We recently had the privilege of visiting Maumee's Rolf Park pool. My wife, kids, and I all agree that it's a great place to swim & play. It's great for all different ages, as well (I have 4, ages: 11, 4, 3 & 1). The older kids can use the water slides while the younger ones enjoy the "jungle gym" and different stations in the shallow waters. We swam & played for nearly 4 hours and we all had a blast. It's a little pricey, but, I believe, well worth the money (30 bucks for 5 of us). We plan on getting a season pass next year & save a little money. If you live in the Northwest Ohio area, have kids, and want a great, clean place to swim & have fun, I highly suggest visiting.
