I love nature, and my favorite travels have been:
- México: Vulcanoes (Iztaccíhuatl/Popocatépetl), Tulum (Caribbean), Palenque, Bonampak (Chiapas), Real de Catorce (San Luis), Nayarit (San Panchito)
- US: Sequoia National Park, Yosemite, Great Canyon.
- Costa Rica (the whole country is amazing).
- Chile: Uinil de la sal
- Cuba (uuffff) Cuba is not about nature at all, but if you like music, you will be enchanted.
- Spain: Sevilla, Cádiz, Granada, Toledo, La Coruña, Santander, Donosti, all of them are beautiful (I love the most Andalucia, the southern region).
- England: I just have been in London, but I loved it.
- Poland: Zakopane, Potks, Krakov!!
- Holland: Amsterdam!!
- Belgium: Brujas!
- Portugal: I love Lisboa and a very closed town called Sintra with a beautiful beach.
- Indonesia: Yakkarta. Always visit the TigaLima Hostal, amazing place.
I can say many many many more.
