Our daily rate is $8 for 18 & up, $6 for 2-17, and free under 2. They offer a family rate of $60 per month, $230 for 4 months, or $600 annually.
Our public pools are part of the city rec center. The outdoor pool has a 1 foot deep area for little kids with several slides and climbing stuff, a lazy river, 2 large water slides, and a big "regular" pool. Inside, in addition to the gym-type stuff, there is a lap pool, another shallow pool with playground, a smaller lazy river, a smaller regular pool, and one big slide.
There is a pool the next town over that is smaller, but still has one big slide, a zero-entry area, and sprayers. It costs $2 for adults and $1.25 for kids. It also opens earlier (10 am vs. noon) We go there a lot because it's cheaper, has better hours, and it's easier to keep an eye on my kids in a smaller area.
