Yoga on the Glass Floor

We're not sure that looking through a glass floor to see black cabs and buses scoot past beneath you will necessarily make a yoga class more relaxing, but perhaps participants in these vinyasa-flow classes can focus on the impressive view of the river instead. The energetic 50-minute sessions are suitable for all experience levels, but be prepared to be distracted by the possibility of the bridge's bascules raising up beneath you for a boat to pass through. Mats will be provided, but gripped gloves and socks will allow a better view through the floor. Booking essential.
