The Palawan Museum is a small, old-fashioned museum near central Puerto Princesa with exhibits on the province's history, Indigenous cultures, archaeology, and natural heritage. The displays are not polished, but the collection is useful if you want context before heading deeper into Palawan.
It is best treated as a short rainy-day stop rather than a major sight. Pair it with the nearby Palawan Heritage Center for a fuller introduction to the island.
