Napali Coast Trail
Koke'e and Waimea State Park
After two miles on the Pihea Trail is the junction with Alakai Swamp Trail. The scenery drastically changes from open valley to rainforest as you head into Alaka'i Swamp, the world's highest rainforest and swampland fed by the abundant precipitation on Wai'ale'ale's slopes. The trail is said to be the highlight of many visitors' journeys to the island, and it's one of our favorite hidden gems as well. As a bonus, in the last few years the trail has been greatly enhanced with boardwalks. No longer do hikers have to trudge through the mud to reach the magical lookout of Kilohana at the end of the journey.

Before you drive to the trailhead, check the trail and weather layer.
Hawaii hikes can change quickly with closures, rain, mud, heat, and daylight.
To help clarify this junction and the two trails, we've created three maps below: one is a Pihea Trail map alone, one a Alakai Swamp Trail map alone, and one that shows the preferred route that combines the two (from Pu`u o Kila at the end of Highway 550 to Kilohana lookout), here known as the Pihea and Alakai Junction Trail map.

Kokee and Waimea State Park
Don't forget to check our Koke'e State Park Hiking page for information on all the incredible trails inside the park. On that page we've also posted a map of the entire area (Koke'e and Waimea State Parks) for you to download and print out at home.
The Koke'e Lodge and Museum will also have maps available, but we'd definitely advise you to go ahead and review the map and become familiar with the area. The crisscrossing of trails and 4x4 roads can be confusing at first, but once you select your routes, it's not too bad. Feel free to contact us if you have specific questions.

Trades are breezy right now with scattered showers on the windward side and mountains; the leeward coast stays mostly dry. Tomorrow stays breezy with the same pattern.
A tropical disturbance southeast of the islands is likely to become a tropical storm by mid-week and approach the state Thursday through Saturday. The exact track is still uncertain. If it comes closer, expect heavier rain over a longer stretch; if it stays farther out, impacts will be shorter and lighter. Winds will increase late this week, with potential gusts over 70 miles per hour on the highest summits.
Plan your leeward beach time and snorkeling for today through Tuesday. Save summit drives and offshore water sports for after Saturday, and check updates daily as this develops.

Trade winds are pushing across Maui right now and staying breezy through tomorrow. Windward slopes and peaks will see scattered showers; the leeward side stays mostly dry. Rough seas mean a Small Craft Advisory is in effect through Tuesday evening.
A tropical disturbance southeast of the islands is likely to become a tropical storm by mid-week and approach the state Thursday through Saturday. The track remains uncertain. Late this week, winds will increase across Maui, with summit gusts potentially exceeding 70 mph on Haleakala. The Big Island—especially Hilo and Puna—faces the highest risk of heavy rain and flooding if the storm tracks close.
Leeward beaches and snorkeling work best today through Tuesday. Avoid summit hikes and offshore water sports Thursday through Saturday.
