Ashton Court, a large house, deer parks, gardens in South Bristol near Long Ashton.
Clifton Suspension Bridge and Avon Gorge - Bristol Zoo nearby.
Market area around Corn Street in the city centre.
Temple Back, some interesting buildings, statues (Brunel), steel bridge, river with a few barges - but be prepared to be 'challenged' by security staff who will tell you that some occupants don't wish their premises to be photographed ... I just smile and say something along the lines of "how interesting, it's on Google" and continue to shoot.
