St Martha's Hill and Colyer's Hanger

St Martha’s Hill and Colyer’s Hanger is a 38-hectare nature reserve in Surrey. It lies north of Chilworth and is owned by the Albury Estate. The land is managed by Surrey County Council. Colyer’s Hanger is a Site of Special Scientific Interest and a Grade 2 Nature Conservation Review site. Earth circles on the hill are likely linked to tree planting for Chilworth Manor and are a Scheduled Monument. The summit of St Martha’s Hill holds a small church with views across eight counties on clear days. The site mixes woodland with calcareous grassland. This grassland supports rare chalk-loving plants. Access points include Guildford Lane and Halfpenny Lane. Visitors walk through quiet woodland paths to reach the open hilltop. Wildflowers colour the grassland in spring and summer. The church stands as a landmark near the highest point. From here, wide views stretch across the Surrey landscape. The contrast between shaded woods and sunlit slopes adds to the reserve’s appeal.
