Bognor Marsh is a unique area. At Bognor Marsh, not only can you
search the quiet waters of the marsh for amazing aquatic creatures,
such as Water Boatmen, Giant Water Bugs, and Caddisfly larvae, but
you can also stand on the brow of the Niagara Escarpment and look
down on the backs of turkey vultures as they soar on air currents
above the marsh.
This management area is one of the largest marsh systems in Grey
County. It encompasses 668 hectares of escarpment upland forests,
three major marshes, reforested areas, natural regeneration areas,
and several small springs feeding the marsh and stream system. A
tributary of the Bighead River, joined by a feeder stream, runs
easterly through the property. The water level in the larger of the
three marshes is controlled by a Ducks Unlimited dam, in an effort
to enhance habitat for waterfowl, and other marsh-living animals,
birds and plants.
At Bognor Marsh you will find 11.9 km of trails, an education
shelter, boardwalks with interpretive signs, a viewing tower,
access to the Bruce Trail, and washroom facilities. Bognor Marsh is
a multi-use area visited by school classes, hikers, naturalists,
birders, and hunters. For this information and more, please visit
Grey-Sauble Conservation Authority: Bognor Marsh.
The posted coordinates are for the beginning of an impressive
boardwalk built out into the marsh. This cache is an offset cache
requiring you to obtain information from the plaques that are
located at equally spaced intervals as you walk the boardwalk in a
counter-clockwise direction. The answer that you provide to the
question associated with each plaque will generate a digit in the
coordinates for the cache. Once you’ve completed your walk
along the boardwalk, and enjoyed some time in the viewing tower,
you can then relax in the picnic shelter while you determine the
location of the cache, and plan your route to it. Our advice is to
commit to walking the entire loop (approx. 5-6 km) in order to
fully appreciate the sites and sounds of Bognor Marsh. As you seek
this cache, please remember to practise good environmental
stewardship, and apply the principle of Cache In, Trash Out.
*Congratulations to the lighthouse gang for being FTF (and for
getting their 200th cache)!
