M.A.T. 25th Anniversary Celebration

In celebration of Mountain Adventure Tours’ 25th year of helping kids get outside every summer, Idaho BaseCamp is hosting a special weekend celebration at our Big Lost Campus, free for all to attend. Stay the night, or just come for the day — but bring the whole family and all your friends to connect with the community, enjoy great food and music, and learn what makes M.A.T. great. 

Whether you’re fly-fishing the Big Lost, building whimsical forts in the woods, exploring the area on bicycles, or relaxing in the hot tub under the summer stars, there’s something for everyone!


Thursday, August 4th – 6pm (doors open 5pm)
