If close encounters with reptiles excite you rather than induce fear, Agadir's Crocoparc is a definitive must-visit. Nile crocodiles are the stars of the show, but there are other reptilian inhabitants, such as snakes and iguanas. There's a free shuttle bus that runs to the park from the downtown.

Igidae Coastal Walk makes for a wonderful hike along the shore of the Sea of Japan. The path itself is of moderate difficulty, with some parts featuring pedestrian bridges and others running directly through natural terrain. The entire path is about 4km long and should take about 2 hours to complete in its entirety, but there are access points along the way which you can use to cut through to a nearby bus stop. The trail can be done both north to south and vice versa, although heading north is reportedly easier and comes with an added bonus of finishing the hike at the scenic Oryukdo Skywalk, standing on a see-through platform and looking down onto the rocky shore.

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.
