Bosumarne Falls

Bosumarne Falls is near Chilliwack Lake, British Columbia, along Chilliwack Lake Road. The name appears neither in the BC Geographical Names database nor in the Canadian Geographical Names Database (searches of October 27, 2026). According to A Walk and a Lark, there is no sign or official trailhead for the falls.

Vancouver Trails describes a 2.5 km out-and-back with 75 m of elevation gain and about 1 h of walking, in season from April to November: it follows an old logging road, then climbs through forest to the pool below the falls. A Walk and a Lark gives 2.6 km, about 100 m of elevation gain and 40 to 50 min instead. The small lower falls is about 20 m past the forest edge according to Vancouver Trails, and under 50 m according to A Walk and a Lark. The main falls has two tiers carved into the cliff, with a plunge pool at its base (A Walk and a Lark).

A creek crossing is reported. Vancouver Trails describes a log bridge with no railings that is very bouncy, and a rugged, slippery upper section; A Walk and a Lark says the bridge was down in 2023 and advises against the trail when the water is high. Vancouver Trails adds that camping is not permitted and there are no toilets; dogs are allowed, but the bridge and upper section are hard going for them. Neither source names a land manager: check before your outing.
