The main square, or Plein, of The Hague is a great place to start upon arrival in the city as it is the focal point of the city and acts as a conduit for many prominent bars, restaurants, historical buildings and active government institutions. The square will be buzzing with life more often than not and sometimes key political figures as well as celebrities can be seen wandering about.

A 20-minute boat ride from Cancún lies the small island of Isla Mujeres with its laid-back Caribbean ambiance, tiny streets lined with stalls, and street cafés in pastel-colored houses. Golf carts and mopeds dominate the streets, and although the island is only 5 miles long and half a mile wide, it still offers plenty of things to do and see. Everything from a beautiful palm-fringed white beach on the north coast to a dramatic rocky shoreline on the eastern side to a sea turtle sanctuary and the remains of a Mayan temple at the southern tip. If you're into adventure, then you should visit the Garrafon Reef Park & Beach Club, where you can go zip-lining, snorkeling, and kayaking. Lastly, a must-visit for nature and wildlife lovers is a tour to Isla Contoy, a nature reserve only inhabited by a few biologists and restricted to 200 visitors per day.

Chillida-Leku is an open-air museum near the city of Hernani, about an hour and a half from Bilbao, dedicated to the Basque sculptor Eduardo Chillida. Around 40 of his monumental steel and granite works are dotted through meadows and woodland, with smaller pieces displayed inside the restored 16th-century Zabalaga farmhouse. The grounds are peaceful and easy to wander, and there’s also an organic café and shop on site.
