Rainbow Falls

Overview

Rainbow Falls is a small, spring-fed coastal waterfall that spills over a colorful, algae-streaked cliff onto rock platforms at Station Beach. It’s a niche gem—more about moody Bass Strait scenery and the “rainbow” shimmer on sunny days than raw water power. The common route is roughly 4.7 miles total (out and back), with about 580 feet of rolling elevation through dunes and along soft sand. Expect wind, big sky, and a splashy payoff when recent rain juices the flow.

Route Options

Most hikers set out from the Bimbi Park/Station Beach access for the ~7.5–7.6 km return. Boardwalks thread coastal scrub to Station Beach; once on the sand, turn left (east) and walk about a mile to the rock platforms, then rock-hop to the base of the falls. An alternative begins at the Cape Otway Lighthouse carpark for an ~11.5 km return, passing lighthouse viewpoints and a historic cemetery before dropping to the beach. Either way, you return the same way you came.

Difficulty and Hazards

On paper it’s easy–moderate, but the angled, soft sand and slippery rock shelves make it feel tougher. The crucial factor is ocean conditions: this side trip is tide- and swell-dependent. Only go near low tide in benign surf—sections can be cut off quickly at higher water or in rough seas. The rocks around the falls are slick where freshwater runs. Station Beach is remote and unpatrolled, and swimming isn’t recommended.

What You’ll See

Expect wide-open Bass Strait views, wave-cut rock channels, and the algae-stained cliff that gives the falls their name. In bright afternoon sun you may catch a prismatic arc in the spray. Starting from the lighthouse adds historic flavor with cemetery headstones and occasional lighthouse glimpses.

Wildlife

Koalas are regularly spotted near the Bimbi Park approach. From winter into early spring, keep an eye offshore—Southern Right Whales sometimes cruise past. Birdlife patrols the beach and cliffs year-round.

Best Time to Hike

Flows are most reliable after steady rain, typically autumn through early spring (March–November). Summer visits can still be scenic, but the falls may shrink to a trickle. For photography, aim for a clear afternoon when the sun lights the cliff face—and only if the tide and swell line up.

Logistics

Park either at the Bimbi Park/Station Beach access or at the Cape Otway Lighthouse carpark. There are no toilets, bins, or water at the beach; pack out all rubbish and bring plenty of water, sun protection, and grippy footwear. Dogs aren’t allowed, and this can be an exposed, windy outing—layers help.
