London Wetland Centre
(Side note: last time we visited the littlest was still pram-bound only, and I found that a more peaceful experience than our most recent visit when he was off toddling away and I had to keep a close eye to ensure he wasn’t about to leap off into a huge body of water. So if your child is toddling age, perhaps wait six months or so until they really understand why it’s best not to run headfirst at a lake…)
Of course, there’s lots of wildlife to see, of the ducks, birds and otters variety, but I am always especially taken by the glorious plants. It’s naturalistic planting at its best, in my opinion, everything appearing to be growing just where it wants to but – I am sure – in fact carefully planned and designed.
