Kauai Roads

[Max Rockatansky]

Looking for some suggestions on anything noteworthy road wise on Kauai that isn't State Highway or County Route.  I have a trip coming up the second week of November and current state highway inventory looks like a breeze:

Oscar's page doesn't really indicate anything interesting that wasn't a state or county route on Kauai:

FWIW, I will have a Jeep on this trip since it was for some reason the cheapest option. 


Edit:  Saving stuff like this in clockwise order so I don't forget about them later:

Old Hulemalu Road was interesting, I don't know if it was formerly an SR nor not, since nothing was posted. Had a few nice views...







There's no road all the way around the island, but I suppose you need a 4WD/high-clearance vehicle to get to the northwest quadrant of the island, which is rather quiet. I wanted to check out Polihale SP, but chickened out in my rental car, and kind of ran out of time; that path seemed to peel off from SR 50's west end at the Pacific Missile Base.

I mostly stuck to the the state routes and posted county routes, although I did tackle a few dirt ATV roads.

Polihale SP is my list as a "maybe."  It seems like that has to be a dry weather attempt and I'll have to check to see if it is off limits for rentals (the Big Island had a couple).

I was pretty much wiped out physically after hiking Waimea; wanted to explore more bridges but would up just doing 550 to the top (watch for massive potholes!) and 552 on the way down.

The dirt part of Lawai Beach Road looks doable with a Jeep, would probably have a beach nearly to yourself there.

FWIW, I will have a Jeep on this trip since it was for some reason the cheapest option. 

I rented a Jeep last time I was there. It wasn't 4x4, and had the same crap OEM tires that I had on my 2006 Nissan Titan pickup (I replaced the tires after a slippery drive on an icy road in Arkansas).

You might check out a foot trail into the Alakai Swamp, which follows a proposed road to connect what is now HI 550 with HI 560. http://www.hawaiihighways.com/FAQs-page6.htm#Kauai-gap I've heard the trail might pass by remnants of the construction equipment stuck in the swamp after a futile attempt to build that road.

One nice thing I've heard about that swamp is that mosquitoes are not a problem. The swamp is at about 4000' altitude, too high for the mosquito breeds that infest Hawaii.
