Kauai Itinerary: 4 Days on Hawaii's Garden Isle
Four days on Kauaʻi, organized to cover the south shore beaches, Waimea Canyon, the Nā Pali Coast by boat or trail, and the north shore's Hanalei Bay.
Kauaʻi rewards visitors who slow down. It is the most dramatically scenic of the main Hawaiian islands, and its best experiences, the canyon, the coast, the rainforests, are better experienced slowly than ticked off a list. This four-day itinerary covers all the major regions with enough time to actually be in each place rather than just passing through.
Day 1: South Shore
Fly into Lihue Airport and drive southwest to Pōʻipū. The south shore is the sunniest and driest part of Kauaʻi and the best base for the island. Check into accommodation and head straight to Pōʻipū Beach Park for the afternoon. The beach has calm water on the eastern end and more active surf on the west; the rocky point between them is one of the best places on the island to see Hawaiian monk seals and sea turtles hauled out on the rocks. Sunset from the beach is consistently good. Dinner in Pōʻipū or the nearby town of Koloa.
Day 2: Waimea Canyon and Kōkeʻe
Drive west to Waimea Canyon. The canyon is 14 miles long, 1 mile wide, and 3,600 feet deep: a series of red and brown layered cliffs cut by the Waimea River. The main lookout is at 3,400 feet; the Pu'u Hinahina lookout above it frames both the canyon and the ocean simultaneously. Continue up to Kōkeʻe State Park at 4,000 feet for the Kalalau Lookout, which gives the most dramatic aerial view of the Nā Pali coastline available by road. The temperature at Kōkeʻe is 10-15°F cooler than the coast; bring a layer. The Kōkeʻe Natural History Museum is small but provides useful context on the canyon's geology and native species. Return via Waimea town, which has good lunch options.
Day 3: Nā Pali Coast
The Nā Pali Coast is the defining landscape of Kauaʻi: 17 miles of fluted green sea cliffs, sea caves, and hidden valleys accessible only by sea or trail. You have two main options.
By boat: Catamaran and zodiac tours depart from Port Allen (south shore) in summer and from Hanalei in summer only. The summer sea conditions (April-October) allow full circumnavigation; winter tours typically do not reach the north Nā Pali. Book at least a week ahead. See our full Nā Pali Coast guide.
By trail: The Kalalau Trail begins at Keʻe Beach on the north shore (1.5 hours from Pōʻipū). The first 2 miles to Hanakāpīʻai Beach requires no permit and is one of the best day hikes in Hawaii. Go further (to Hanakoa or Kalalau) only with a camping permit from the DLNR. Keʻe Beach itself is excellent for snorkeling in calm summer conditions.
Day 4: North Shore
Drive the two-lane road north through Lihu'e and Kapa'a to the north shore. The Wailua River on the way north is the only navigable river in Hawaii; kayak tours to the Fern Grotto are a popular activity. Continue to Hanalei Bay, one of the most scenic bays in Hawaii: a crescent of sand backed by taro fields in the valley and Na Pali peaks in the distance. The town of Hanalei has good lunch spots and local shops. The road past Hanalei narrows dramatically to one-lane bridges and ends at Haʻena State Park, where the Kalalau Trail begins. Return south in the afternoon for your flight from Lihue. For more detail, see the Kauaʻi travel guide.

We research each guide against primary sources: the Hawaii Tourism Authority and Mālama Hawaii, the National Park Service, the State of Hawaii and its Division of State Parks, the National Weather Service, and the U.S. Census. For culture, language, and history we lean on the Office of Hawaiian Affairs, the Bishop Museum, and the scholarship of Mary Kawena Pukui. We send readers to those sources rather than speaking over them. When rules, prices, or conditions change, we update the page.
