Quick answer
Wear quick-dry synthetic layers, closed-toe water shoes or sandals with grip, and bring a lightweight waterproof jacket or rain poncho. The cave interior holds 90 percent humidity and drops several degrees cooler than the outside temperature, while the paddle boat generates splash from bow waves. Avoid cotton t-shirts, flip-flops, and open-back sandals that retain moisture or slip on wet surfaces.
The Puerto Princesa Subterranean River National Park sees fewer wardrobe failures than most cave systems because the boat ride itself forces practical choices. Visitors who arrive in beachwear discover the gap between Sabang's open-air heat and the cavern's microclimate within the first hundred meters of the tunnel. The underground river tour demands two-layer thinking. Outer layers handle boat spray and the brief exposure walk from the wharf to the cave mouth; base layers manage the sustained humidity inside the eight-kilometer limestone passage. Synthetic fabrics wick moisture and dry within an hour after the tour ends. Cotton shirts soak through from both external spray and internal perspiration, staying damp through the return boat ride to Sabang and the van transfer back to Puerto Princesa proper. The cave's 24-degree interior temperature feels neutral at first contact, then uncomfortably cool against wet skin during the 45-minute paddle through the subterranean chamber. Footwear separates prepared visitors from those who spend the tour adjusting their grip. The paddle boat's fiberglass floor stays slick from constant moisture, and the entry dock at the cavern mouth runs wet from splash and condensation. Closed-toe sandals with ankle straps or amphibious water shoes provide the traction needed for boarding and the protection required if you need to steady yourself against the boat's low rail. Flip-flops and backless slides slip off during the step down from dock to boat, forcing awkward recoveries that disrupt the group's boarding sequence. A packable rain layer covers the gap most visitors underestimate. The boat generates its own weather through bow spray and paddle splash, concentrated in the forward seating positions where the guide's strokes throw water back across the first two rows. A hood helps if rain starts during the exposed walk from the Sabang wharf parking area, which happens without warning during Palawan's wet months. The same jacket packs small enough to fit in a dry bag for the return trip, when the sun reappears and the focus shifts back to heat management for the hour-long transfer to the city center.
