Elmo and friends go hiking! As they walk in the woods, explore the edges of a stream and pond, sit in a meadow, they learn how to look and listen for clues to the creatures that live in these places. Along the way they also learn to take care of nature by staying on trails, not picking flowers, not feeding the animals. When Elmo, Grover, Zoe, Big Bird, Ernie, and Bert ask about what lives in the places they see, their trail guide gives clues to the answers. Readers can guess along with them and then lift the die-cut flap in each spread to reveal the creature and its name.
