Neyland to Johnston: Brunel and Westfield Railway Trail

Start at the free public Brunel Quay car park in Neyland, beside the waterfront and Brunel memorial. Walk north along the traffic-calmed marina road, following the signed Brunel and Westfield Trail past the yacht basins. At the head of the marina the road becomes a surfaced shared path. Stay on the low-level trail beneath the high Westfield Pill bridge; do not follow Route 4 up onto the bridge.

Continue through the wooded edge of Westfield Pill, then along the former railway past Rosemarket towards Johnston. The old railway alignment gives the walk gentle gradients and long, straightforward stretches between trees and farmland. There are minor road crossings along the railway trail, with gates at some crossings. Stop and check traffic at each one. At the Greenhall Park junction in Johnston, where the access lane joins the shared trail, turn round and retrace the same route to Brunel Quay.

Allow about 3 hours 45 minutes for the nearly 14 km return, including short pauses. Most of the route is tarmac, but wet leaves can be slippery and the shallow uphill return sections add effort over this distance. The marina stretch carries vehicles, so stay alert there and give space to cyclists on the shared trail. Keep dogs on leads through the nature reserve and leave the lagoon banks undisturbed. This walk stays on the established trail and uses no shoreline or tidal crossing.

Neyland has shops and places to eat, with refreshments around the marina; check opening times before relying on them. Check parking signs and any temporary trail notices on arrival.
