Make the most of your time in London by combining a hop-on hop-off bus tour with an admission ticket to the Tower of London. Spend 24 hours using the bus pass, giving you the flexibility to visit landmark destinations that fit your interests. Then, visit the UNESCO World Heritage-listed Tower of London at your convenience, and enjoy the treasures on display, including the Crown Jewels. To top it all off, take a one-way Thames River cruise between the Tower of London and Westminster Pier.
