The Walled Gardens of Cannington - Somerset
Set in a strange spot just off the A39, amidst an EDF energy training centre is The Walled Gardens of Cannington. We'd seen snippets of the inside on a few people's Instagram feeds and deemed it worth a physical investigation - especially as it was on our route to get home from Cornwall.
We paid a very reasonable £3.95 entrance each (it's £1 cheaper in low season) and were not disappointed. The glasshouses are extensive and provide a number of different climates for exploration including arid, sub-tropical and tropical areas.
