The Trust for the National Mall and its partners at the National Park Service invite you to be a part of the historic celebration of America's 250th anniversary and join our special expanded Volunteers-in-Parks (VIP) Volunteer Corps. In 2026, Volunteers will be the first line of welcome for the nearly 50 million people expected to visit Washington DC and the National Mall during this monumental year. Be a part of specialized trainings, engaging celebratory events, and a thriving, dynamic community of civic-minded individuals championing our public lands and shared American stories. Be a part of history for a year like no other on the National Mall. You’ll help visitors connect to history for America's 250th... and for generations to come. Volunteer at the Lincoln Memorial Undercroft. Volunteers at this site will work closely with rangers to help with ticket information, support visitors' ticketed-entry, and provide roving interpretation inside the exhibit spaces.
