Climate/Seasons. Throughout the year, temperatures seldom drop below 60°F. Summer weather (May to October) normally brings steady tradewinds and occasional showers while winter weather (October to May) is less predictable. Tradewind showers are more frequent during the night and early morning. Infrequent widespread storms cause flash floods.
Gear. Travel light. Lightweight hiking shoes with good traction are popular. Camping gear should include a lightweight sleeping bag or blanket, sleeping pad, tent or tarp, cooking stove and fuel, water purification tablets or filter, first aid kit, mosquito repellent, sunscreen, rain gear, and biodegradeable soap.

The hiking trail through the Na Pali Coast to Kalalau Valley is one of the most famous trails in all Hawaii, offering enchanting views, pristine beaches, and total seclusion. It’s also one of the most difficult trails, however. The round-trip trek to Kalalau Valley cannot be completed in one day and is recommended only for experienced hikers and campers.
You needn’t travel all the way to Kalalau to get a sampling of inner Na Pali’s beauty. It’s 21⁄2 miles to secluded Hanakapiai Beach. You can make this round-trip in one day; allow about four or five hours. But proceed with caution; parts of the trail are very narrow and slippery. This hike is not recommended for kids younger than ten and should probably be undertaken only in dry weather.
As an alternative to hiking into the interior of Na Pali, a slew of companies offer a different view—from the ocean or the air.
