Bus 23 goes from Outer Pessac to Mérignac Fontaines d'Arlac, one of these "poles" that we have in Bordeaux where train, tram and several lines of bus coincide. We get on it at Macédo, the stop is just round the corner from our house and outside a very smart block of flats built around an inner park and just 5 minutes walk for us.
From there the bus winds through various interesting parts of Pessac, alongside the lovely Pape Clément vineyards and through the centre of town before veering off through the Mérignac vineyards to the afore-mentioned Fontaines d'Arlac. Meringue seems to have many more big blocks of flats than Pessac and more ... adventurous ... architecture.
There you switch to tram A, past the big hospital known as CHU Pellegrin or the Tripod, over the boulevards, past the huge Meriadeck shopping centre , past the cathedral and into the city centre.
It's a great route because it takes us exactly where we need to go and you get to see some nice vineyards and open spaces on the way.
