Possil Marsh has a shallow freshwater loch surrounded by marsh, swamp and fen, with areas of willow scrub and grassland. The fen and swamp areas support locally rare plants and the reserve is also an important staging post during the spring and autumn migration for warblers and waterfowl.
There is a path, accessed from the Forth & Clyde towpath, around the perimeter of the reserve.
The reserve lies adjacent to High Possil and Lambhill, bounded by the Forth and Clyde Canal. Take the A879 (Balmore Road) north from Glasgow. The entrance to the reserve is on the right, immediately after crossing the canal and just in front of the old Lambhill Stables building. There is unrestricted parking nearby.
Starting at the reserve sign, just off the main road, follow the canal tow path and then waymarkers onto the reserve.
Please keep dogs under close control during the bird breeding season between April and August.
