Hallgrímskirkja is an iconic part of Reykjavík's skyline and at 74.5 metres tall it is one of the tallest structures in the country. The gigantic church on the hill was a controversial project, but Icelanders have come to embrace their monumental tower in all its brutalist glory. The concrete mountain which took over 40 years to construct was inspired by the unusual columnar basalt formations along Iceland’s coast. You can admire the building inside and outside, go to the top of the tower to catch the view or attend an organ concert. The church is named after Hallgrímur Pétursson — a 17th-century minister and poet who wrote the “The Passion Hymns”. The book remains popular to this day.

Soak up the sun, swim, and snorkel in the turquoise waters of the Aegean Sea. Tours normally last either a half or full day, and include visits to nearby islands, stops for snorkelling and swimming, and even lunch or dinner on board.

Step into the Edinburgh Dungeon and experience 500 years of Scotland’s most haunting history. Be captivated by the performances of theatrical actors, mesmerising storytelling, and cool special effects that bring the scenes and stages to life. The bravest ones can also hop on one of the two scary rides. Guided tours depart every 10 minutes.

Jjimjilbang culture holds firmly in Korea, with the Busan area alone boasting around 450 spa centres (the largest number compared to any other region). It's important to note that the absolute majority of spas require that guests of both genders remove all of their clothing prior to accessing any of the baths or hot springs (this includes swimwear). Heosimcheong Spa is the largest of kind in Asia (and extremely reasonably priced), but there are other options for a slightly more refined experience that's still very affordable (the luxurious Spa Land Centum City, to name one). Some spas (such as Hill Spa, for example) remain open 24/7; these are sometimes used as a place to spend the night in lieu of a hotel room. For a lighter version of the experience, visit a "foot-only" spa, where anyone can sit down and soak their feet in hot thermal water for a few minutes. Dongnae Spa Outdoor Foot Bath is one address to experience this.
