The MacRitchie Reservoir is Singapore’s oldest water reservoir. Its main purpose is to collect rainwater and provide drinkable water to Singapore’s residents. Additionally, the reservoir is the central feature in MacRitchie Reservoir Park. The MacRitchie Nature Trail is a series of boardwalks that vary in length and take you through the tropical rainforest. The TreeTop Walk — one of the park's main draws — is a suspension bridge that gives you a bird’s-eye view of the forest below. On your walk, you will definitely see some monkeys. They are definitely cute, but can be a little naughty, especially if you are carrying any food.

Six of the seven original Etruscan arches into the city can still be seen, with Roman, Medieval and Renaissance alterations. Take a walk around the city following the original walls – the tourist office in Piazza Matteotti has a leaflet with suggested routes.

Reflections from the moon stretch across the mud flats on very low tides creating the magnificent illusion of a long silver staircase. Tricky to photograph well, but breathtaking in person.

Channel your inner Tom Sawyer and visit these impressive rock formations inside the Arikok National Park. Between stalagmites hanging over your head and natural limestone columns, you will also catch a glimpse of cave art by the Arawak indigenous people, dating back to the first millennium BC. Visitors are only allowed to explore the entrance area, but the cave spreads for miles inside the rocks. A short guided tour is available.
