Fort Siloso, the country’s only preserved fort and a military museum, is located on Sentosa Island. You can reach the fort via the Fort Siloso Skywalk trail, a massive steel bridge towering 11 stories up. Surrounded by lush tropical canopy, the bridge is accessed by either a glass elevator or simple stairs–though taking the elevator means sweeping open views of the Keppel Harbor, which you can’t really see if you choose to walk your way up. The 181-meter-long bridge offers great views of the nearby islands, as well as the jungle floor below.
Once at the fort, visitors can join guided tours to learn more about the history of the area–although it’s also possible to explore on your own, just walking around and seeing the sights.
Highlights inside the fort include the many massive cannons on display, three tunnel systems used to move ammunition around, and special exhibits showcasing daily life in the fort for the soldiers living there in the 1800s. The entire fort is a beautiful shaded park, where you can spend a couple of hours exploring.
