Croxley Lake, Broadacres Lake and Oxhey Dell Walk

Starting from the outskirts of Croxley Green, this 22 km (about 13.7 miles) circular walk with negligible elevation gain (essentially flat throughout) offers a gentle yet immersive exploration of Hertfordshire’s lush river valleys, tranquil lakes, and ancient woodland. The trailhead is conveniently located near Croxley Green Underground Station, making it easily accessible by public transport from London via the Metropolitan line. For those arriving by car, parking is available at the station or nearby residential streets.Navigating the RouteThe route is well-marked in sections but can become confusing at woodland junctions and lakeside paths, so using HiiKER for navigation is highly recommended. The walk weaves through a patchwork of riverside meadows, lakes, and wooded dells, with the River Gade and Grand Union Canal providing natural waypoints.Croxley Lake and Broadacres LakeWithin the first 3 km (1.9 miles), the path skirts Croxley Lake, a haven for waterfowl including swans, tufted ducks, and great crested grebes. The lakes here are former gravel pits, now reclaimed by nature and managed for wildlife. Broadacres Lake, a little further along, is popular with anglers and birdwatchers—look for herons and, in spring, the flash of kingfishers along the water’s edge.Oxhey Dell and Ancient WoodlandAround the halfway mark, at approximately 11 km (6.8 miles), the trail enters Oxhey Dell, a secluded woodland with a rich carpet of bluebells in late April and May. The dell is part of a Site of Special Scientific Interest (SSSI), home to ancient oak, hornbeam, and ash trees. Listen for woodpeckers and nuthatches, and keep an eye out for muntjac deer quietly browsing in the undergrowth.Historical SignificanceThe area surrounding the walk is steeped in history. The Grand Union Canal, which the route follows for several stretches, was completed in the early 19th century and played a vital role in the industrial development of the region. Old lock-keeper’s cottages and canal bridges are visible reminders of this heritage. Near Croxley Green, the path passes close to the site of the former Croxley Paper Mill, once a major employer in the area and a key part of the local economy for over a century.Practical ConsiderationsThe terrain is mostly flat and suitable for all fitness levels, with well-maintained paths, though some sections near the lakes and through Oxhey Dell can become muddy after rain. Waterproof footwear is advisable, especially in winter and early spring. There are several benches and picnic spots along the way, particularly near the lakes and canal, but limited facilities for refreshments, so carrying water and snacks is recommended.Public toilets are available at Croxley Green Station and at a couple of canal-side pubs along the route. Dogs are welcome but should be kept on a lead near livestock and nesting birds.This walk offers a peaceful escape into nature, with abundant wildlife, scenic water views, and a gentle pace that makes it ideal for families, casual walkers, and anyone seeking a day out in the Hertfordshire countryside.
