About Cedar River Montessori
Located on 12 acres of forest, wetland, and pasture, Cedar River Montessori is proud to center anti-racist, anti-bias, accredited Montessori education for students from early childhood through middle school in south King County. Learn more about our mission and values here. Summer gives us a chance to explore both on campus and afield, all with daily swimming!

Swimming
We partner with British Swim School to offer a swim program designed to complement the Montessori philosophy your child experiences every day.
Swimming is more than a summer activity — it’s an essential life skill. Through consistent, structured lessons led by trained instructors, children develop water safety awareness, self-trust, and confidence that extends far beyond the pool.
Program highlights include:
- Small-group instruction led by expert instructors for all summer program participants at no extra cost
- Lessons that encourage routine and steady progress
- Guided water play that reinforces learning and exploration
- A focus on safety, confidence, and independence
Swim Lessons:
Early Childhood and Elementary students have daily group lessons or open swim time, conditions dependent. Lessons are 20-30 minutes based on the students' assessed swim levels and comfort in the water.
