We spent a hot day as a family floating down the river. All had fun from 8 year old, hard to please teenagers to adults. The river seemed very clean to us. Maybe the other reviewer expected a swimming pool. The scenery starting from Greenhouse park was amazing. For most of the trip you would never know you were in town. There was enough turbulence to keep it interesting. Staff were helpful and fun. Rickety bus ride up river added to the experience.
