Ruins of the Chilworth Gunpowder Mills

Highlight • Historical Site

The Evelyn family set up a gunpowder works in the area after being awarded the royal monopoly and the industry dominated this area for more than 300 years. The Tillingbourne operated the water mills and the valley was full of alder trees, which were ideal for making the charcoal required as a raw material for gunpowder.

St Martha's Church

Highlight • Historical Site

St Martha’s Church is a beautiful church perched on the top of a hill. Only accessible by foot, the Grade II-listed church affords breathtaking views and a real sense of tranquility. A 12th-century church existed at this location before falling into ruin by the 18th century. The church was rebuilt in 1848 and many of the original 12th-century architectural features were retained.

The River Wey flows from two distinct sources, one in Alton and one in Haslemere. It travels generally north east through pretty, rural landscape, eventually becoming a tributary to the River Thames. This bridge lies in the south of Guildford and has lovely stone steps either side.

The North Downs Way crosses the bridge and the Wey-South Path passes by. There are footpaths going in all four directions from the span.

St. Catherine's Lock

Highlight • Viewpoint

St. Catherine's Lock is the shallowest on the Wey Navigation and occupies a particularly serene spot. The lock is over 250 years old, and is still happily in use today; if you're lucky, you might see a narrowboat pass through.

There's a significant height difference between the River Thames and the canal's end point in the south – around 85 feet (26 m) – so you'll find a lot of locks if you walk large stretches of the navigation.
