Most of us have been to the beach. We've enjoyed the sunshine, the beautiful blue water and the building of sand castles. But what about a visit from a cow? Or an airplane? No? Well, it's time you visited some new beaches. Read below to find some of the most unique, stranges beaches from around the world.

1. Perran Sands, Cornwall

This should be called LEGO beach since every day hundreds of LEGO pieces wash up on Perran Sands in Cornwall. This phenomenon is due to a huge wave that hit a container ship in 1997, sending tonnes of its cargo overboard. You can visit the Facebook page Lego Lost at Sea to see more. Perran Sands, Cornwall

2. Papakolea Beach, Hawaii

The sand on this beach comes in green. The reason – the presence of the mineral olivine. There are only three other green beaches that can be found in Guam, the Galapagos and Norway. Papakolea Beach, Hawaii

3. Hot Water Beach, New Zealand

Set on the Coromandel Peninsula, this beach has the seaside equivalent of underfloor heating. Subterranean hot springs filter up through the sand and visitors can burrow down and create their own hot-water pool to soak in.Hot Water Beach, New Zealand

4. Cow Beach, Goa, India

The name says it all – Cow Beach. Visitors to this beach can lay back, read a book and wait for a visit from several cows that wander freely among the beach.Cow Beach, Goa India

5. Maho Beach, St Maarten

You can lay on this beach and almost feel like you can touch an airplane. That's because plans almost land right on the beach. It's located just metres from Princess Juilana International Airport, making it a plane spotter’s paradise. Its Sunset Beach Bar even reportedly has a speaker that broadcasts transmissions between pilots and the airport's control tower.Maho Beach, St Marrten

6. Loango National Park, Gabon

This national park extends all the way to the beach, allowing elephants, buffalos, wild pigs, gorillas and hippos to take a dip in the ocean. Loango National Park, Gabon

7. Hyams Beach, Jervis Bay, Australia

If it's white sand you're looking to relax on during your next trip to the beach, this is the one for you. In fact, The Guinness Book of Records has recognized the sand here as the world's whitest. Hyams Beach, Jervis Bay, Australia

8. Bowling Ball Beach, California

Can't decide to go out for a day of bowling or to the beach? Why not do both at Bowling Ball Beach? This beach is littered with boulders that resemble giant blowing balls. Bowling Ball Beach, California

9. Glass Beach, California

In the 1900s people who lived in the coastal California town of Fort Bragg threw their garbage onto their local shoreline, dubbing it as 'The Dumps.' In 1967, the area was closed for a clean-up. But the ocean's waves wore down all the leftover glass into smooth, multi-coloured trinkets that can be found along the beach. The beach reopened in 2002 and is now a popular tourist attraction. Glass Beach, California

10. Zlatni Rat Beach, Brac, Croatia

This beach changes all the time – literally. The narrow beach extends about 300 yards into the sea and actually changes size and shape depending on the currents. Zlatni Rat Beach, Brac, Croatia
