I have such pudding hand. I love the feeling of conkers, so smooth. These sweet chestnuts are also edible, and we saw a few people forging.
We got handed a leaflet on the way in, with a guide to identifying the trees in the parkland. It was actually quite fun, but I can't remember a single one now.
I love all the colours of Autumn and they look particularly pretty reflected in the lakes and streams.
There's loads of these 'follies' and temples throughout Stowe, and I'm going to put them all together in my second post.
Quick word of warning, some of the toilets are closed at the moment, so you'll need to plan your wee. Make sure you go in the entrance/cafe as it's your only opportunity, and you really can spend hours in the park.
We got really lucky with the weather, and it really was the perfect Autumn day.
