chamber music opportunities (for fun) for young adults?

hi guys, i'm in my early 20s looking for opportunities to play chamber music for fun around davis; it's been increasingly difficult to find dedicated programs that form groups (that aren't part of actual music degrees) since high school. or maybe i've just been out of the loop since stopping lessons..?

i have played the violin on and off for around 15 years so beginner summer programs would not appeal but i'm not trying to make this a career either; i'm not sure where to find something in between, like programs that have coaching and rotating assigned groups. does anyone here have any suggestions? thank you!
