Cambridge University Botanic Garden

The moment you walk through the gates on Bateman Street, you're stepping into 160 acres of proper botanical heaven. It's not your typical manicured display - there's real research happening here, thousands of plant species arranged by family and origin rather than just for show. You'll find glasshouses packed with tropical specimens, alpine meadows that look like they've been airlifted from the Pyrenees, and a water garden that actually takes your breath away when you round the corner.

The Scented Garden and Winter Garden are worth the detour alone, especially if you're visiting outside peak season. Spring and early summer are glorious, but autumn has its own appeal - fewer crowds, easier walking, and the colours are worth the slightly damp underfoot conditions. Allow a solid two to three hours if you're actually looking at things rather than just wandering. History buffs will appreciate the Victorian glasshouses, though anyone with a genuine plant interest - whether that's serious gardeners or just people who like spotting rare species - will get far more out of it than those expecting Instagram backdrops.

It's free entry, which is brilliant value. The garden sits only a couple of miles east of Cambridge city centre, making it an easy morning or afternoon excursion from any of the nearby caravan parks - Cherry Hinton or the Camping and Caravanning Club site are both within striking distance. Families won't feel rushed or bored; kids can burn energy on the open spaces while adults actually absorb something. The café helps too when energy levels drop.
