1) New Year's on Copacabana beach- I will never stop talking about those fireworks (link coming soon)
2) Samba schools - in particular Mangueira- EU SOU MANGUEIRA
3) Hiking and waterfalls in Parque Nacional da Tijuca This park is the world's biggest national park in a metropolis and provides the most amazing views over the city of Rio! You're guarenteed to see animals you've never seen and if you get lost, you have plenty of jaca fruits to feed off of. Swimming after hiking over massive trees and using metal chains to get on top of big rocks gives it's share of adventure as well.
4) Ipanema beach - volleyball, sunsets, posto 9 Amazing sunsets, beautiful people, and huge waves!
5) Paraty boat trips and snorkeling I swam with turtles in turqoise water!!
6) Copacabana beach - late night caipinrinhas and the most ethereal sunrise after lapa It might be the caipinrinhas but the sunrise was heavenlike!
7) Sucos - my favorites abacaxi and hortela, carambola, laranga e acerola I'm opening a suceria in NYC!!
8) Hiking in Ilha Grande Beautiful island, amazing trails leading to stunning beaches!
9) Mototaxi to the top of Rocinha Yes, I almost got killed by oncoming vehicles but the views and the experience was worth it!
10) Prainha Surfer paradise
Honorable mention: drunken combi rides and rollercoaster buses!
