If you're looking for an exciting yet meaningful semester on your gap year, look no further. I have just returned from Pacific Discovery's trip to Australia and New Zealand, which was by far the highlight of my entire gap year. I originally liked this program for the adventure aspect, and saw the community service projects just as a little something extra but honestly, everything was a highlight looking back.
One thing I will say about this program, though, is that it is fast pace (which I like). This program is for the person who wants to get the most out of their time abroad, who doesn't mind waking up early to catch the sunrise (always worth it) or who doesn't mind leaving their comfort zone (Bungee Jumping, in my case). I am this type of person, and so it turns out that Pacific Discovery was one of the best parts of my life so far.
If you are the adventurous and active type, I couldn't recommend this program to you more.
