In its first 15 years of life, this outdoor festival has established itself as one of the most important events in the country, featuring some of the best performers in the world. Held in the city of Rio das Ostras, surrounded by golden sandy beaches, green hills and crystal-clear waters, the event offers 4 days of high-quality music.

At the summit of this 15th-century castle lies the world-famous Blarney Stone. Legend has it that those who kiss the stone will receive "The Gift of the Gab" — eloquence and charm. The lesser-known Poison Garden features a collection of deadly and dangerous plants from around the world, while the Rock Close and numerous outdoor statues and artworks inspire a broader view of history. You'll also stumble upon a fern garden with the atmosphere of a tropical jungle deep in the woods. The castle is a short bus journey or drive from Cork City and one of Ireland's most iconic landmarks.

If you don't have the time to visit the larger (but much farther) Litchfield or Kakadu National Parks, Charles Darwin National Park is a convenient alternative. Located a short distance from the city centre, just south of the airport, the area is one of the country's most important wetlands. It showcases 36 mangrove species and holds significant Aboriginal and historical importance.

With up to 45,000 yearly participants, the Chicago Marathon is among the global six World Marathon Majors.
