Step into the fascinating world of cacti at Jardín de Cactus in Lanzarote, where more than a thousand different types of succulents from various desert and arid regions are on display. Situated in the village of Guatiza, the garden was the last project of renowned artist César Manrique, and his works can be seen throughout the garden. The garden is designed as a large amphitheatre, with terraced arrangements of plants that provide a stunning visual experience. A restored windmill, once used for producing gofio (a sort of Canarian flour), stands at the highest point, further adding to the charm of the place.

Dating back to 1072, the castle served as the primary residence of the Prince Bishops of Durham until 1832, when it transitioned into University College. Outside of term time, during student holidays, the building is open for guided tours.

A trip with a dog team, wrapped up in warm blankets under the northern lights, is a superb way of experiencing the countryside of Norrland. There's a good chance you’ll encounter an elk or a reindeer, too. There are four companies that offer dog sledding tours: Hedlunda Husky (www.hedlundahusky.se), Granö Beckasin (granobeckasin.com), River Lake Huskies (www.teamissa.se) and Aurora Borealis Adventures (auroraborealis.nu).
