Along the northern end of this large lake you'll find a lovely footpath running along the lake shore and through the lakeside woodland. On open days you can also visit the Discovery Wood where you can see roe deer, badgers, foxes and otters. There are nesting boxes for owls, tits and kestrels too. On the nature trail there are wildflower meadows with Green winged orchid, knapweeds, white ox-eye daisies and pink devils bit.
There's also the Blagdon Pumping Station and Visitor Centre with science and environment exhibits, a picnic area and views of the impressive dam.
If you would like to continue your walking in the area then you could head to the nearby Chew Valley Lake for more waterside trails. The Two Rivers Way walking route runs just past the lake so you could also pick this up.
