Westport Bay is the inner, southeastern portion of the larger Clew Bay on the Atlantic coast of County Mayo. It is a tidal estuary characterized by a narrow, five-mile-long approach channel leading to Westport Quay. The inner bay is calm and sheltered, making it suitable for paddlers of all levels, particularly when launching from Westport Quay to explore the protected waters with outstanding views of Croagh Patrick. The bay features a maze of small islands, offering numerous anchorages and sheltered spots among the islets. For more exposed coastal kayaking, experienced paddlers can consider trips to Clare Island, which features sea caves and cliffs, though crossing from the mainland requires calm conditions and careful planning. Key launch points include Westport Quay and Pigeon Point. The Mayo Sailing Club at Rosmoney, on the shores of Westport Bay, offers a pontoon, slipway, and other facilities about ten minutes from Westport town. Navigation requires attention as the approach channel is narrow and intricate, with shellfish beds in the bay where anchoring should be avoided. The area is exposed to Atlantic weather systems which can develop quickly, so checking the marine forecast is essential. Tidal currents on this coast can be strong, particularly around headlands, so routes should be planned with the tide. Water temperatures are cool, averaging around 17-18°C in the warmer months, typically requiring a wetsuit.
