Glanusk Estate Crickhowell takes part in the National Garden Scheme where you have a chance to visit gardens not normally open to the public. This happens every year in the latter part of May on a Sunday.
These gardens have magnificent displays of Rhododendrons and Azaleas plus many more. The naturally fed series of pools are normally full of tadpoles.
You are able to wander around large areas of the estate, including the woodland walk and visit the private church. There are local artisan stalls around the house and various talks and displays throughout the day. The best part for me is to visit early before the crouds arrive and wander down by the River Usk and just listern to the birds.
If you are hungry the local venison centre brings its catering truck or alternatively volunteers serve you tea and homemade cake. A very worthwhile cause to support.
