This entry describes how to tie together the various activities and sights I've described on the East and Northern coasts of Kauai - plus a few more. You can't actually circumnavigate Kauai by car, because the road ends west of Ke'e Beach on the north shore, and also at Barking Sands Beach on the west shore. However, if you don't linger too long in any one place, the East and North coasts can be combined into an afternoon or day trip, as can the South and West coasts. Without any stops, Lihue to Haena should take you about 90 minutes.
Begin in Lihue, where rental cars can be picked up at the airport. Breakfast at Dani's Restaurant in Lihue is an inexpensive look at how the locals eat, if you've got time. Take Highway 56 (also called Kuhio Highway) and head North out of town.
With only one day to spend on the island, I didn't have time to take a detour up route 583 to Wailua Falls, where you can paddle up the Wailua River (rent kayaks in Kapaa) and visit the tourist-infested Fern Grotto, then continue upriver for the short hike to Ho'olalae or "Secret" Falls.
Stop in Kapaa to pick up gear at Snorkel Bob's for your snorkeling or beach-going needs later in the day. Kapaa is also a good place to rent a kayak if you're planning on spending more time in the water. Kapaa itself isn't a particularly nice town, but it does offer plenty of services. For instance, if you skipped breakfast, or are hungry for lunch, you can find food in Kapaa (try the Aloha Diner or Pono Market for typical local cuisine and "plate lunch") but try to wait until you get to Kilauea.
North of Kapaa, the highway turns inland, but not before giving you a glimpse of the beautiful soaring peaks of the Anahola Mountains. A calm swimming beach may be found in Anahola (see "Coconut Coast beaches" entry), but if you're planning to go further or are a devotee of snorkeling, however, keep going. It gets better!
At the 23 mile marker, you'll reach wind-swept, stunning Kilauea. Make a right on Kolo Road, pausing to look to your right at the Christ Memorial Episcopal Church, made entirely of lava rock. Then bear left onto Kilauea Road to reach the Kong Lung Center, a vintage trading post cum tourist attraction, and the unforgettable Wildlife Refuge/Lighthouse.
If you're hungry now, lunch is waiting at Kilauea Bakery/Pau Hana Pizza but save some room for the mouth-watering treats at Banana Joe's - or at least plan to stop there on the way back!
Continuing West on the highway, you'll pass Princeville, an ultra-luxury resort overlooking the Hanalei bluffs. Next is the Halanei Valley Overlook, worth stopping at for a glimpse of a true Hawaiian vista. Terraced taro fields blend into wildlife refuges and wild stretches of untouched land. At the bottom of the hill is Hanalei Bridge, a one-lane rickety looking affair that is closed in foul weather lest flash floods trap unwary visitors west of their escape route. Happily, tour buses are too heavy to cross over it, so anything west of here is likely to be even more unspoiled than their eastern counterparts.
Hanalei is very tourist-friendly - but I prefer to think of it as (ahem) charming. The Hanalei Center and Ching Young village are colorful, fun-loving smorgasbords of shops, restaurants, and crafts. There are tons of places to eat, shop, and overnight here. Keep going though and check out the bay! Also on your radar should be Lumahai Beach, coming up right after you round the corner past Hanalei Bay. Keep going and the jungle will start to encroach upon the road. The asphalt narrows, small streams meander (when it's been raining) across the pavement, and somewhere past the 8 mile marker (the numbers reset after the bridge), you'll encounter the gaping mouth of Maniniholo Dry Cave on your left (and Haena Beach Park on your right). Maniniholo is an interesting excursion - better if you remembered to bring a flashlight. Vines are draped ominously over the entrance. Wild taro grows within, and water drips occasionally from the ceiling. Maniniholo is an enormous former lava tube. Walk as far as you dare toward the back as the ceiling lowers. If you brought that flashlight I mentioned, you can follow a passage at the back left wall a fair distance.
Your last stop before turning around should be Haena, where I strongly recommend leaving your car and proceeding to Tunnels Reef for some world class snorkeling. The road continues a bit further, and there are two caves - one wet and one dry - to explore. Go ahead if you have time, and let me know how they were!
A final note: Past Haena, hearty adventurers with time to spare will have just begun their trip. The Kalalau trail begins where the road ends, traversing 11 rugged miles of inland beauty and the untouched tops of the Na Pali coastal cliffs to Kalalau Beach. If I ever get back to Kauai, I'll make sure I'm in decent shape and have plenty of time for this, the ultimate Kauai adventure.
