About Lower Bosumarne Falls
Lower Bosumarne Falls is a forested, mountain-stream waterfall located at approximately 49.106, -121.4907 in southwestern British Columbia, fairly remote from built-up areas. It sits in steep, densely treed terrain and is best-known to local hikers and backcountry visitors rather than as a developed park attraction. Water flow is seasonal and typically highest during spring snowmelt; access may require travel on unpaved forest or logging roads and route-finding on unmaintained trails. Exact waterfall height and official geographic details are not readily available and appear to be undocumented in major park listings.
The Setting
Lower Bosumarne Falls sits at 616 metres within Wildlife Habitat Areas, in the hills of British Columbia.
Why This Waterfall Exists
Lower Bosumarne Falls flows over layered sedimentary rock laid down about 23-66 million years ago. Over time, the stream has worn through these layers at different rates, creating the step that forms the waterfall.
Nearby Falls Worth Visiting
Greendrop Lake Falls (38 m) lies 5.6 kilometres to the northeast. Also nearby: Bosumarne Falls (25 m, 0.3 km) and Foley Lake Falls (20 m, 6.8 km).
Trail & Hike Details
The Approach
The easy 2.6-km out-and-back trail gains 76 metres of elevation on the way to the falls.
Trail Description
There does not appear to be a widely maintained, signed trail to Lower Bosumarne Falls. Visitors report routes that include travel on forestry roads followed by bushwhacking or travel on rough, unmarked footpaths through steep, forested terrain. Sections may be steep, muddy, and require scrambling over roots and rocks. Route-finding skills are likely required; expect no constructed viewpoints, handrails, or trail infrastructure.
What to Expect
Expect a natural, undeveloped waterfall setting with dense forest, wet and mossy rocks, and variable water flow. Spring and early summer typically provide the strongest flows; late summer and fall can be much lower. Terrain is steep and may include loose rock, slippery logs, and stream crossings. Facilities (toilets, trash cans, signage) are unlikely. Wildlife in the area may include deer and black bears; insects (mosquitoes, black flies) can be abundant in warmer months.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.

When to Visit
Late spring (snowmelt) for highest water flow and full cascades. Early to mid-summer is often drier but more accessible. Fall can offer lower crowds and good colors; avoid winter unless experienced with winter backcountry travel due to ice, snow, and avalanche risk in steeper terrain.
Seasonal Access
The best time to visit is Spring, Summer, and Fall. Winter access may be limited. Check with the managing park or local authority for current conditions.
Safety Information
Hazards can include steep, slippery, and unstable terrain; wet and moss-covered rocks; loose rock and tree roots; fast-moving water and strong currents near the falls; limited or no cell service; and seasonal road closures or poor road conditions. Flashy streams can rise rapidly in heavy rain, avoid getting too close to edges of waterfalls or unstable banks. Use caution in winter: ice and avalanche risk may be present in steeper or higher sections. Always follow Leave No Trace principles and err on the side of caution if conditions are uncertain.
