Fort Siloso
Daily 10:00–18:00 (last entry 17:30) · MRT HarbourFront (NE1/CC29) + Sentosa Express
Famous for: A real WWII coastal fort with a skywalk
Guns, tunnels and a treetop skywalk at the tip of Sentosa. Free, and far better than it sounds.
💡 Ride the Skywalk lift up and walk down through the fort. Go after 4pm for cooler air; last entry 17:30.
