Amazing Geological Sites on the Tasman Peninsula

Amazing Geological Sites on the Tasman Peninsula

The rugged Tasmanian coastline lends itself to the formation of amazing geological sites, with many grouped together on the Tasman Peninsula.

Tessellated Pavement

Best accessed at low tide, the tessellated pavement at Eaglehawk Neck resembles human-made pavement. During our visit it was raining, and the tide was still going out, but we were still able to walk over most of the pavement.

A tessellated pavement is formed near the shore when fractures in the rock are eroded, forming polygons. These formations are rare, and the one at Eaglehawk Neck is one of the best examples found worldwide.

Accessing the pavement is via a staircase which leads from a carpark via a viewing platform. When walking on the rocks, be careful because the algae that grows on them is very slippery.

A café located above the carpark was a great place to have a coffee and something to eat to escape the rain once we had explored.

Tasman Arch

Once a sea cave whose roof has collapsed, Tasman Arch forms an amazing natural arch over the rocks and sea below. A large carpark provides easy access to the area and a walking track allows you to walk around both sides. Viewing is great from the safety of the surrounding fence, so don’t climb them, the cliffs are very high.

The Blow Hole

Only a short drive from Tasman Arch the Blow Hole is another collapsed sea cave. When the sea is rough, or the tide is high, water is sprayed high into the air. A nearby carpark provides easy access to the blowhole, which is only a short walk away.

Remarkable Cave

A narrow sea cavern, Remarkable Cave looks spectacular at low and high tide.

Steps lead down to the cave from the large carpark. On the way down, there are several places where you can admire the views. From the platform, the long thin cavern is amazing, and you can watch the waves wash in, while you remain safe and dry.

A viewing platform near the carpark provides views of the rugged coastline surrounding the area.

What Did We Think of the Amazing Geological Sites on the Tasman Peninsula?

Tasmania’s natural beauty is a major drawcard for tourists and the Tasman Peninsula has some excellent examples. These amazing sites are accessible without difficult walks, enabling people to see some of nature’s wonders. All of them were great to see and highly recommended.

Ghosties Beach and the Rainbow Cave

Looking Out the Sea Cave Entrance

Ghosties Beach and the Rainbow Cave

Getting There and Parking

Located in Catherine Hill Bay South of Newcastle, Ghosties Beach and the Rainbow Cave (also called Ghosties Beach Cave) are an amazing place to visit, because of their beautiful colours and setting. We parked near Moonee Beach, as we were also visiting the Pink Cave. Parking is limited near the beach access trail, as the road is narrow. However, a small area of the one-way road is wider to allow cars to park. A sign indicates the way to the beach.

Moonee Beach

At the end of the track, you come out at Moonee Beach, an 800m long sandy beach with rock platforms at each end. At 800m long, there is plenty of room for everyone, so it’s unlikely to get crowded. Swimming is not advised, because the beach is not patrolled. While there we saw a lot of marine stingers washed up on the sand, which we were careful not to step on. Be careful, as the sting can still work even if they are dead. This is another reason to be careful swimming here.

Ghosties Beach

Ghosties Beach is to the south of Moonee Beach, which is an enjoyable walk, being 1600m to the cave entrance. At the south end of Moonee Beach is Flat Rocks Point, which has some interesting rock formations near the water’s edge. Walk over the sand dunes and down to Ghosties on the other side. Here you will find a lovely, secluded beach, with tree covered cliffs. One section of the beach has green algae covered boulders, which look amazing.

Next to the boulders, is a small rock outcrop has a coal seam exposed, with its black colour contrasting to the yellow sand.

The Rainbow Cave

A fissure in the cliff at the south end of the beach marks the entrance to the Rainbow Cave, making it easy to find. Only access the cave at low tide, otherwise it is too dangerous to enter. Check the tide times before you go, to make sure the tide it low.

The fissure leads into a sea cave with amazing rock colours, because of the way they have been eroded. From inside the cave, you are able to look out of the sea cave over the ocean and the nearby cliffs.

There is another sea cave further to the south but even at low tide it was too dangerous to enter.

What Did We Think?

This was a great place to visit, because of the amazing colours of the cave and the beautiful views along the beach. Remember to only visit at low tide.

Another great place to visit is the Pink Cave on the Moonee Beach Rock Platform

Moonee Beach and the Pink Cave

Getting There and Parking

Located in Catherine Hill Bay South of Newcastle, Moonee Beach and the Pink Cave (also called Deep Cave Bay) are an amazing place to visit, because of their beautiful colours and setting. Parking is limited near the beach access trail, as the road is narrow. However, a small area of the one-way road is wider to allow cars to park. A sign indicates the way to the beach.

The Track Down to the Beach

A sandy trail leads down to the beach, winding through bush until it reaches the beach. The beach is beautiful and quiet, making it a great place to relax and enjoy the sand and waves.

Moonee Beach

At the end of the track, you come out at Moonee Beach, an 800m long sandy beach with rock platforms at each end. At 800m long, there is plenty of room for everyone, so it’s unlikely to get crowded. Swimming is not advised, because the beach is not patrolled. While there we saw a lot of marine stingers washed up on the sand, which we were careful not to step on. Be careful, as the sting can still work even if they are dead. This is another reason to be careful swimming here.

Rock Platform

The rock platform on the north end of the beach is where you will find the pink cave. Access to the cave is only safe at low tide, so make sure you check tide times before you go. Walking across the rock platform can be slippery, so have good footwear and take care.

On your 700m walk to the cave, take time to look at some of the wonderful rock pools, as some are very colourful. Also look at the algae and seaweed growing on the exposed rocks, many of them are also brightly coloured.

The Pink Cave

Remember to only go here at low tide, because this is the safest period, as well as ensuring you see the pink rocks. The rocks are wet and slippery, because the cave is tidal, so take care.

Inside the cave, where the waves wash in, you will see the amazing pink rocks. Fully exposed at low tide, they make a great sight.

What Did We Think?

This was a great place to visit, because of the amazing colours of the cave. The beach is a great place to relax and enjoy you surrounding, either before or after the walk along the rock platform.

A great addition to this visit is the Ghosties Beach Cave, which is only 1600m away along the beach.
