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.

Painted blue by the sunlight reflecting off the water, the unique Blue Room Cave in northwestern Curaçao is a one-of-a-kind spot for swimming and underwater exploration. The best options to reach there are to take a boat trip or water cab, but it's also popular to hop in a canoe or hike from beaches like Playa Santu Pretu. As swimming is necessary to reach the cave, it is recommended to go with a guide.

The Funiculaire de Pau is a small railway running from Boulevard des Pyrenées to the railway station and mainly functions as a service for locals. The ride takes about 3 minutes and is perfect for children who will love this small train going up and down.

On the mountain of Doi Suthep, about 30 minutes from the city, you can find the spiritual temple Wat Phra Doi Suthep. This place is sacred to many people, hence very popular with both Thai people and tourists. Beware of the large amount of steps to get to the top of the temple, but once up, you can enjoy amazing views of the city.
