Triangle Park, near the intersection of Liberty Avenue and Fifth Avenue in front of Three PNC Plaza, opened in 2009, one of several newer small parks in the neighborhood. The Pittsburgh History & Landmarks tour emphasizes these new park spaces as well as the restored historical building and storefront that faces it, at top right.
Grjótagjá is a small cave that’s near Dimmuborgir. There’s a small parking lot just outside the cave. Climb down into the cave to witness the vivid blue waters. It used to be a popular bathing spot until the 1970s when there were volcanic eruptions. The temperature of the pool rose to 50°C (122°F), though it’s steadily declining.
