Here are four of the U. S.'s least crowded parks, plus what to see and do in them.Channel Islands National Park , CaliforniaTourists find many ways to explore this group of five wild islands off the coast of Santa Barbara. Beginner-friendly paddling trips let visitors take in abundant sea caves and wildlife, such as gray whales and sea lions. Strong currents (洋流) and shifting weather make going with a guide a smart move.Kenai Fjords National Park, AlaskaThis coast-meets-mountains reserve takes wildlife watching to the next level. Use the park's only maintained long path to the outlook over Harding Icefield for breathtaking views of this icy landscape. Along the way, keep an eye out for black bears, wolves and mountain goats. From a tour boat, look out for whales and dolphins among the waves and sea lions and seals on the beaches. Carlsbad Caverns National Park, New MexicoBrazilian free-tailed bats are a star attraction at this park. Each year, these bats make their way back from the winter grounds in Mexico to rest in the park's network of limestone (石灰岩) caves. August and September bring the best bat watching when the year's babies take to the skies with their parents. Around sunset, the bats leave the caves by the hundreds of thousands to eat insects.North Cascades National Park, WashingtonKnown as the "American Alps", this park holds more than 400 miles of paths that take hikers and horseback riders to wildflower fields, old-growth forests, glacier viewpoints and remote lakes. One standout is the Desolation Peak Trail, which leads to a mountaintop cabin where Jack Kerouac, a famous 20th-century American novelist, spent a summer. （1） Which national park recommends guided tours?
