I attended Nina's yoga class there today (9am £10 for one hour). The bird song and watching the river stream past was magical. She does another class at 10.30am (Saturdays). She is funny but authentic. Mats, belts, blocks, bricks, blankets and heated lavender rice bags for the eyes are provided, but you can bring your own. It's nice to have warm layers and socks for the meditative beginning and end of the practice.
