Vancouver's seawall path includes a 9-km (5½-mile) paved shoreline section within Stanley Park. It's one of several car-free zones in the park and it's popular with walkers and cyclists. If you have the time (about a half day) and the energy, strolling the entire seawall is an exhilarating experience. It extends an additional mile east past the marinas, cafés, and waterfront condominiums of Coal Harbour to Canada Place in downtown, so you could start your walk or ride from there. From the south side of the park, the seawall continues for another 28 km (17 miles) along Vancouver's waterfront to the University of British Columbia, allowing for a pleasant, if ambitious, day's bike ride. Along the seawall, cyclists must wear helmets and stay on their side of the path. Within Stanley Park, cyclists must ride in a counterclockwise direction. The seawall can get crowded on summer weekends, but inside the park is a 28-km (17-mile) network of peaceful walking and cycling paths through old- and second-growth forest. The wheelchair-accessible Beaver Lake Interpretive Trail is a good choice if you're interested in park ecology. Take a map—they're available at the park-information booth and many of the concession stands—and don't go into the woods alone or after dusk.
