About Rocky River Fishway
Rocky River Fishway is a small engineered fish ladder and low waterfall feature on the Rocky River on the Avalon Peninsula of Newfoundland and Labrador. It was constructed to assist migratory fish moving upstream and is located close to roadside access near Argentia/Placentia. The site is primarily of interest to people looking for fish runs, short nature stops, and local scenery rather than a large scenic waterfall.
Why This Waterfall Exists
Rocky River Fishway flows over layered sedimentary rock laid down about 539 million to 1.0 billion years ago. Over time, the stream has worn through these layers at different rates, creating the step that forms the waterfall.
Trail & Hike Details
The Approach
The easy 0.8-km out-and-back trail gains 67 metres of elevation on the way to the falls.
Trail Description
There is no developed hike to reach the fishway, it is essentially a roadside feature visible from a short walk from where you park. Visitors may need to step down a short, possibly unmaintained bank to the water's edge to get closer views of the ladder and low falls. Surfaces can be uneven, muddy, and slippery when wet.
What to Expect
Expect a modest river channel with a constructed fishway (series of stepped pools or concrete channels) and a low waterfall rather than a tall scenic cascade. Facilities are minimal or non-existent (no visitor center, restrooms, or maintained trails). Vegetation typical of Newfoundland river corridors (alder, spruce, marshy grasses) and seasonal insects in summer. During spring and early summer you may observe migratory fish activity (salmon/sea trout) and increased flows; in winter the area can be icy and covered in snow.
Accessibility
The trail is not wheelchair accessible. Uneven terrain and elevation changes require steady footing.

When to Visit
Spring and early summer are often the best times to visit for observing fish runs and higher flows. Summer offers easier access for viewing and photography. Fall can provide pleasant foliage and lower visitor numbers. Winter access is possible but expect snow/ice and limited visibility of fish activity.
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
Watch for slippery rocks and steep or unstable banks. Currents near and below fishway structures can be unexpectedly strong. There may be no cell coverage in some spots; let someone know your plans if you travel into remote areas. Beware of insects in summer and dress appropriately for rapidly changing Newfoundland weather. If visiting in winter, expect icy conditions and limited access.

Visitor Tips & Gear
• Wear sturdy, waterproof footwear, banks and access points can be muddy and slippery. • Use caution when approaching the water; rocks are slick and currents can be stronger than they appear. • Bring insect repellent in summer. • There are likely no services on site, bring water and snacks if needed. • Respect private property and posted signs; stay off any fenced or posted infrastructure. • Check local sources (municipal or provincial websites) for temporary closures or maintenance work that may restrict access.
