| The path through Mymmshall Wood towards the end of the walk |
A pleasant circular walk through pine woods, oak woodland, over open fields and down footpaths through deep hedgerows. In July and August look out for the Purple Emperor butterfly along the way. There are no pubs along this route, but two close by. The route does cross fields where sheep graze. There are notices during lambing season to keep dogs on leads. The starting point is 1.8 miles SW from Brookmans Park station by road. This route offers plenty of shade during hot summer days if started before 07:30. After that, points 1 to 2 and 3 to 4 are exposed to the sun.
