What else?

Well, I try to travel a lot. Here is a history of some of my recent trips:



London is always worth a trip. Luckily we got some super cheap flights from Dortmund to London, so we made a short trip for one night into the capital of the UK. I really fell in love with all the parks in an autumn/winter style. A bit scary was the Winter Wonderland in the Hyde park, where the britain's tried to build a german "Weihnachtsmarkt".

Well, when we went to Copenhagen it was super windy and quite cold. But however the city has its own beauty and a lot of good street food. But if you want to take a few drinks and have some party, better bring enough money with you.

Nice trip to a very different country. We visited Matanzas, Havanna, Vinales, Cienfuegos, Trindidad and finally relaxed in Varadero. Cuba has its very own and slow flair and of course the best Mojitos.

Probably the most astonishing experience of my life. I travelled 3 weeks through the country with starting point in Bangkok. After the first cultural shock I moved to the north to Chiang Mai with a short stop in Sukothai. Second part of the trip included Krabi, Koh Phi Phi, Phuket, and Koh Tao. I really favorite the country, the nature and the people.
