Facebook is littered with them: your cousin's amazing trip to Europe, your sorority sister's trip to Guatemala. I've drooled over my laptop flipping through tropical hikes and European water ways, dreaming of all the places I have yet to go. Over time I compiled a list of all the trips I want to take, but there are a select few that I want to take before I turn 25. These are the true, blue, beautiful trips to take before becoming an official adult.

1. Rome

Rome is a classic stop on a European tour. You'll meet people in your hostel, travel with friends and have a great time exploring the eternal city. It truly is what dreams are made of.

2. Santorini

The classic white houses, turned toward the ocean make this the perfect setting for a vacation. However, right now, it may not be the best place to visit because of their shaky financial situation. This beautiful country will please the history buff, the artist and the writer.

3. Berlin

Berlin seems to be a city where the old meets the new. It was a city divided in political conflict that holds a large chunk of European history.

4. Istanbul

Between the Hagia Sophia, the beautiful panoramic views and the ocean laid out before you, who could want more?

5. Paris

One of the most visited European cities, Paris stands alone in its easy access to art, history and culture.

8. Hong Kong

Though polluted, this city holds an interesting cross between European and Chinese culture. It also holds some of the best shopping in Southern China.

The city on the Lagoon is another popular destination in Italy. To gently glide down the canals and wind your way through tiny streets and back alleys. You can discover new things around every corner and also street vendors.

10. Shanghai

This is one of the most high tech, modern Chinese cities well worth the trip.

11. Moscow

16. Ometepe Island

This Island, situated in the middle a massive fresh water lake is tropical and full of animals and wild life. This Island is very poor and there are many opportunities for community service.

19. Sydney
