Several years ago I was blessed to chaperone an Eagle Eye week long retreat for high schoolers. Since then I have been a huge fan of the Community of St. John, and especially the ministry that they provide for young adults (teens, twenties and early thirties).
They combine a deep love of Jesus in the Eucharist with a celebration of life and the created world. Hiking, camping, adoration, prayer, games, Mass, philosophy and theology lessons, bonfires, praise and worship - all of it combines for an awesome opportunity.
I strongly encourage you to compare your schedule to theirs and see if you can attend one of their summer conferences.
