There are so many amazing places in the world but there are some that you will surely remember for a long time. Angkor Wat in Cambodia is just one of these places. You will surely know more about the culture of the country. There are also some structures that will not be seen anywhere else.
Venice in Italy is also one of the places that people should check although this has become congested with tourists through the years. Machu Picchu in Peru is so beautiful that it is enough to make people cry when they see it for the first time. The Great Barrier Reef is one of the best places to visit so you can enjoy.
Some places you should consider adding to your bucket list should include a good mix of countries and cities, as well as touristy destinations and those that are lesser known. A must see of South America is the country of Brazil. Of course, there are places like Sao Paulo and Rio de Janeiro, but there are also places that are a bit out of the way which allow you a more authentic experience and cheap, delicious food.
If you like the idea of Amsterdam, Ljubljana is its better and less-crowded sister. Again, much cheaper and not as touristy. A third country you absolutely need to see is Thailand. You have the ability to live and eat like a king, and experience the most vibrant, lush landscapes you've imagined. Simply beautiful.
