Park in Westminster Lodge car park, walk out to Holywell Hill and turn left. Walk uphill and turn left into Sumpter Yard. The Cathedral and Abbey Church of St Albans is dead ahead. Walk around the Cathedral to the left or the right and carry on to Romeland. Go left and through the Great Gateway of the Monastery. Carry on on down Abbey Mill Lane to the fork in the road. Take the left fork, past the Fighting Cocks pub, cross the bridge over the River Ver and into the park.
Head to the right, walking along the river and then go left towards the cafe. Turn right towards the wildlife centre and Verulamium museum. Go through the car park and head up the hill to start walking around the boundaries of the park. At the top of the hill look back for a magnificent view of the Cathedral. Continue around the boundaries passing by the remains of the Roman city walls, now covered with trees and undergrowth, until the Roman Wall of St Albans comes into view near the lake. Walk towards them to rejoin the path and go right towards the old Roman Gate. Just before this take a left to head back to the Westminster Lodge car park passing by the athletics track to the right.
I love this walk. I was born in St Albans & always enjoyed our visits to the Lake. I have photos of me on the ice when the lake used to freeze over, but it doesn’t do that so much these days. We usually park at the Roman Museum and start our walk from there. Thanks for posting this route.
