Rainham Marshes - "Part of the Thames Estuary, not far from the bustling streets of London, Rainham Marshes is a haven for all kinds of wildlife - birds, water voles, dragonflies and more" "The visitor centre is accessed via a ramp from the car park (ramp entrance is next to the four blue badge bays). Visitor Centre doors are heavy, but have power assisted opening. The visitor centre and cafe are on first floor, accessed by a long ramp next to the Blue Badge parking. Entry by two sets of double heavy doors with power assisted opening, opening outwards. No threshold. Step-free, level access throughout. A mix of flat gravel surface paths and boardwalks. Trails start at the visitor centre across a short section of non slip grill with a short steep section.
