3 Best Sights in The West Side, Kauai

The longest stretch of beach in Hawaii starts in Kekaha and ends about 15 miles west at the start of Napali Coast. On the far west end is the 5-mile-long, 140-acre Polihale State Park, a remote beach accessed via a rough, rutted, potholed, 5-mile road at the end of Route 50 in Mana. (Four-wheel drive is recommended, and rental car companies may prohibit use of their vehicles here.) In addition to being long, this beach is 300 feet wide in places and backed by sand dunes 50 to 100 feet tall. Cultural sites, including burial sites, are located within the sensitive dune system. It is frequently very hot, with almost no shade and scorching sand. Start the day with a full tank of gas and a cooler filled with food and drink.  Though it's a popular beach, the ocean here has dangerous currents and is not recommended for recreation. No driving is allowed on the beach. The U.S. Navy's Pacific Missile Range Facility is adjacent, so access to the coastline in front of the base is monitored and restricted. The park is open for day use until sunset; permits are required for overnight camping. Amenities: parking (no fee); showers; toilets. Best for: solitude; sunset; walking.

Two restored camp houses, dating from the days when sugar was the main agricultural crop on the Islands, have been converted into a museum, visitor center, snack bar, and gift shop. About 3,100 acres of McBryde sugar land have become Hawaii's largest coffee plantation, with its 4 million trees producing more than half of the state's beans. You can walk among the trees; view old grinders and roasters; watch a video to learn how coffee is grown, harvested, and processed; sample various estate roasts; and check out the gift store.

The center offers free self-guided tours through a small coffee grove (about 20 minutes); a personalized one-hour "Coffee on the Brain" tour for $25; and a "seed-to-cup" farm tour in an open-air truck for $45. From Kalaheo, take Route 50 in the direction of Waimea Canyon (west) and veer left onto Route 540. It's 2½ miles from the Route 50 turnoff.

Carved over countless centuries by the Waimea River and the forces of wind and rain, Waimea Canyon is a dramatic gorge nicknamed the "Grand Canyon of the Pacific"—but not by Mark Twain, as many people mistakenly think. Hiking and hunting trails wind through the canyon, which is more than 3,600 feet deep, 1 mile wide, and about 14 miles long. The cliff sides have been sharply eroded, exposing swatches of colorful soil. The deep red, brown, and green hues are constantly changing in the sun, and frequent rainbows and waterfalls enhance the natural beauty. This is one of Kauai's prettiest spots, and it's worth stopping at both the Puu ka Pele and Puu Hinahina lookouts within the state park.

Public restrooms and parking are at most proper lookouts, and the main one has ramps for strollers and wheelchairs. If you stop at small pullouts, park completely off the highway and look for cyclists before opening car doors.
