I am a 17 year old in my 6th year of learning Spanish, and would love to utilize my skills. Therefore I ask you: are there any opportunities you know of for a nice, Orthodox boy in any Spanish speaking country? I would like to be a counselor, but a camper would also work. I want something for Spanish-speakers, not something for tourists. I would like thrice daily davening and kosher food, of course.
Hm. My guess is you could try the various Chabad-Lubavitch installations in Latin America. You could go to godaven.com and search for Jabad. (Including one Spanish-speaking shul in Florida ... you learn something new every day!)
There's also this Or HaYeladim ("light of the children") synagogue north of Madrid; I suspect their administration would be able to tell you about summer camps in the area.
UPDATE: msh210 pointed out Chabad has a worldwide camp locator; looks like there's a few in Argentina for starters. That beats any of my ideas.
