For a first visit to Campbell Valley Regional Park, the Little River Loop is a route you can plan around. Metro Vancouver lists it as 2.3 kilometres and suggests allowing about an hour. The loop crosses the Little Campbell River twice.
The regional park brochure describes the route as generally flat and wheelchair accessible. The nearby Ravine Trail is a different outing, with a steeper section. If the Little River Loop is your goal, follow the named route rather than choosing a trail just by its length.
The park has several entrances. Use the official map to pick a meeting point and check current park hours before leaving.
