With its "majestic cliffs," "sparkling waterfalls" and "golden sunsets," Kauai is considered one of the world's most "spectacular" islands by Frommer's, perfect for both active travelers and those who just want to relax.Frommer's: Kauai Overview

1. Na Pali Coast: A "major must-see," hidden along its sea cliffs are numerous waterfalls, caves and beaches. Travelers can see most of the "gorgeous" coastline by helicopter, by hiking the Kalalau Trail or via boat.Fodor's: How to See Kauai's Na Pali Coast (September 6, 2007)
2. Beaches: Poipu Beach Park is a popular and "fun" beach on the island, but for those seeking less crowds, Fodor's suggests the long stretch of Polihale State Park.Fodor's: Poipu Beach ParkFodor's: Polihale State Park
3. More Beaches: Frommer's names Anini Beach County Park the "safest" and one of the "most beautiful" beaches. Its shallow waters make it the "very best snorkeling spot" on Kauai. Hanalei Beach Park is another "natural beauty" that offers "excellent" swimming all year long.Frommer's: The Best Kauai Beaches
4. Waimea Canyon: The "Grand Canyon of the Pacific" is 12 miles long and over 3,500 feet deep.Frommer's: Frommer's Favorite ExperiencesConcierge.com recommends driving or hiking the canyon in the morning for the "best views."Concierge.com: Waimea Canyon
5. Grove Farm Homestead: A "fascinating" and "authentic" dose of Hawaiian history, the museum is what Frommer's calls the state's "best remaining example of a sugar plantation homestead." Tours of the 19th century home showcase the "self-sufficient lifestyle" of its inhabitants, complete with "plantation artifacts" and "period furniture."Frommer's: Grove Farm Homestead MuseumFodor's: Grove Farm Homestead
