In the summer of 2016, I took my first amazing EF trip: Ultimate Europe. It was a 35 day adventure around Europe. In the summer of 2017, I then went on a two week adventure to Japan and China, followed by three weeks in Australia and New Zealand. Throughout my three trips, I have had nothing but positive things to say about the company. EF (Education First) is a company that designs and organizes trips, and the College Break section specializes in trips for the 18-28. And no, you don't have to be in college to go.

A lovely company I have used to plan a couple trips.
Contiki
This is the tour company I went to South America with, and it was awesome. Since it's not a US company, you get a mix of people in your tour from a variety of places, which is super fun. The plan tours for ages 18-35.
