April is broadly considered the best month for the Kalalau Trail — dry enough from winter rain, cool enough from summer heat, and not yet at the peak crowding of summer. The north shore has calmed significantly. Hanalei Bay is open for water activities. The vegetation is lush and waterfalls run at near-peak flow. The Milky Way season is beginning.

Magic window: Kalalau Trail Spring Window (Apr – May)

Trail conditions on the Kalalau are best in spring before summer heat and after winter rains have passed. The stream crossings are manageable, the vegetation is lush, and permit competition is slightly lower than summer peak. The valley is green and the waterfalls run at near-full flow.

Conditions

Weather: 80°F high / 67°F low. Ideal hiking conditions. North shore calm. Summer visitors not yet arrived.
