150th Anniversary Travel trip to Australia in January 2027
Around the World with app: 150th Anniversary Tour

app celebrates its 150th anniversary during the 2025–2026 school year, and our travel program is joining the celebration by exploring 10 countries across six continents. Join the app Alumni Association and app Academy for Lifelong Learning (CALL) as we commemorate app’s global reach with an exciting line-up of tours.

Tour Status

This tour is being planned for some time in January 2027. Don DeGraaf ’82, app’s director of off-campus programs from 2009-2019, will be the tour host. 

We are announcing this tour extra-early as part of the six continents we’re visiting as part of our “Around the World with app” anniversary theme. Our CALL + Alumni Association travel planning committee will be developing this tour in 2025, with more details available in summer 2026.
