Grand Otway National Park is actually a vast area of primeval tropical rainforest forest. Driving out of the Apollo Bay on Ocean Road, it soon entered the National Park, which is just a few dozen kilometers away. The park is open and has no entrance. The park's most famous attractions are Cape Otway Lighthouse and Otway Fly Treetop Walk (or adventrues), but one is more than a dozen kilometers south of Ocean Road and one is more than a dozen kilometers north of Ocean Road. Cape Autway Lighthouse is ticket-free, with Australia's oldest lighthouse and beautiful seascape. Walking on the top of a tree is a pedestrian walk between trees up to tens of meters, which is also charged, but it is very exciting to walk. Especially, there is an iron tower, climbing to the tower, the tower gently swaying with the wind, which makes my fear of heights even more terrible.
