Called the "Gateway to Africa," what west African country is composed of tropical rainforest, oceanfront, and grassland?

The Portuguese arrived at the country's coast in the 16th century and were met with some fishermen. The fishermen said, "sunu gaal," which the Portuguese misinterpreted to be the name of the region. It actually meant, "These are our boats."
