OS Festival Vilnius in Vilnius
OS Festival is a free, family-oriented sport celebration at Vingis Park built around orienteering, run by the Lithuanian Orienteering Sport Federation. Around 25 activities fill the weekend, including the OS Labyrinth navigation puzzle, the OS Biathlon combining laser shooting with orienteering, and a rogaining race, timed to coincide with World Orienteering Week and aimed at introducing newcomers to the sport.
OS Festival is Lithuania's public-facing celebration of orienteering, staged over a weekend at Vingis Park and built to introduce a niche competitive sport to families and curious newcomers who have never picked up a compass and map.
