Lagos beaches, Algarve, Portugal- contributed by myself

Lagos is the most stunning choice for your vacation at the southern coast of Portugal. Almost every beach in this pretty town holds marvelous caves. It’s a true wonder walking here and escaping the waves as the caves connect the area. The charming tranquility of Lagos belongs to its beaches making it perfect for all ages and tastes.

The easiest way to explore Lagos beaches is to take a boat tour, though you can also do kayaking here.

The best beaches in Lagos

Praia de Batata is the closest beach to the city following Praia dos Estudantes and Praia do Pinhao. It’s the busiest in summer and excellent to meet locals. Being full of seashells is another reason to its charm. Different sports activities fill the beach during the summertime, such as volleyball, handball or snorkeling.

Praia do Camillo is a picturesque beach staying in the shelter of several cliffs. The big waves are not common here so it’s pretty suitable for families. The wooden stairs lead to this lovely beach, where you can enjoy stunning sunsets. Renting a kayak is also very popular here.

Meia Praia is the largest beach in Lagos stretching to 4 km and thus becomes less crowded. The cliffs of Ponta de Piedade create a shelter from the waves.

Donna Anna is an iconic beach of Lagos, only 10 minutes drive from the centre. The pretty stairs that lead to the beach make it so Instagrammable.

Ponta da Piedade is an isolated beach staying in the embrace of impressive cliffs.

Benagil Cave is nestled between Lagos and Albufeira, more precisely about 40 km from Lagos. The only way to reach the cave is by boat or kayak. Benagil is such a lovely village and the cave represents the precious symbol of the Algarve.

Monsul Beach, Spain- contributed by Linn Haglund of Amused by Andalucia

Monsul Beach in the beautiful Cabo de Gata Natural Park in southern Spain is one of the most beautiful beaches in Almeria. The local artist David Bisbal first discovered it during filming the music video of his top hit “Ave Maria”.

It is perfectly stretches between cliffs where hidden coves and caves hide beautiful coastal walks. You can recognize it by a giant rock dividing the beach in two and creating some natural shade. Besides, its fine sand meets the cascading sand dunes of the desert next to it. There are no facilities on Monsul Beach as it is within protected area.

How to reach?

You can reach it by car (there are a few parking spots by the beach) or on foot from the tiny village of San Jose. In the summer months, there is a fee of 5 Euros to enter by car. It’s the fact that only a restricted number of cars can enter the beaches beyond San Jose. This includes Los Genoveses Beach too, which is another of the popular beaches in the area.

Because of the popularity of the beaches, there is a bus service in the summer months. Walking takes about an hour from San Jose. It is not advisable in summer as it is scorching hot and there is minimal shade on the road.

Cala Gororitz, Sardinia- contributed by Chris Heckmann of Around The World With Me

One of the most stunning cliff-entrenched cove beaches in the world is Gala Gororitz on the Italian island of Sardinia. Cala Gororitz is one of the most beautiful beaches in Italy, surrounded by the dramatic coastal mountains of Gulf of Orosei National Park. It allures the east coast of the island.

The island of Sardinia fascinates with hundreds of amazing beaches, with incredibly clear and still water.

The beach is small, as most cove beaches are, so get there early so you can pick the best location. Sardinia is still relatively unknown outside of Europe, so you won’t be overrun with American tourists like elsewhere in Italy. But it’s a super popular domestic destination for Italian holidaymakers, so avoid the month of August if you can. 

How to reach?

What makes Cala Gororitz stand out is its unique location tucked away between jagged mountain peaks. It’s completely cut off from the road network of the island, and requires a 7 km round trip hike through the mountains to reach. Alternatively, you can take a boat tour to Cala Gororitz. The hike is not too difficult, and when you get your first view of the beach it will all be worth it. 

As you’re enjoying beers on the beach – or whatever it is you carried with you – just remember that you have to hike 3.5km back to the parking lot, mostly uphill. There are no services at the beach so carry out all your garbage. You will need to leave only your memories of one of the most spectacular beaches in the world.

Reynisfjara, Iceland- contributed by Jessica Schmit of Uprooted Traveler

Reynisfjara Black Sand Beach is inarguably the most famous beach in Iceland. The unique columnar basalt cliffs, jagged sea stacks, and inky black sand characterise this awesome beach. It stretches along the southern shore of Iceland in the small town of Vik. This beach is so otherworldly-looking that it was used as a filming location in the beloved Game of Thrones series.

You’re welcome to explore inside the cave throughout the day, but be careful! Reynisfjara is known for its infamously strong waves and dangerous undercurrent, which have unfortunately killed a number of visitor. That’s why be sure to keep an eye on the rising tide level while you’re exploring the cave.

What else to see

Reynisfjara also happens to be home to the Hálsanefshellir Cave, an impressive cave comprised of columnar basalt, located towards the eastern part of the beach. The cave is not terribly deep, but it is quite tall, making this an unmissable photo stop while you’re in Iceland. 

If you’re visiting during the summertime, be sure to keep a lookout on the cliffs above Hálsanefshellir, which serve as a nesting ground for puffins. You may just see these adorable clowns of the sea and their young (known as pufflings!) diving overhead from Hálsanefshellir to go fishing into the chilly Arctic waters.

Railay Beach, Thailand- contributed by Catherine from Nomadicated

Located just a quick ferry ride away from the city of Krabi in Thailand, Railay Beach awaits. Turquoise waters glisten around pristine sandy beaches hugged by dramatic limestone cliffs and caves. 

Railay Beach is renowned for its distinctive cave beaches, formed by centuries of erosion. These caves serve as a playground for rock climbers and a platform to view the surreal, dramatic karst formations surrounding the bay.

Which caves to see

Although many mini caves dot all over the seascape, the Phra Nang Cave and the Diamond Cave are two of the most famous at Railay Beach. Adorned with intricate stalactites and stalagmites, Phra Nang Cave has hidden canals leading to panoramic views of both Phra Nang and Railay Beach. On the other hand, the Diamond Cave is a large cavern famous for its sparkling mineral formations that resemble glittering diamonds.

Another iconic landmark at Railay Beach is the Phra Nang Shrine, a small cave dedicated to a mythical sea princess. This sacred site is adorned with colorful ribbons and wooden carvings, adding a touch of local culture and folklore to your visit.

Railay Beach is accessible only by boat. Many fly to Phuket first, then take long-tail boats from Krabi Town or Ao Nang, an approximately 15-20 minute journey.

Broken Beach, Indonesia- contributed by Victoria Heinz of Guide Your Travel

Broken Beach is a stunning natural attraction on the western coast of Nusa Penida Island in Indonesia. What makes this place so special is the unique formation of a natural archway created by the erosion of limestone cliffs over time. The archway forms a circular lagoon surrounded by towering cliffs, with the ocean stretching beyond. The view from the top of the cliffs is breathtaking and definitely worth the trip.

Once you reach Broken Beach, you can take in the breathtaking views of the rugged coastline, towering cliffs, and crystal-clear waters below. The lagoon, surrounded by steep cliffs, provides a safe haven for various marine life. Visitors often spot manta rays swimming gracefully in the waters, adding to the place’s allure.

Cat Ba Island, Vietnam- contributed by Clotilde Passalacqua of A Princess Travelling With Twins

Everybody organizing an itinerary to visit Vietnam knows that a cruise to see the impressive Halong Bay is a must. Even if you don’t have 2 or 3 days for a longer cruise, a day cruise will still enchant you. However, there is somewhere possibly even better than Halong Bay and that is Lan Ha Bay, which is just a quieter and less touristic part of the bay.  

The sea caves around Cat Ba Island are a testament to the geological wonders of nature that have shaped them over the years by the relentless forces of the ocean.

Dark Cave (Hang Toi) and Light Cave (Hang Sang) are just two of these incredible caves. As their names suggest, Dark Cave is characterized by its dim interior and your cruise operator will probably give you a headtorch for safety, while Light Cave is illuminated by natural sunlight streaming through small openings. Both caves showcase remarkable geological formations.

How to reach

Access to Lan Ha Bay is from Cat Ba Island, the largest island in Halong Bay. The island itself is home to a dense jungle, pristine sandy beaches, and an array of astonishing sea caves waiting to be explored.

Taking a cruise around the island not only offers breathtaking panoramic views but also enables access to some of these fascinating sea caves. Many of these hidden gems can only be visited via kayak, rowing boat, or by swimming, allowing for an intimate and exhilarating experience.

Ha Long Bay, Vietnam- contributed by Michelle from Intentional Travelers

Hidden among the captivating limestone islands of Ha Long Bay, Vietnam are countless caves and hidden beaches. Most are only accessible by boat and usually visited via overnight cruise or day tours.

One of the most famous caves is known as “Surprise Cave,” boasting massive chambers, crystal-clear waters, and unique rock formations. This one is popular with cruises and can get crowded.

Nearby Trinh Nu cave sees far fewer crowds because limited visitation is enforced. The cave is named after a tragic love story involving a young girl turned to stone. 

What to see

Visitors can explore the cave’s interior with its intricate stalactites and stalagmites. Tinh Nu beach is perfect for swimming, sunbathing, and kayaking to surrounding islands.

Even exploring off the beaten path in Ha Long Bay, whether by tour or kayak rental, gives visitors access to smaller, unnamed cave beaches throughout this magical world heritage site.

Cathedral Cove, Coromandel Island, New Zealand- contributed by Tina Riegelnegg from Veganderlust

Everyone travelling to New Zealand knows the famous cathedral cove on Coromandel on the North Island of New Zealand. But the South Island has its own cathedral cove in the Catlins National Park and it’s just as impressive. It’s difficult to get there by public transport. But you can easily include it in your van life itinerary for the South Island. 

The cave is inside a gigantic rock formation and can only be visited during low tide. What makes this cave special is that the entrance and the exit are not the same. You might need to use the flashlight on your phone to walk around a bend in the cave before reaching the light from the exit. And if you’re lucky, you might even spot some penguins near the cave! 

What else to see

There’s a small entrance fee to pay at the parking lot to see this beautiful landscape. From the parking lot, it’s a short walk through an amazing forest full of native fern trees. After the walk, you’re rewarded with a gorgeous beach, which you can stroll along until you reach the cathedral cove. After visiting the cave you can go for a swim in the ocean or relax on the beach.

San Diego Sunset Cliffs & Hidden Caves, USA- contributed by Kate from Kate Roams The World

In the ever popular Southern California city of San Diego, there is still one hidden gem to discover!

This open ceiling sea cave in Sunset Cliffs is for the serious adventure seekers! 

Caution: To go into the cave, you must be sure there is a negative tide since you’ll have to walk a little bit in the ocean. I went at a negative tide and the water still came up to my knees. So if it’s not a negative tide, the water would be above your head and not safe.

How to reach

Find the entrance to the cave by parking near Luscomb’s Point in Sunset Cliffs. You’ll notice the fenced off area, this is bordering the open ceiling of the cave. 

Look to the right of the cave while you’re facing the fenced off area to Luscomb’s Point. This is a popular spot where surfers will frequently traverse down. 

The hike to the cave is a very short one, but you first must scale down a sandstone rock wall. There is a spot in the sandstone where you will see faint stairs or steps carved into the rock- this is the path you will take. Use caution, this can be very slippery. It is best to have someone below you to guide your footing. 

Next you will hug the cliff and walk into the ocean towards the cave for 50-100 yards. Use caution as the rocks underneath can be extremely slippery! 

Once inside, spend a little time hanging out and taking photos of this epic open ceiling cave before heading back up. But be careful not to spend too much extra time here and keep track of the tide!

Devils Punch Bowl, Oregon, USA- contributed by Alec from Exploring With Alec

Just South of Lincoln City, Oregon, is the spectacular Devils Punchbowl State Natural Area. Nestled on the Oregon Coastline, the Devil’s Punchbowl is a massive circular sea cave that looks impressive from the top and downright incredible from within. 

Visitors can hike into the Devils Punchbowl during low tides and gaze up at the wild rock formations. Thanks to millions of years of erosion, the insides are truly mind-blowing! Additionally, make sure to check out the tidepools on the north side of the sea cave. Furthermore, bring those binoculars because you might spot a humpback or grey whale migrating north or south.

How to reach

Curious how to get here? Devils Punchbowl is on the central Oregon coast, about two and a half hours from Portland and 30 minutes from Lincoln City. It’s perfect for stretching your legs, soaking up the sun, and enjoying the beautiful ocean views.
