About Rainbow Falls
Rainbow Falls (coordinates 48.8468, -87.3998) is a freshwater waterfall on a tributary feeding into the Lake Superior watershed in northern Ontario, located roughly between the towns of Nipigon (≈44.3 miles) and Marathon (≈48.4 miles). Local reports indicate a scenic, natural cascade in a forested, rocky setting typical of Lake Superior’s north shore. Specific published measurements and formal trail designation appear to be limited; visitors should verify conditions locally before travel.
The Setting
Rainbow Falls sits at 284 metres within Rainbow Falls Provincial Park (Recreational Class), in the foothills of Ontario. The falls drop 24 metres.
Why This Waterfall Exists
Rainbow Falls flows over hard intrusive rock, primarily granodiorite and granite, laid down over 2.5-3.2 billion years ago. These resistant rocks form a durable ledge that water cannot easily wear away, creating a 80-foot drop where softer material downstream has already eroded.
Trail & Hike Details
The Approach
The moderate 1.9-km out-and-back trail gains 40 metres of elevation on the way to the falls.
Trail Description
There does not appear to be a widely maintained, named trail to this specific Rainbow Falls. Access is typically via a short, informal footpath from a nearby pullout or roadside access point. Expect uneven, rocky ground, tree roots, and possible wet/muddy sections. The approach may cross small stream channels and could require short bushwhacking if the path is not clearly worn.
What to Expect
The falls cascade 24 metres over hard intrusive rock.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.

When to Visit
Spring (late April–June) for highest flows and dramatic runoff. Summer (July–August) for easier access and warmer conditions. Fall for foliage and reduced insect activity. Winter visits can offer frozen, photogenic scenes but may require winter travel experience and traction devices; ice and snow make approaches hazardous.
Seasonal Access
The best time to visit is Spring, Summer, Fall, and Winter. Check with the managing park or local authority for current conditions.
Safety Information
Hazards include slippery bedrock, fast or cold water, hidden submerged objects, unstable banks, and limited safety infrastructure (no railings). Weather can change quickly; hypothermia is a risk even in summer if you get wet. Cell phone coverage may be unreliable, notify someone of your plans and expected return time. Wildlife encounters (including bears) are possible, store food securely and follow local wildlife guidance. Use caution on winter ice and avoid approaching edges of frozen waterfalls where ice can be unstable.
