Once a federal prison housing dangerous and notorious criminals, Alcatraz (The Rock) now welcomes tourists into the cell blocks once occupied by the likes of Al Capone, Machine Gun Kelley, and the Birdman of Alcatraz. Self-guided audio tours have dramatic narratives of Alcatraz’s grim history, including realistic sound effects one would hear in prison. Apart from the prison complex itself, Alcatraz Island essentially operates as a national park. You can spend a full day hiking, taking in the view from multiple observation points and appreciating the natural beauty.

All goes swimmingly at this indoor aqua park. Attractions range from a toddler pool for the youngest visitors to gravity and twister pools for the most adventurous. Seaweed baths are also available for those weary travellers looking to relax after a long day.

This Spanish fortress, with cannons trained on the sea to deter pirates and invaders, is more than striking medieval architecture. It is also the “Shrine of Freedom,” to Filipinos tortured and killed here during the Spanish and Japanese eras. It is now a park with a resident theatre company for traditional and modern plays.
