A welcome addition, right by the station down the steps on the way to Leigh on Sea on foot. Popular spot. Good coffee and food selection.

Beautiful Nature Reserve to explore while hiking the coastal path. Be aware of the Adders (snakes) though. I didn't see one, but the locals I spoke to confirmed that they're there.

C2C service is generally great at getting you back West / London when you can’t ride back! The gate is general unlocked so you can wheel your bike through rather than using the electronic gates, assuming you’ve bougth your ticket!

A little island escape full of wildlife and scenic views. Perfect for a 5km run with a mix of pathways and sand trails. The eastern section is part of Leigh National Nature Reserve, where the saltmarsh is one of the best surviving in the Thames Estuary. Keep an eye out for the rare insects and butterflies and the kestrels flying overhead.

Managed by the Essex Wildlife Trust, Two Tree Island sits on the Thames Estuary. It is popular for birdwatching and 3.5km circular walk round the island is possible direct from Leigh-on-Sea. In the past it has been a sewage treatment works and a landfill site and is now a beautiful area of reclaimed saltmarsh.

Yes, Leigh National Nature Reserve is a popular spot for dog walking. The reserve's open spaces and coastal paths are great for exercising your dog. However, it is a sensitive area for wildlife, especially birds. You should keep your dog under close control at all times and follow any local signage regarding leads, particularly during bird nesting season.
The walking trails in Leigh National Nature Reserve are generally flat and easy to navigate. Most paths are either gravel or grass, making them accessible for most fitness levels. The landscape is defined by coastal salt marshes and wetlands, so expect open, expansive views across the Thames Estuary rather than steep hills.
Absolutely. The flat terrain makes it ideal for families. For a short and manageable walk, consider the Two Tree Island Nature Reserve loop from Leigh-on-Sea. It's an easy 2.2-mile (3.6 km) circuit that offers a great introduction to the area's coastal scenery without being too strenuous for little legs.
The nearest train station is Leigh-on-Sea, which has good connections. From the station, the entrance to the reserve on Two Tree Island is a manageable walk, allowing you to start your hike without needing a car.
Yes, there is parking available on Two Tree Island, which serves as the main access point to the reserve. Be aware that it can get very busy, especially on weekends and during good weather, so arriving early is recommended to secure a space.
While you can see birds year-round, the winter months are particularly special. This is when thousands of wildfowl and waders, including large flocks of dark-bellied brent geese, visit the mudflats. Autumn and winter also offer the chance to spot a short-eared owl hunting over the marshes.
Yes, most of the popular trails in the reserve are loops. A great moderate option is the Two Tree Lagoon – Hadleigh Marsh loop from Leigh-on-Sea. This 7-mile (11.4 km) route provides a comprehensive tour of the wetlands and marshes, starting and finishing conveniently from the town.
