July Book in the Woods

The Rhythm of the Rain by Grahame Backer-Smith

Come for a self-guided, half-mile walk and read a story as you go. Rain falls on a mountainside, then trickles into a stream, roars over waterfalls and into the ocean. But its journey isn’t over. Fabulous illustrations tell the story of Isaac’s jar of water as it journeys around the Earth. A perfect family nature adventure and a great way to get your kids into the outdoors.
