Goodio!
Ely is also good for various cafe stops - there's lots of places where you can sit with your bike and a cuppa around the market square.
Ooh, if off-road fits your definition of fun, then the Aldreth Causeway may be worth looking up. It's a great time of year for doing it, before all the grass gets too high. It's the only place I've ever seen a cuckoo, and plenty of kingfishers round there too. I've done it on touring bike with 28mm tyres. Lovely route this time of year. It's a great time of year to be in that area generally - the flooding has (usually) gone down, roads are dried out after last year's harvest, blossom's out, swallows are on their way... 🙂
