Last Chance to Register for Summer Programs! We have a few spots open for all ages: LEARN MORE

Imagine fulfilling your high school graduation requirements by paddling whitewater, bikepacking and backcountry skiing. Imagine studying sciences, natural history and humanities in the forests and farms of New England, along riverbanks, in the desert, along the US-Mexican Border, and in the mountains of Ecuador…

Grit, determination and physical strength are just a few of the many skills learned along the semester trail.

Kroka Expeditions’ Semester School received approval as a New Hampshire non-public school. This is an exciting step forward for our Semester Programs, and makes our Semesters more accessible to high school-aged students.

Now, Kroka can grant high school credit for Semester coursework (in addition to college credit) and can award high school diplomas for any semester students who have completed all necessary credits and coursework. Yes, you can now graduate from Kroka!

Hand craft and Earth skills, including knife hafting and sheath making, are an essential part of the semester.

In addition, Kroka can now accept Vermont educational school choice tuition vouchers! (Maine students might be eligible, as well!) If a student from Vermont lives in a town with school choice they can use that tuition voucher to attend a Kroka Semester. This is an incredible opportunity for students in Vermont!
