Achiefest is a weekend fellowship for the youth members of Achewon Nimat Lodge. Achiefest is designed to be a fun weekend where Arrowmen play games, have competitions and get ready for the section conclave. Achiefest, which was previously called the “Mikemosin” from the 1970’s through the 1990’s, is normally held at Camp Royaneh in March. However, on occasion, it has also been held as a one day adventure at various family fun zones like Boomers! in Livermore.
