Sheoak Falls–Castle Rock Circuit

This roughly 9.4 km circuit starts at Sheoak Picnic Area and links Garvey Track, the fern-lined Sheoak Creek valley, Swallow Cave, Sheoak Falls and Castle Rock lookout. Follow the creek and cave section to the falls, climb to the lookout, then return to the picnic ground on the woodland side of the circuit. Allow about 3–3.5 hours; the route has uneven creekside rock, a sustained climb and steep steps. Published figures round it to 9 km, while the detailed mapped circuit measures about 9.4 km.

The creek section crosses several small bridges and passes mossy rocks and fern banks. A short side track leads to Swallow Cave and Sheoak Cascades; retrace it to the main route. The stepping stones across Sheoak Creek are the key decision point: cross only when the water is low and the stones are safely passable. If the crossing is unsafe, turn back by the same route. After the crossing, steps lead down to the Sheoak Falls viewing platform; allow time for the climb back out.

The route climbs from the creek valley toward an old logging track, then branches onto the rough, steep Castle Rock spur. The lookout is reached by a 1.5 km return side trip with many steps. From the top, the Cumberland River mouth, Great Ocean Road and Southern Ocean open out below. Return along the same spur to finish the circuit.

The creek gullies and eucalypt forest are a quieter counterpoint to the lookout. Listen for Grey Fantails, Laughing Kookaburras and White-plumed Honeyeaters; koalas are possible in the surrounding trees but are never guaranteed. Toilets, picnic tables and gas barbecues are available at Sheoak Picnic Area. Dogs are not allowed in Great Otway National Park.
