Smaller than São Tomé, Príncipe has a dramatic landscape of jutting volcanic mountains covered by virgin forest and ringed by clear-water beaches. The island boasts excellent snorkelling and fishing, and locals can provide boats or bikes, or guide you on pretty much any kind of tour you want; negotiate a price.
The island's capital is Santo António, which is about the size of a large European village. The town's architecture is similar to that of São Tomé town but more run-down.
The centre of action is the very upscale Bom Bom Island Resort, to the north of the island, which has brought improved infrastructure and some very well-off tourists.
