Despite its relatively small scale, this is a world-class attraction. It is the best-preserved Roman temple anywhere. Built in 19 B.C. by Roman emperor Marcus Vipsanius Agrippa, the original patron of the Pantheon in Rome.

A winding stone bridge links the mainland to this rocky islet, followed by 240 steps up to the small hermitage of San Juan de Gaztelugatxe. The chapel dates back to the 10th century, although it has been rebuilt multiple times following fires and pirate attacks. Even if the chapel is closed (which it often is), the climb is worth it for the stunning sea views, the cliffs carved into arches, and the remote, windswept feeling at the top - Game of Thrones fans will recognise the setting as Dragonstone. It’s about a 45-minute drive from Bilbao. You can also take a bus to Bermeo, a fishing town nearby, and continue by taxi or local bus. The trail is steep and uneven, so good shoes help.

The Royal Footsteps Along the Kona Coast Byway covers 700 years of history. The seven-mile stretch of road takes you through the centuries of Hawaii’s Alii, or the ruling class. You will be led past four of Kona's seven “Royal Centers,” which were the sacred locations chosen due to an abundance of natural resources and recreational value. These centers were reserved for the kings and queens of Hawaii. Count among them Hulihee Palace (one of three palaces in the United States), the royal surfing grounds of Kahaluu, Hawaii’s oldest Christian church and several heiau, or sites of sacred Hawaiian temples.
