Baie de Penouille is a coastal bay forming part of the Gulf of St. Lawrence within Parc National de Forillon on the Gaspé Peninsula. It is a saltwater feature characterized by a marshland ecosystem and a long, sandy beach known as Plage de Penouille. This beach serves as the primary access point for paddlers, offering a natural launch and take-out area directly onto the bay. The bay is sheltered from the open ocean by the Presqu'île de Penouille, a narrow peninsula. A notable geographical feature is the Taïga trail, a wooden boardwalk and path that follows the cordon littoral, or coastal barrier, separating the bay from the Atlantic Ocean, passing over a marshy area. This creates a distinct paddling environment where calm, protected bay waters contrast with the nearby open coast.

The overall character is one of a protected, scenic coastal area rich in wildlife. The bay and surrounding marsh are part of a protected area recognized for its biodiversity, where paddlers may observe seals and a variety of seabirds. The water body is adjacent to significant historical sites, including the Fort-Péninsule area and an Amerindian site at its northeastern limit. For trip planning, paddlers should be aware of the bay's proximity to the public port and shipping lanes of the Havre de Gaspé, as defined by official regulations, indicating the potential for commercial boat traffic in the broader area. The best seasons for paddling are typically summer and early fall, coinciding with warmer weather and calmer coastal conditions. Facilities are limited to the parking area at Plage de Penouille.
