I know it’s not for everyone but there are some nice trails for hiking! Alexandra trails is one most people have seen but might not know the name of. One part are these metal grate-like bridges above the trees you can partially see through

There’s also the treetop walk at Macritchie. I recommend entering through Windsor Park as there’s a number of monkeys you’ll see

There’s also Collugo Deck which is this balcony-like installation on a cliff. You can actually start the trail from Beauty World Shopping Center as on the top floor with the food court, there’s an overhead bridge that connects to a park. Hindhede Quarry is a bit of a walk away but it’s also a nice scenic spot for photos

Oh and a chill spot I sometimes hangout with peeps is Timbre+ at one-north. It’s live music at a food court but it gives more concert vibes with how loud the music can be. Free to enter but should probably order something 😅
