Entry points – there are 2 wooden poles and temporary ‘steps’ dug into the earth/clay bank. Best entry and exit point, east of lock. Or by model boating club platform if not there (beware chicken wire), or muddy bank west of large pool. Pool and most of canal weed free, possible to swim upstream for just under one mile. Car parking spaces (sometimes in use for restoration works), also just along lane.
