Priory Park Reigate
This large park in Reigate is great for walking with miles of woodland trails, lakes and formal gardens. You can also climb the Priory Park Ridge for great views across the town and the North Downs. The park is good for flora and fauna with pretty bluebells in the spring, 207 plant species and champion trees which you can see on the tree trail. Look out for a variety of birdlife around the large lake.
The Reigate and Banstead Millennium Trail passes the park so you can follow this trail to extend your walk.
The Greensand Way long distance walk also runs through the park so you can pick this up to continue your walk. Reigate Castle is just a short stroll away so this is another good option.
