Completed in April 1998, the beautiful outdoor Trefethen Aquatic Center was made possible by a generous donation from a Mills College Trustee in memory of Eugene Trefethen, a long-time trustee and a strong supporter of intercollegiate athletic programs at Mills College.

Mills College and Middlebury students, faculty, staff, their immediate family, and up to one guest are allowed free access during our Adult Only Lap Swim and Recreational Swim times. The student, faculty or staff must accompany immediate family members and guests at all times in order for them to receive free access. Towel and locker rentals are free upon request. Goggles, swim caps, and padlock rentals are available for purchase at the front desk. To access the pool students, faculty, and staff will be asked to present a Mills ID (i.e. current student or employee ID, alumna/alumni card).
