A true hidden gem. Stepping onto Wilderness Island feels like entering another world — vibrant colours, birdsong even in winter and the sound of water from the river. Ponds, bridges, fallen trees, flowers and little dens create a quiet adventure. Looks small at the entrance , it feels larger inside with winding pathways inviting you to wander for a couple of hours.

There is an entrance from where Strawberry Lane, River Gardens and Mill Lane meet. It's a metal kissing gate, and not for the portly! There's a circular path around the edges and two wooden bridges across to the island. Some paths have tree roots across them. Birds heard on my afternoon visit were magpie and chiffchaff, plus a robin. Mostly peaceful but train noise from nearby railway line.

Connecting with nature in Autumn at this island is such a treasure. A peaceful and quiet place to relax. Be prepared to wear boots in case of rain/mud. Unlike a park this place truly deserve its name being both an island (surrounded by water) and totally wild.

Suburban nature reserve managed by the redoubtable London Wildlife Trust and encircled mostly by the River Wandle and the railway track. The only entrance on River Gardens with a variety of pathways meandering through the confined terrain over bridges, through woodland, ponds - varied flora and fauna habitats A “contained” environment evidencing meticulous maintenance. Exemplary, quiet and well-worth seeking out. Delightful. ( why are dog’s allowed here ? )

Surprising large area with winding pathways through trees and small water areas. It is hilly and uneven in aces, but that is how the site naturally is. It is looked after by the London Wildlife Trust. There wasn't much wildlife visible but lots of birdsong.
