Tewin is set in a superb rural landscape which retains many features characteristic of ancient countryside and which supports a rich variety of wildlife. The village contains areas set aside for the Hertfordshire and Middlesex Wildlife Trust which are carefully managed by volunteers.
The Mimram
Tewin grew up around the river Mimram, which still flows through Tewin. This is fed by many springs in Tewin, and is a rare chalk stream. This river, and the wildlife it supports is vulnerable - see the Friends of the River Mimram Facebook page and The Mimram on Walsworthblog for more information.
Panshanger Park
Tewin borders Panshanger Park, which is gradually being opened to the public. You can now walk the Oak Trail, and see the Broadwater, the Great Oak, the Orangery and the location of Panshanger House, with its views across the Repton historic landscape. The park is owned by Tarmac, who have finished extracting the gravel, do visit their Panshanger Park website to find out more about the park. See also The Friends of Panshanger Park Facebook page. Friends of Panshanger Park have long campaigned for the full re-opening of the park.
