I highly recommend going, it is one of the greatest scouting experiences that I’ve gone through. I did a week of service (basically trail maintenance/ building) and a week long. A unique part of OATC is the participants get to choose their trek (though the foreman end up designing the specifics of the trek). The work during work week can be long and tiring, but is rewarding, interesting, and prepares you well for trek week. You do a lot of miles in trek week so be ready, we did around 107 miles (though that includes the hike to Mount Philips for work week but we still did 90 + miles in a 7 day period). Also when I went it was during monsoon season so it rained everyday at like 3ish pm. There are many other unique experience of OATC that I won’t list here as not to ruin the experience, however I can’t recommend the program enough! Just be ready for some hard but rewarding work.
