Plaza Cuartel

At over 8 km in length, it is claimed to be the longest underground river in the world. With its crystalline waters and spectacular cave formations, the Underground River is possibly Puerto Princesa's most popular attraction. The site was also declared a UNESCO World Heritage site in 1999. The winding path of the river is navigable via small pumpboats that depart from Sabang Beach. Travel time from the city proper to Sabang is about 1.5 hours (This can take closer to 3.5 if you choose to ride in a Jeepney, since you have to wait while they deliver goods along the journey.) A permit is now necessary to visit the underground river and only available in Puerto Princesa, though an online system is in construction. As of 2018, you can purchase the tickets in Sabang pier: if you do it yourself it will cost you around ₱600, if you do it through your accommodation they might overcharge you up to ₱1200. You can also ask if you can make the return trip trekking the park and the jungle: you will need to get a guide to do that but the experience is worth your time and money.

Consisting of several islets with beautiful beaches, Honda Bay is the place to go to for swimming, snorkeling as well as beach and island hopping. Accessible via the Sta. Lourdes wharf which is 25 minutes away from the city. Pumpboats at the wharf can be hired to take visitors to the various islets on the bay. Arrive before 11AM to go island hopping if you require a small boat (1-5 people) and before 2:30PM if you require a larger boat.

A good example of a true correctional institute, the Iwahig Penal Colony is more of a farming community rather than a prison. Inmates often live with their families and are allowed to toil their farms to earn a living. Carving out handicrafts is also a common preoccupation and mahogany handcarvings are a good buy for tourists. The colony is about 35 minutes from the city center.

Formerly the Crocodile Farming Institute, and still referred to by locals as the "Crocodile Farm," is a tourist attraction and a national research institute devoted to crocodiles. About 30 to 40 minutes from the city center, the Croc Farm also has a mini-zoo, which features some of Palawan's endemic species of wildlife. The place is open from about 8:30AM to about 4:30PM. From Rizal Avenue you can take an 8-person covered pickup truck (labeled "Irawan") for ₱20 and the Croc Farm is the last stop; a tricycle carrying only one or two people will cost ₱100-150. Croc Farm Tickets cost ₱40 for adults and ₱20 for kids. You start with a guided tour of the crocs which last about 15 minutes. After that you wonder around by yourself in the endemic species area, where you have to be careful not to fall through a few rotton and crumbling wooden bridges. Although this is not the best managed wildlife area, the endemic species are nonetheless worth seeing and deserve your support.

With native Palawan butterflies is about half-way to the Croc Farm (above) and along the same road. Open 7 days a week from 8AM to 5PM. Entry is ₱50.

A very beautiful church that is decorated in blue and white.
