Nestled in the Chilliwack River Valley, Chilliwack Lake Provincial Park boasts a beautiful lake and rugged mountain slopes covered with old growth forests. Approximately 25 miles of trails meander through the park, providing plenty of opportunities for hiking and wildlife watching, but cyclists and horseback riders are asked to stay on the roadways. The park's namesake lake is its biggest attraction, and it offers a day-use area with a sandy beach and a boat launch. The water is typically too cold to swim, but it's perfectly suited to boating, windsurfing, and canoeing, although the park recommends that only experienced paddlers go out on the lake.
