Jubilee Pool is open every day from 25th May to 1st September 2013. Normal opening hours are from 10.30am-6pm. Jubilee Pool was first opened in May 1935. It is located between the promenade and harbour in Penzance and is the UK's largest seawater lido, providing a fabulous venue for swimming, sunbathing or simply relaxing by the poolside. A shallow children's pool set within the main pool area provides an ideal environment for youngsters to enjoy the water in safety. The pool has trained lifeguards and there is a poolside café which is open during the season with the pool as spectacular backdrop.
