Saba is the rare island in this region where a visit during July to September is actually pleasant (if there's not a hurricane) but a comfortably warm year-round temperature really makes Saba a good stop at any time. Prices are lower during the depths of their sunny winter (December to February), when most potential visitors (North Americans) tend to stay away from the tropics.
A strenuous climb up a virtual n_onstop_ run of stairs - 1064 in all - leads to Saba's highest point. As ample reward for the workout you get a close-up view of an elfin forest and a panorama of Saba and neighbouring islands when the clouds decide to part. Interpretive signs along the way describe the prolific flora and fauna.
