Detailed Insights

Praia do Cassino – Atop the South Atlantic, this Brazilian stretch earned its title in 1994 when the Guinness World Records acknowledged its length. Modern tourism, with approximately 150 000 annual visitors, revels in surf, sand‑dune exploration, and whale watching, while the 1966 solar eclipse launch by NASA engineers added a historic testament to the vicinity.

Cox’s Bazar – The southeastern monsoon coast of Bangladesh measures about 120 km, presenting an unspoiled shore that balances beach storms with tranquil dolphin sightings, yet remains a hidden jewel, rarely charted by international vacationers.

“Ninety‑Mile Beaches” – Two separate coastlines share the same moniker; the Australian version stretches roughly 144 km along Victoria, while the New Zealand counterpart spans around 88 km, both prized by surfers and photography devotees for their expansive horizons.

Unique Landmarks – Aside from pristine sands, Praia do Cassino features the stricken ship Navio Altair, the West Jetty, and a beloved Yemanja statue, while its corona hosts the world’s largest seal congregation, accessible via guided boat tours.

Key Concepts

  • Guinness World Record – An internationally recognized certification granted by Guinness for unparalleled achievements, such as the longest beach.
