Nestled in the northern foothills of the Pyrenees, the Niaux Cave stands out as one of Europe's most remarkable Palaeolithic rock art galleries, featuring an array of awe-inspiring cave paintings. The cave extends over a vast expanse of two kilometres, comprising spacious galleries, low vaults, and underground lakes. The walls and ground of the cave bear a hundred or so animal representations and several hundred signs, showcasing the exceptional creativity and talent of our ancient ancestors.

Fort George was a colonial era fortification that was built in 1790s to protect the harbour. By the 20th century, the fort was no longer in use. Only a tall silk cotton tree growing within the fort was used as a lookout post to spot German submarines that patrolled the Caribbean waters. Today, very little remains of the structure. The ruins belong to the National Trust for the Cayman Islands and are an important remnant of the colonial times.

Portland is home to the nation's largest wooded urban park: a short hike in, and you'll barely believe civilization is only steps away. 70 miles of trails traverse the forest overlooking the Willamette River, and although you'll have nature all to yourself at times, you're sure to also run into Portlanders out on a jog or walking their pups — prepare to be greeted with a friendly "hello." If you have time, hike up to Pittock Mansion, a French Renaissance-style château that was once occupied by the family of publisher and businessman Henry Pittock, and has now been turned into a historic house museum open to visitors. Another popular hiking destination is the so-called 'Witch's Castle' (pictured) — remnants of an abandoned stone house overgrown with moss, used by local students as a Friday night hangout location. The place is steeped in a bit of mystery, and although there is no record of any ties to witchcraft, its original dweller is rumored to have been the first person in Oregon to be sentenced to execution for murder in 1859.

This intimate museum exhibits works which span centuries of Murcian art and culture. The carefully curated collection is free to visit and prides itself on its mix of both locally and internationally renowned art.
