Kouchibouguac National Park

Kouchibouguac National Park — the name derives from the Mi’kmaq word meaning “river of long tides” — protects 238 square kilometres of lowland coastal wilderness on the eastern shore of New Brunswick facing the Northumberland Strait. The park is a landscape of extraordinary gentle beauty: barrier islands and sand dunes sheltering warm, shallow coastal lagoons; river estuaries (the Kouchibouguac, Black, and St. Louis rivers) cutting through lowland Acadian forest to the coast; raised peat bogs of remarkable ecological richness; and the warm, shallow Northumberland Strait waters that make this the warmest ocean swimming destination in New Brunswick.

The park’s offshore barrier islands (Kelly’s Beach and the Kellys Beach lagoon system) create a protected coastal environment where the Northumberland Strait waters warm to 20-24°C in July and August — the warmest seawater in Atlantic Canada outside of Prince Edward Island. The park is also one of the most important piping plover nesting sites in Canada (the endangered shorebird nests on the sand dunes and barrier beach ridges) and a staging area for tens of thousands of migrating waterfowl in fall. Kouchibouguac is a park of quiet, light-filled coastal beauty — less dramatic than Fundy but supremely accessible and ecologically rich.

Kouchibouguac’s primary recreation draw is the barrier beach and lagoon system at Kelly’s Beach — the boardwalk crosses the coastal lagoon to the offshore sand bar where the Northumberland Strait ocean water (20-24°C in July and August — the warmest seawater in New Brunswick) provides the finest ocean swimming in the province. The lagoon itself (shallow, sheltered, and warm — warmer than the open Strait) is perfect for beginning sea kayakers and canoeists, and for families with young children. Sea kayaking and canoeing are the park’s signature paddling experiences: the lagoon system, the river estuaries (the Kouchibouguac and Black rivers are calm, meandering river-estuary paddling routes through coastal forest and salt marsh), and the inter-dune ponds are all accessible by paddle. Canoe and kayak rentals are available at the park. Cycling is exceptional at Kouchibouguac — the park has 60 kilometres of multi-use trails suitable for cycling, including a dedicated bike path system that connects all the major day-use areas and campgrounds; the flat, forested terrain makes the park one of the finest cycling destinations in Atlantic Canada. Hiking trails include the Osprey Trail (a 2-kilometre loop through old-growth black spruce bog that provides excellent bird-watching, including osprey, northern harrier, and the bog-specialist songbirds), the Kouchibouguac Estuary Trail (exploring the coastal salt marsh and estuary habitat), and the Bog Trail (a boardwalk loop into a raised sphagnum peat bog). Fishing in the park rivers (trout fishing in the black-water streams is a traditional activity; fishing licences required).

Summer (late June through August) is Kouchibouguac’s primary season — the Northumberland Strait waters reach their maximum warmth in late July and August (20-24°C; the warmest ocean swimming in New Brunswick), the lagoon is calm and warm for kayaking and family swimming, and the park’s full complement of facilities and programming is open. The piping plover nesting season (May through July) keeps portions of the Kelly’s Beach area and the offshore dunes closed — check with Parks Canada for current plover-closure areas before planning beach access in May and June. The fall bird migration (August through October) transforms the coastal lagoon and estuary into a staging area for tens of thousands of ducks, geese, and shorebirds — the park is one of the finest fall waterfowl viewing sites in New Brunswick, with American black duck, common eider, scoter, and greater scaup in impressive numbers. Fall cycling and hiking (September through mid-October) are excellent — the crowds thin sharply after Labour Day, the fall colour in the coastal forest (red maple, black spruce, yellow birch) is beautiful, and the cycling conditions are ideal. Spring (May through June) is quietest, with the shorebird migration (particularly piping plover and various sandpiper species) beginning as the coastal areas open up after winter.

Kouchibouguac National Park’s landscape is young by geological standards — the barrier islands, sand dunes, coastal lagoons, and river estuaries are primarily the product of post-glacial sea-level change and the ongoing sediment dynamics of the Northumberland Strait. The barrier sand bars and dunes (including the Kelly’s Beach system) are formed from sand transported southward along the coast by longshore drift from the eroding glacial till bluffs to the north; the barrier islands are dynamic — they migrate and shift with storms, and the park manages their protection as active coastal landforms. The raised sphagnum peat bogs (one of the best examples in New Brunswick — the Kouchibouguac bog has been accumulating peat since shortly after deglaciation approximately 10,000 years ago and is now over 3 metres deep in places) reflect the post-glacial development of the coastal lowland environment. The red sandstone bedrock of the Northumberland Strait region (similar to that of Prince Edward Island across the strait) is visible in the erosional scarps and beach cobble but rarely as prominent cliff faces — the coastal landscape is dominated by soft sediment rather than hard rock. The ongoing erosion of the coastal bluffs to the north (accelerated by storm-surge erosion) supplies the sand that maintains the park’s barrier beach system.

Kouchibouguac is one of the most important wildlife habitats in the Maritime provinces for a suite of species associated with coastal wetlands, barrier beaches, and peat bogs. The piping plover — one of Canada’s most endangered birds, with fewer than 100 pairs nesting in New Brunswick — nests on the park’s sand dune ridges and barrier beach flats; the park is one of the most carefully managed piping plover nesting sites in Atlantic Canada, with nest exclosures, predator management, and seasonal beach closures in plover-nesting areas. Grey seal and harbour seal haul out on the outer barrier islands and are commonly seen from the Kelly’s Beach boardwalk and from kayaks in the lagoon. Common tern and least tern nest on the barrier islands in summer. Osprey (abundant throughout the park — the river estuaries and coastal lagoon provide excellent fishing for nesting osprey; the Osprey Trail observes active nests), bald eagle, and northern harrier hunt the coastal marshes. The coastal lagoon and estuary system hosts exceptional fall waterfowl concentrations: American black duck, mallard, common eider, common goldeneye, and diving ducks in impressive numbers. Atlantic salmon and brook trout inhabit the park rivers. The peat bog supports a characteristic boreal songbird community (Lincoln’s sparrow, palm warbler, and yellow-rumped warbler are common in the bog in summer).

Kouchibouguac National Park encompasses a gradient of coastal ecosystems compressed into a narrow coastal zone: open-water Northumberland Strait, offshore sand bars, coastal dunes (with dune-specialist vegetation including marram grass, sea rocket, and seaside goldenrod), protected lagoon, salt marsh, coastal forest (white spruce, red maple, white birch), and raised sphagnum peat bog. This gradient produces a corresponding diversity of wildlife habitats in a small area. The coastal lagoon ecosystem (sheltered from the open Strait by the barrier island, warmed by shallow-water solar heating, and fed by the tidal exchange through the lagoon inlets) is one of the most productive marine nursery habitats on the eastern New Brunswick coast — the lagoon supports a dense community of juvenile fish, invertebrates, and the shorebirds that feed on them. The peat bog is a living ecological archive of the post-glacial coastal environment — the sphagnum moss and the bog plant community (pitcher plant, sundew, Labrador tea) are characteristic of the boreal peatland ecosystem. The park’s coastal barrier system is actively managed to maintain the dune ridges that protect the lagoon; storm overwash events and long-term sea-level rise are ongoing challenges for barrier conservation.
