Charvil Lakes are on the south side of the A3032 between Charvil and Twyford, Berkshire.
The nearest car park is in Polehampton Close off Twyford High Street. The lakes are reached by walking along the High Street in Twyford towards Charvil, over the river and then left down a path after industrial units. The path is best followed round to the left which will bring you to the lakes.
The lakes are former gravel workings, many of which can be found alongside the River Loddon. The lakes are popular with anglers and contain some very large carp tench and bream. The river itself rises near Basingstoke and flows in to the Thames near Wargrave. You can see all kinds of wildlife in the area, including kingfishers, waterfowl, and occaisionally otters.
The cache is a small cylindrical container with a blue lid. It contains a log book, pencil and a few swaps.
