A trip to Puerto Princesa Underground River is often paired with an adventure side trip. It could either be in Sabang X, the zipline by the sea made famous by Amazing Race Philippines Season 2, or in Ugong Rock Adventures, an ultimate destination for adrenaline rushing activities such as caving, spelunking and ziplining. My thrill-seeker husband yearned to visit both attractions, but since we were a part of a group tour, we only had to choose one and we picked out the latter.
Right after our buffet lunch in Sabang, we made our way to Ugong Rock Adventures before heading back to the city. Ugong Rock is a limestone rock formation which stands 75-feet high in the middle of a rice field. Within are caves and narrow passageways leading to a viewing deck situated at the top of the stunning rock formation. It was named as such because a hollow limestone inside the cave makes an ugong or a reverberating sound when tapped.
