Jervis Bay Caves and Sea Caves: Cathedral Rocks, Tours, and Exploration

Carved by Millennia of Southern Ocean Swell

The coastline around Jervis Bay isn’t just white sand and turquoise water. At its edges — the headlands, cliff faces, and rocky platforms — the sandstone and siltstone have been carved by waves into an extraordinary landscape of sea caves, arches, overhangs, and sculpted rock formations.

Some of these caves are accessible on foot at low tide. Others require a kayak or boat to reach. A few are best appreciated from the water looking up at sheer cliff faces. All of them add a dimension to Jervis Bay that most visitors never discover because they never leave the beach.

Cathedral Rocks

Cathedral Rocks is the headline act. Located on the southern side of the bay near the entrance to Booderee National Park, this formation is a series of towering rock pillars and deep overhangs that rise from the waterline. The name is apt — the scale of the rock faces and the way light filters through gaps and archways genuinely evokes a cathedral interior.

How to See Them

By kayak is the best way. Paddling into the Cathedral Rocks area at water level lets you appreciate the full scale of the formations. On calm days, you can paddle right into several of the larger overhangs and through narrow channels between rock pillars. The water beneath you is often crystal clear over a sandy bottom, with fish darting between the rocks.

Several operators run guided kayak tours that include Cathedral Rocks as a highlight. These typically depart from Huskisson and paddle south along the coastline, taking 2–3 hours round trip. Guides know the best routes through the formations and can time visits with tide conditions.

By boat, Cathedral Rocks is visible on many of the bay cruise and boat tour routes. You won’t get as close as in a kayak, but you’ll see the full sweep of the coastline and the formations in context. Some operators run dedicated coastal exploration tours that spend more time around the rock formations.

On foot, you can view Cathedral Rocks from above via coastal walking tracks in the Booderee area. The perspective is different — you’re looking down at the formations rather than up — but the combination of cliff-top views and deep blue water is spectacular. Check our Booderee National Park guide for trail access details.

Best Conditions

Calm, low-swell days are essential for kayak access. Any significant wave action makes the area around the rocks dangerous — water surges through channels unpredictably and can push a kayak into rock. Tour operators cancel in marginal conditions, and rightly so.

The ideal visit: a calm morning with a rising tide. Rising tide means water levels are coming up, giving you more clearance through channels and under overhangs. Morning light from the east illuminates the rock faces beautifully.

Other Sea Caves Worth Exploring

Cathedral Rocks gets the attention, but Jervis Bay’s coastline has dozens of smaller caves and formations scattered along its rocky sections.

Point Perpendicular Sea Caves

The cliff face at Point Perpendicular — the northern headland of the bay — drops 100 metres vertically into the sea. At the base of these cliffs, wave action has carved deep caves and tunnels into the sandstone. These are boat-access only and only approachable in very calm conditions due to the exposed position and reflected swell off the cliff face.

From the clifftop, you can peer down and see the cave entrances. The scale is humbling. Experienced sea kayakers sometimes paddle this section, but it’s genuinely advanced — strong currents, reflected waves, and no easy bail-out points.

Steamers Beach Caves

On the ocean side of Booderee, Steamers Beach is backed by low cliffs with several walk-in caves and deep overhangs accessible at low to mid tide. The beach itself is wilder and more rugged than the sheltered bay-side beaches. Walk south along the sand at low tide and you’ll find cave openings in the cliff base, some extending several metres back into the rock.

These are straightforward to explore on foot — no special equipment needed beyond common sense and an eye on the tide. Don’t venture into any cave at incoming high tide or in heavy swell.

Murrays Beach Rock Formations

Murrays Beach, inside Booderee National Park, has sculpted rock platforms and small overhangs at its southern end. These aren’t deep caves, but the weathered sandstone forms are photogenic and the rock pools beneath them are excellent for exploring. At low tide, you can scramble around the headland to discover hidden crevices and channels.

Plantation Point Overhangs

At Plantation Point near Vincentia, the rocky platform extends out with several low overhangs and crevices at water level. These are popular with snorkelers — the overhangs create shaded habitat that attracts marine life, including wobbegong sharks that rest on ledges during the day. You can swim into some of the larger openings in calm conditions.

Guided Cave and Sea Cave Tours

Going with a guide is the best way to experience the sea caves, especially if you’re not an experienced paddler or don’t know the coastline.

Kayak Tours

The main operators running sea cave kayak tours from Huskisson include:

Jervis Bay Kayak and Paddleboard Co. — runs a dedicated sea cave and Cathedral Rocks tour. Small groups, knowledgeable guides, all equipment provided. Tours typically last 2.5–3 hours and are suitable for beginners in calm conditions
Jervis Bay Wild — offers kayak eco-tours that incorporate caves and rock formations along with marine wildlife spotting

Expect to pay around $80–$120 per person for a guided kayak tour. Booking ahead is recommended, especially in summer and on weekends. Tours are weather-dependent and operators will reschedule or refund if conditions are unsafe.

Boat Tours

Several boat tour operators pass by the sea caves and rock formations as part of broader bay cruises. These are a good option if you want to see the caves without the physical effort of paddling. Dolphin watching cruises often swing past Cathedral Rocks and the southern headland formations.

Self-Guided Exploration

If you’re an experienced kayaker, you can hire kayaks and explore independently. Know the conditions before you go:

Check the Bureau of Meteorology marine forecast for swell height and wind
Understand the tides — explore caves on a rising tide so water levels don’t drop and strand you inside
Wear a PFD (life jacket) at all times
Tell someone your planned route and expected return time
Stay well clear of cave mouths in any swell — wave surge inside caves is amplified and unpredictable

The Geology Behind It

The rock around Jervis Bay is primarily Permian-age sedimentary stone — sandstone and siltstone laid down roughly 250–300 million years ago. Over geological time, tectonic uplift raised these rocks above sea level, and then the ocean went to work.

Wave erosion is selective. It attacks weaknesses — joints, fractures, softer layers within the rock. The caves form where waves have exploited these weaknesses, gradually hollowing out chambers along fault lines or softer bands. The arches and pillars you see at Cathedral Rocks are the remnants of harder rock left standing after softer surrounding material eroded away.

The process is ongoing. The caves are slowly enlarging, arches will eventually collapse to form stacks, and stacks will erode to stumps. What you’re seeing is a snapshot of a coastline in constant, slow transformation.

Photography Tips

The sea caves and rock formations are some of the most photogenic subjects in the bay. A few tips:

Timing matters. Early morning light (first hour after sunrise) gives warm side-lighting on east-facing formations. For Cathedral Rocks, morning light penetrating through gaps in the rock creates dramatic rays through sea spray.

Shoot from the water. A waterproof camera or phone case is essential if you’re kayaking. Shooting from water level with the cave roof overhead creates the most dramatic perspective. GoPro-style cameras on a chest or head mount work well for video while paddling.

Wide angle. Inside the larger formations, you need a wide-angle lens to capture the scale. Phone cameras are usually wide enough, but if you’re shooting on a dedicated camera, go as wide as you have.

Include a kayak or person for scale. The formations are impressive in person but can look flat in photos without a sense of scale. A brightly coloured kayak at the base of a rock pillar immediately communicates size.

Safety First

Sea caves demand respect. They look beautiful and inviting in calm conditions, but the marine environment changes quickly.

Never enter a sea cave in significant swell. Wave surge inside enclosed rock chambers is amplified and can slam a swimmer or kayak into rock walls with serious force
Watch the tide. Some walk-in caves flood completely at high tide. Know the tide times and give yourself a generous safety margin
Wear appropriate footwear. Wet rock is slippery. Reef shoes or sturdy sandals with grip are essential for scrambling around rock platforms
Don’t climb unstable rock. The sandstone is weathered and sections regularly fall. Don’t climb cliff faces or stand on overhangs
Go with a guide if in doubt. The guided tours exist for a reason. The operators know the conditions, the routes, and the risks. If you’re not experienced in coastal environments, this is money well spent

The caves have been here for thousands of years. They’ll be here after your visit. Take your time, respect the conditions, and enjoy one of Jervis Bay’s most underappreciated features.
