Some of Palawan's best attractions were never planned — they just happened. The Acacia Tunnel in Barangay Inagawan is one of them: a canopy of towering acacia trees arching over the South National Highway, forming a natural green tunnel that's become one of Puerto Princesa's most photographed landmarks.
How It Started
For years, this stretch of road had no name. It was just a scenic drive through Inagawan that locals took for granted. We first encountered it during a 2015 road trip along the South National Highway — the trees were already magnificent, but hardly anyone talked about them.
By 2017, the tunnel was gaining popularity on social media. But it also faced a serious threat: a road-widening project that would have required cutting down the trees. Over a thousand people signed petitions to save them, and the campaign succeeded. The acacia trees were preserved.
The Night Light Display
In March 2021, locals celebrated the tunnel's preservation with a stunning light installation — 4,000 light bulbs illuminating the acacia trees at night. It's become an alternative to the firefly watching tour, offering a different kind of magical evening experience.
Visiting Details
- Location: South of Puerto Princesa, approximately 1–1.5 hours from the city center
- Best times: Daytime for photography; evening for the light display
- Facilities: Parking spaces and food stalls available
- Tip: If you have a handheld drone, the aerial view of the tunnel is spectacular
Worth the Drive
The Acacia Tunnel is a reminder that Palawan's beauty extends well beyond its beaches and underground rivers. If you have a free afternoon — or want a unique evening outing — the drive south is worth it.
