Having not done an extensive amount of travelling, my list is limited to the places I have been but each place is well worth a visit in my opinion:
1) Ngoro-Ngoro Crater, Tanzania.
Too much to take in in one day, going over the makes your heart jump into your throat, quite simply, the essence of beauty.
2) Thorong-La Pass, Annapurna Region, Nepal.
After a week of altitude sickness and a temperature of 104 F, words cannot describe the feeling of getting to the top, a great sense of achievement and being on top of the world - literally!
3) Rome, Italy.
Having been born there, I could be bias but just a few days there is enough to realise the power and greatness of this incredible city. You can spend the whole day just walking down little back-streets occasionally coming across a square or Piazza, snacking on THE BEST pizza in the world. When in Rome...
4) Zanzibar, E. Africa.
Untouched by throngs of tourists, just really laid back and beautiful - worth the choppy boat trip. Prison Island is a must, giant tortoises and a paradise beach.
5) Lushoto, Tanzania.
Beautiful little town in Northern Tanzania Usambura Mountains, go to the view point, only a few hours walk not too hard and the view is so worth the effort, Pride Rock in the Lion King was based on it! Very humbling.
6) Scotland, UK.
I went for the first time in January and am now hooked!
7)Dubai, UAE.
Only been for 3 days but just the most fascinating place, just a huge city in the middle of the desert! Dune driving is a mad rush and the heat! Just don't leave the hotel between 11am and 5pm, all the shops and businesses close then anyway and re-open till past 11.
Enjoy them if you find yourself passing!
