,070 feet high. Created by renowned architect César Pelli, this 61-story obelisk-shaped tower serves as the office for Salesforce and occasionally opens up to the public for tours and viewings on its highest floor. Slots are limited though, so book as soon as they are available to secure your spot. Even if you're not able to head up the building, you'll likely pass by the tower on a guided city tour of San Francisco. – Tripadvisor
