One of the New 7 Wonders of Nature, the Underground River is Puerto Princesa’s crown jewel. A guided paddle boat takes you into a limestone cave filled with dramatic rock formations, bats, and an almost mystical silence.

Why DIY?
DIY booking through the tourism office or directly at Sabang costs about ₱1,600–1,800 compared to ₱2,500–3,000 for agency tours.

👉 The DIY price already covers:

• Environmental fee

• Audio guide fee

• Boat fee

• Pick-up & drop (van/bus to Sabang)

• Entrance fee

⚡ Plan it at least one day in advance since slots are limited.

Best time to go
Morning (8–10 AM) is ideal, cooler weather and smaller crowds.

Activity duration
The boat ride inside lasts ~45 mins, but with travel + registration, expect 3–4 hours in total.

What to wear & carry

• Light, breathable clothes

• Shorts + carry an extra T-shirt (humidity + splashes)

• Waterproof bag

• Reef-safe insect repellent

• Drinking water & light snacks
