A great 4.5 mile circular walk, on the flat, around Keyhaven Marshes and nature reserve.  

Parkign in the pay & display car park, the footpath starts straight away and leads of following a small tributary.  It soon turns to a well packed gravel track that circles behind the marshes and inland, passing the entrance to the local waste centre as well as a campsite before eventually popping out in Lower Pennington and The Chequers Inn, a nice 16th Century village pub and restauarant.
