On the escarpment behind Ulladulla, the distinctive dome of Pigeon House Mountain - Didthul to the Yuin people - rises from the forest of Morton National Park. The walk climbs steeply through heath and forest to a series of steel ladders that scale the final rock cap, emerging on a summit with a vast view over the wilderness of the Budawang Ranges and out to the sea. It is a short but demanding climb, the ladders not for the faint-hearted, and the payoff among the finest on the south coast. Cook named the peak from his ship in 1770.
