Also, do you have any idea the general weather for that time of the year for hiking the trail? Yes - you should always attempt to get permits for camping.
The State DLNR does not make it easy, but at least you'll have a good story when the rangers check.
Hiking on Kauai any time of year is pretty much the same in terms of temperature. Light shorts and top that can get wet then dry multiple times during the day are the best.
The key is to be aware and prepare for the conditions you might encounter. For camping / night long pants and some kind of hoodie are nice.
Extreme inclines and declines throughout entire 11 miles. Loose rocks underfoot and from eroding cliffs above. I highly recommend going the entire distance in one day because the camping is MUCH better at Kalalalu.
If you are afraid of heights and ledges you are not going to like miles 6.5 to 8! I've only hiked the first two miles in to Hanakapi'ai Beach and back and it was a fantastic hike! About 13.5 tough miles if you want to do a day hike (which I have and it's great).
My preferred stuff is Patagonia Capiline (other brands too) because it dries super quick and provides sun protection.
If I'm gonna hike back in one of the valleys I'll bring an ultra-lightweight shell that packs to softball-size.
I am cautious to say it's OK to harvest because this is a public forum and some might take offense.in Hawaiian - is one of the most beautiful and remote areas on Kaua‘i.The strenuous eleven-mile Kalalau Trail winds along this rugged coastline, providing the only land access to legendary Kalalau Valley.March can be very rainy or very sunny - hard to call.I'm planning to hike to Kalalau and camp for a night before returning the next day.The trail and facilities are rugged; some eroded areas are very narrow over cliffs that are hundreds of feet high.CAMPING PERMITS The Kalalau Trail is currently OPEN for hiking. Call the DLNR for more info: (808) 274-3444 Hawaii DLNR Main (info may not be current).I've written up some advice about this hike here: The most amazing hike i've done. Watch out during rains or for any sudden change in stream level. Is it possible to make it to Kalalau by nightfall if we start early in the morning? I noticed someone mentioned taking young children - is this advisable?I live on kauai, and a freind and I did this hike in and out in one day... I've seen many tourist (and locals) get stranded for a few days on the opposite sides of some of the rivers here (DO NOT TRY CROSSING IF YOU AT ALL DOUBT THE CONDITIONS) there have been many fatal accidents on this stretch of coastline. just bring enouph water and make sure you hit it during dry weather. I don't think I can make the entire 11-mile hike however, I would like to see Hanakoa falls. We're not planning to bring kids but the information on "narrow trails at great heights" and loose rocks makes me nervous.That said, there are many sources of food down the Na Pali. We are hoping to backpack the Kalalua trail in the middle of March, 2008.Do you know if you need a permit that time of the year?
