Archway Road and Muswell Hill Road. Cranley Gardens to Alexandra Palace The route between the northern end of the Highgate Tunnels to the Northern line depot at Wellington Junction is used by trains entering the depot; the rest of the cutting around Highgate Wood from Wellington Junction to Cranley Gardens is outside the wood's fence. It is not officially part of Parkland Walk and so is allowed to stay overgrown. A further shorter section of the walk begins along Muswell Hill Road, just beyond Cranley Gardens, where the road overbridge crosses the old line. The site of the former Cranley Gardens station and the old trackbed has been replaced with a school and housing. The walk continues opposite via steps down to the trackbed towards Alexandra Palace, which skirts a hill. The span of the seventeen-arch viaduct over St James's Lane gives a view eastwards and southwards over London. The route ends with a reconstructed overbridge under Muswell Hill itself. At this point, Muswell Hill primary school has been built on the trackbed. The pedestrian route by-passes the primary school and leads into Alexandra Palace Park proper. Further remains of the rail route can be seen in Alexandra Park. The Alexandra Palace station building still exists and is used for community purposes. Wildlife Flora No trees were permitted to grow close to the track when the railway was operational. The range of trees found today has grown up in the last fifty years. Most arrived naturally (oak, ash, birch, hawthorn, cherry, apple, holly, rowan, sycamore and yew), but a few additional species have been planted (field maple, hazel, black Italian poplar and white poplar). More than three hundred species of wild flowers have been recorded on the Parkland Walk. They range from commonplace to exotic. Species sighted include Michaelmas daisies, goldenrods, buddleia and Guernsey fleabane. Fauna The great variety of plant life sustains a wide range of animals. Twenty two species of butterfly have been recorded. Hedgehogs benefit from the proximity of adjacent homes and occasional feedings from homeowners. Foxes are plentiful and muntjac (a small species of deer) are seen occasionally. A colony of slowworms thrive along the grassy embankment. More than sixty species of bird have been seen along the walk and many breed here. Parkland Walk is known to be an important site for bats in the London context, providing important foraging habitat and an excellent dark
