Lower Gledhill Falls – A Hidden Waterfall in Sydney’s Northern Beaches

Lower Gledhill Falls – A Hidden Gem in the Northern Beaches

Tucked away in Ku-ring-gai Chase National Park, Lower Gledhill Falls is one of the most underrated waterfalls in Sydney’s Northern Beaches. This peaceful spot features a cascading drop into a wide pool below, perfect for adventurous swimmers and nature lovers looking for somewhere off the beaten path.

If you’re keen to explore more hidden waterfalls and swimming holes like this one, my guide Swim New South Wales includes detailed directions, maps, and insider tips.

Exploring Lower Gledhill Falls

The main attraction at Lower Gledhill Falls is the larger lower pool, where the waterfall drops into a natural basin surrounded by bushland. On calm days, the water has a turquoise hue, but after heavy rainfall it often turns a deep brown as runoff flows through the gorge.

Above the main waterfall is a smaller tier, featuring a mini waterfall and a shallow pool that’s about shin-deep at its deepest. While you can’t really swim here, it’s still a beautiful place to sit, dip your feet, and enjoy the sound of water spilling over the sandstone.

Swimming at Lower Gledhill Falls

Swimming conditions at Lower Gledhill Falls vary with the seasons. After spring rain, the water can appear dark and murky, but in summer — when conditions are drier — the pool often clears to a refreshing aqua tone. This makes it a favourite among locals searching for a secret swimming hole in Sydney that feels wild and untouched.

Because the lower section can be tricky to access, it’s best to take care when climbing down. Wear sturdy shoes, and avoid visiting right after heavy rain when the rocks are slippery.

How to Get to Lower Gledhill Falls

Lower Gledhill Falls is located in Ku-ring-gai Chase National Park, around 45 minutes north of Sydney CBD. The track starts from McCarrs Creek Road, near the bridge over McCarrs Creek. From there, a short walking trail leads down toward the sound of rushing water.

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

Waterfalls in the Northern Beaches

Lower Gledhill Falls is just one of many waterfalls in Sydney’s Northern Beaches. Other nearby spots worth visiting include:

• Upper Gledhill Falls – a short walk upstream with another tranquil pool.

• Irrawong Waterfall – tucked into bushland near Warriewood.

• Flat Rock Waterhole – a quiet, lesser-known swimming spot in Ku-ring-gai Chase.

These hidden gems make the Northern Beaches an amazing destination for waterfall chasing, whether you’re after a quick dip or a scenic bushwalk.

⚠️ Safety at Lower Gledhill Falls

While Lower Gledhill Falls is stunning, it’s also a location that requires extra caution. At the track entrance you’ll find a warning sign noting that several deaths have occurred here. The lower pool can only be reached by scrambling down steep, uneven rock, which becomes extremely slippery after rain.

Because of this, I only recommend visiting if you are experienced and confident with bushwalks and rock scrambles. Always wear sturdy shoes, avoid the descent in wet conditions, and never attempt cliff jumps.

This is one of those hidden waterfalls in the Northern Beaches that rewards careful exploration — but your safety should always come first.
