About

Public facility for swimming laps, lessons and recreational swim teams.

The pool at Las Posas Park is heated, and public pools of this nature typically maintain a water temperature in the range of 80-82°F (26.7-27.8°C) to ensure comfort for recreational swimmers and those participating in aquatic programs.

What are people saying (AI review summary)? The facility is highly praised for its cleanliness, clear water, and well-maintained restrooms. It's considered excellent for families and children, offering a pool with fun water features and being suitable for lap swimmers. Staff and lifeguards are consistently described as friendly, helpful, and attentive, with special mention of patient and effective swim instructors for children's lessons. The park also serves the community well with areas for soccer, tennis, and general exercise, often with evening lighting. Entry fees are $4 per person per day, with annual passes available. Some tips include visiting weekdays between 10-12 to avoid large camp groups, bringing goggles (non-snorkeling), and bringing your own chair due to limited seating. One review noted the splash pad was under construction.

The park is very clean and well kept. It is used for soccer games Saturday most of the day during the season, and often during weekdays in the evening. It really serves the community well. The bathrooms are very clean and well kept as is the pool which has some fun water features for the children. It us also a great place for exercise and for tennis. If memory serves there is evening lighting till around 10.

Our family had a fantastic time at this pool on a hot, sunny day. It's perfect for kids to swim and relax. The clean, clear water and well-maintained restrooms made the experience even better. Upon entry, the friendly and helpful staff provided information about the fees: $4 per person per day, $90 per individual annual pass, $270 for a family of five for unlimited use. They also shared details about local swim teams our kids can join. We appreciate the excellent customer service and clean facility. Thank you for a wonderful experience.

It’s a nice size pool; I would just suggest for families to come to the pool between 10-12 during the weekday since camps of kids come and it gets absolutely crazy! They do have lifeguards that are on top of it but it’s easy to lose your kids in a sea of kids in a small pool. I would also bring goggles (just not the snorkeling type since it’s not allowed). There’s nice showers in the bathroom to wash off the chlorine. The splash pad is also not working and under construction. There’s not a whole lot of seating so bring a chair in case if it’s packed!

Nice Pool & Terrific Pool Instructors! My daughter began her swim lessons here at the age of 4. She has really progressed in her learn to swim class. The swim instructors are patient, and good with the varied little emerging personalities of the children. Also, there is always a lifeguard(s) on duty to keep watch on the other children while the instructor works one on one.
