Upnor is a pretty village to come to for a stroll. There is free parking at both carparks at either end of the village and the village boasts a castle and several places for refreshments. You can enjoy views over the river and go for a meander either along the beach or in the woods, which are a designated SSSI area. The cache is situated next to the former Arethusa Venture Centre which unfortunately closed a few years ago and is still vacant. At the front of the centre is the Grade 2 listed figurehead of HMS Arethusa.
