Boulter’s Lock is a lock and weir on the River Thames in the north-east of Maidenhead. The lock is on the western side of the north-south reach, between the A4094 from Maidenhead to Cookham road and Ray Mill Island.
The present 1912-built lock replaces those dating from the late 16th century and that of 1772 built by the Thames Navigation Commission. The name “Boulters Lock” is invariably used for the surrounding area.
Boulters Weir is some way upstream of the lock, at the northern end of Ray Mill Island. It is one of the most popular whitewater freestyle kayaking areas on the River Thames.
Boulters Lock is to be found around 1/4 mile from Maidenhead Bridge on the road to Cookham.
