The 28-metre pool, filled with natural spring water heated to 27°C will open for its 152nd consecutive year on Thursday (May 19).
The usual range of sessions including fitness swims, family swims and aqua aerobics will be available.
This year there will be a mix of sessions that must be pre-booked as well as drop-in sessions where there is no need to book.
The pool is a registered charity run by a committee of volunteers for the benefit of the community.
All the up-to-date information, including how to book, what sessions are available, pool hire and special events can be found on the pool’s website: cirenopenair.org.uk
