Charles River Aquatics runs a swim-focused summer camp at the Boston Sports Institute in Wellesley, where campers take multiple instructional group lessons each day across a warm teaching pool and a 25-yard competition pool, plus daily free swim, games, crafts and activities outdoors under tents. Full-day camp runs 9:00am to 3:00pm Monday through Friday, with AM and PM half-day options, as open-enrollment weekly sessions from mid-June through late August. It accepts swimmers ages 4 to 14 at any level, from true beginner to seasoned athlete, evaluating and grouping campers by ability at the start of each week. Each week carries a theme, and the camp is licensed by the Wellesley Health Department under Massachusetts DPH regulations.

★★★★★Brandy BlakelyCharles River Aquatics is a great swim school. My two daughters have taken lessons there the past 2 years and it's a very thorough and rigorous program. Both of my children are confident and safe in the water. My oldest child has now joined the swim team and she loves it! She has improved her technique, made friends, and found a love of swimming.
★★★★★Alexandra TaiebThe best to improve!!!! All the coaches are fantastic and welcoming. My 2 daughters swim for CRA and they still say it was the best time!!
★★★★★Timmy HoMy five year old son has been attending swim lessons at Charles River Aquatics for the last couple years. He loves it! Small class sizes, just three people in his lane with one teacher. During COVID, the instructors remained on the deck, but we strongly prefer the current set up with instructors in the pool. He is very comfortable in the water, and we're thankful for all of the excellent instruction. There is a family changing room and showers which he loves so he's not so cold after coming out of the very warm training pool.
★★★★★Lacey VerHageBest swim programs in New England! Both of my kids have taken swim lessons with CRA and my son has swum on their competitive swim team for 4 years. We tried tons of different swim lessons and programs in the area and found them to teach incorrectly and waste tons of time. Our son is an amazing swimmer thanks to CRA and our daughter is well on her way to being water safe and learning correct technique. All of the coaches and instructors are fantastic but most of all they have real swimmers in charge that oversee the programs well and pay attention to the individual kids. On top of it all, they have the nicest facilities around!
★Elisa PerryHad my son here for 3 months. Not a good experience. When I originally had him evaluated, they told me he just needed to work on a straighter kick and pointed toes. We swim regularly, and I noticed that after 2 months of lessons, there was zero improvement. If anything, his kick had gotten significantly worse. And he had started coming out of streamline positions to doggy paddle. Observing this, I checked in with the instructor, and the evaluator told me that he was doing a hybrid breast/freestyle kick with very bent legs. (Which he had not been doing previously). When I asked my son (he is 9 years old) about what he did in his lessons, he told me that they had him and another kid just kicking and racing across the pool, with little instruction. Thankfully, last week was parent observation. I watched as for the entire first 20 minutes, as he did 4 laps kicking (incorrectly) with a barbell, breathing forward. He received zero feedback or encouragement from the instructor. We pulled him out of lessons that day. $450 to be a worse swimmer!!!! What a rip-off!!! This was such a disappointing experience for us, since I have older children and we had a really great experience with CRA lessons 8 years ago. My older son still credits his good swimming ability to the lessons he took. Sad that they have deteriorated so much!
