The highest peak on the island of Madeira, Pico Ruivo can be reached only on foot, usually either from Pico do Arieiro (6 hours) or from Achada do Teixeira (2–3 hours). Listed as an "ultra-prominent peak", both trails are difficult. Be ready for steep ridges and slopes on this rewarding hike for the most experienced hikers.

Over a century old, the Speicherstadt is the world's largest integrated complex of warehouses. Visitors to Hamburg will discover a picturesque setting of Wilhelmine era Gothic architecture rendered in red brick, featuring unusual gables and towers. Precious commodities are stored at controlled temperatures behind the massive walls: coffee, tea, cocoa, spices, tobacco, and the world's largest collection of Oriental rugs. If you're pressed for time or wish to give your feet a rest after exploring the city, consider taking a one-hour evening boat tour. The Speicherstadt looks particularly enchanting at sunset.
