Welcome to the website of the Granta Rats, a.k.a. the Cambridge University Punting Society!

We exist to promote non-competitive boating among members of Cambridge University. To this end, we run a great value self-hire punt booking service (see bookings), along with a few social events throughout the year.

Fancy joining but don't know how to punt?! Have no fear! We offer free punting “lessons” to new members in the Michaelmas Term.

To join us in our general river-themed merriment, simply email us to ask about payment methods (cheque or direct bank transfer), or come to one of our events with 15 in cash. This entitles you to free punting for the rest of the academic year. Bargain!

For further information, explore the site, visit our Facebook group, or email us at, grantarats@cusu.cam.ac.uk and ask to be added to our “interested” mailing list.
