What are some popular outdoor activities near Chepstow?

Much overlooked as an outdoor playground near Chepstow is the River Severn south of town. Despite the big trunk roads and rail lines whooshing nearby, the countryside along the Severn’s banks is surprisingly serene and seems to possess its own microclimate, schizophrenically switching between blazing sunshine and brewing storms. Wide-open views along the Welsh and Southwest English coastlines are also gorgeous.
