Spectacular views reward those who climb up from the Captain Cook Lookout on the Cape Byron Walking Track. Ribboning around the headland and through rainforest, the track dips and (mostly) soars its way to the lighthouse. Look out for dolphins (year-round) and migrating whales (June to November). Allow about two hours for the entire 3.7km loop.
You're also likely to encounter bold brush turkeys and shyer wallabies.
