Amwell Nature Reserve is a former gravel pit in the Lee Valley near Ware. It supports internationally important numbers of wintering wildfowl, along with outstanding communities of breeding birds and of dragonflies and damselflies. All nineteen species of dragonfly and damselfly resident in Hertfordshire have been recorded, making this the county's best site for dragonflies. These include hairy dragonfly, red-eyed damselfly and southern hawker. The dragonfly trail is open from May to September and gives you the chance to view dragonflies close up, hunting over open water.
