Look, you can tell it's dead posh by its oak-framed information board.
The moment you leave gracious suburbia, you're in Bishops Knoll, once part of a mediaeval deer park and later, in the 19th century, the gardens of a (now demolished) mansion, complete with terraces, an arboretum, orchards, lawns and paddocks. We stuck to the footpath through woodlands to get down to Bennett's Patch and White's Paddock, alongside the River Avon, being inspected all the way down by a persistent Southern Hawker.
Being next to the river means it's also alongside the Portway, one of the busiest and fastest roads in the city, and the Severn Beach line - between the two, in fact, and very noisy. But I have a handy trick for dealing with that, which is to pretend the traffic is the ice-age torrent that originally carved the Gorge. That way it doesn't impinge after a while.
Our reason for coming here was to see the whales in their new home. Well - not real ones, obviously; rather, the wicker ones designed by Cod Steaks, which graced Bristol during the city's stint as European Green Capital (back in the halycon days before our ex-Prime Minister asked a stupid question and got a very stupid answer).
Here they are in their sea of plastic bottles in Millennium Square, exactly a year ago.
And now they are surfacing in the city's newest nature reserve.
They remind me quite a lot of the beached barges at Purton near Sharpness, which we went to see just over three years ago.
Instead of going back over the railway bridge, we walked down to the tunnel that goes under the track.
Being a geek, I was excited to spot a brick from the old Cattybrook Brickworks near Almondsbury - one of those names I hope to fit into a poem one day.
