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.

To join us in our general river-themed merriment, simply email us to ask about payment methods (cheque or direct bank transfer). This entitles you to free punting for the rest of the academic year. Joining costs £22, which is less than the normal cost of renting a punt once. Bargain!

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