These photos are from the same walk, but on the other side of the first path, and at the bottom of an embankment which is in shade.
Old Mans Beard
Woodland ferns growing in the walls of the railway embankment
Ivy, a wonderful bird food source in winter.
Passing the Taf, at low water its usually a good place to see birds, and 7 Mergansers, the most I've seen here.
