University of Rochester has several musical ensemble groups (including one specifically for jazz) for UR students only that are NOT open Eastman students. That jazz group is small (20 students) so auditions are competitive. (Depending on instrument played, competition can be intense.)
UR offers River campus students free music lessons with an Eastman grad student, but getting the lessons depends on an audition and instructor availability. For example, D was a jazz saxophonist and she auditioned for jazz sax lessons. She was ranked 4th out of 7 jazz sax students during her audition, but only the top 3 ranked students received free lessons due to instructor availability.
UR has an outdoor activity club and a ski club. D went canoeing in Canada with the outdoor group over a fall break one year. The ski club organizes 3-4 ski trips to local resorts every winter.
UR sponsors UR Foot-- 3 day overnight wilderness treks for incoming freshmen as part of the university’s freshman orientation.
UR is located on the Genesee River and a large city(county?) park immediately across the river offers canoe and kayak rental and ice skating in the winter. The Genesee River Trail begins on the UR campus, crosses the river on a dedicated foot bridge and offer walking/trekking and off road cycling opportunities.
