One of Vancouver Island's most scenic estuaries

The Courtenay River Estuary is one of the most ecologically rich and scenic estuaries on Vancouver Island. The paddling here is easy to access and offers calm waters, making it ideal for kayaks, canoes, and stand-up paddleboards. Launch points are close to town, yet within minutes you feel immersed in a quiet, natural world. Whether you’re gliding through mirror-like water at sunrise or watching the tide shift through the salt marshes, the estuary offers a paddling experience that is both relaxing and deeply connected to nature. And the scenery is breathtaking: lush tidal marshes, mountain backdrops, and wide-open skies create a serene environment. Bald eagles, herons, seals, and a variety of migratory birds are commonly seen, offering exceptional wildlife viewing, especially during spring and fall migrations. The estuary is especially unique for its blend of freshwater and saltwater ecosystems which support an incredible diversity of life. Rich eelgrass beds and mudflats are vital nurseries for salmon and other marine species.

The area also holds cultural and historical importance for the K’ómoks First Nation. The estuary was, and remains, a vital source of food, transportation, and spiritual connection. Its rich ecosystems supported traditional harvesting of salmon, shellfish, seaweed, and other marine life, and numerous archaeological sites in the region speak to a long-standing relationship between people and place.
With European settlement in the 19th century, the estuary saw dramatic change. Logging, agriculture, and urban development altered its natural flow and degraded habitat. Yet, even as the land was reshaped, the estuary remained central to the region’s economy and identity. The Courtenay River became a key transportation route, and the surrounding marshlands supported farming and industry.
In recent decades, growing awareness of the estuary’s ecological value has spurred conservation efforts. Today, it is recognized as one of the most important estuaries on Vancouver Island for biodiversity. It supports migratory birds, endangered species, and acts as a critical nursery for salmon.

As both a historical and ecological treasure, the Courtenay River Estuary serves as a powerful reminder of the connections between land, water, and people—past, present, and future.

Hazards:

  • Mudflats that dry out at low tides
    Large mudflats are exposed when tidal heights drop below 2.4 m. These flats can leave paddlers stranded on either side. Channels shrink, water becomes shallow or disappears, and navigation becomes difficult or impossible until the tide returns.

  • Strong tidal currents and flow reversal
    As freshwater from the rivers meets the tidal inflow from the sea, currents can shift direction, strengthen or weaken rapidly. Particularly near the mouth of the estuary and in the main river channel, currents can make paddling upstream hard, and downstream fast when the tide is going out.

  • Obstructions / logs (strainers), snags and entangled gear
    There are logs, tree debris and other obstructions in the water — submerged or floating — especially near the channel margins.

  • Shallow water & grounding risk
    Outside main channels, water can be quite shallow even at moderate tides. Large finned boards or kayaks can hit bottom, scrape, or get stuck, damaging craft or delaying progress.

  • Changing weather, wind & chop
    Open estuarine areas (especially nearer the harbour or Comox Bay) are exposed to wind; even small winds can generate uncomfortable chop. Weather changes can worsen conditions quickly.

  • Limited visibility & navigational confusion
    Low tide exposes large expanses of flat mud or marsh; channels become narrow and can shift or be obscured. It can be hard to judge where the navigable water is (especially in cloudy/light‑drag condition or late in the day). Mistakes may lead to running aground.

  • Environmental sensitivity / habitat conflicts
    Some parts are important for wildlife: eelgrass beds, bird nesting/feeding areas, sensitive saltmarsh. Paddlers straying off designated channels may damage habitat or violate local restrictions. Marked sensitive areas (fenced or cordoned marsh grass) exist.

    Courtenay Marina Park

    Public concrete / paved ramp used often by kayaks, canoes, paddleboards. It is a primary launch for paddling the Courtenay River estuary. Free parking for about 20–30 vehicles nearby.

    Estuarine Mixing / Tidal Influence

    Fresh water from the Puntledge & Tsolum Rivers meets tidal salt water from Comox Harbour / Strait of Georgia. At high tides, side‑channels of the estuary are flooded; at low tides large mudflats and eelgrass beds are exposed. This tidal rhythm governs what parts of the waterways are navigable and is one of the chief defining features.

  • 3

    Side Channels & Mudflats / Eelgrass Beds

    The estuary includes numerous side channels around the main river mouth, which are especially navigable at high tide. Underwater meadows of eelgrass are present, serving as nurseries for juvenile fish and habitat for many intertidal organisms.

  • 4

    Short Main Channel (Courtenay River Proper)

    The Courtenay River formed by the confluence of the Puntledge and Tsolum flows is very short (~1 km) before it enters Comox Harbour. This reaches from the river‑junction downstream to its mouth; this stretch experiences moderate currents influenced by both river discharge and tides.
