Just downstream from Winifred Falls, the South West Arm Pool is one of the most tranquil swimming holes in Royal National Park. Surrounded by bushland and sandstone, it’s a calm section of the river where visitors can swim, picnic, and enjoy the peaceful setting.

Why Swim at South West Arm Pool?

• Calm swimming: The wide pool is great for a refreshing dip on a hot day.

• Bushland setting: Gum trees and sandstone cliffs create a secluded vibe.

• Close to Winifred Falls: Many walkers combine both locations in one trip.

• Less crowded: Fewer visitors than the main falls, giving you space to relax.

South West Arm Pool and Winifred Falls

The South West Arm Pool sits just downstream from Winifred Falls. After tackling the Winifred Falls track, many visitors continue along the creek to reach this peaceful pool.

It’s worth linking both spots together for a full day’s adventure — start with the waterfall, then cool off in the larger, calmer pool below.

How to Get to South West Arm Pool

• By Car: Park along Warumbul Road, Royal National Park, near the Winifred Falls track entrance.

• The Walk: Hike to Winifred Falls (approx. 1.5 km each way). From the base of the falls, follow the creek downstream for a short walk to reach the South West Arm Pool.

• Trail Conditions: The track is uneven and can be slippery after rain. Wear sturdy shoes and take care near the water’s edge.

📌 For official park information, check the NSW National Parks and Wildlife Service.
