Can stand up paddle boards be rented after we arrive on the island or do they have to be reserved in advance.
Near Princeville, who is the best from which to rent.
They have their own dock right on the river, no fighting with the boards on your car. You can either go up the river or down a short ways and get out into the bay.
There are a couple of places that rent right at the Wailua river as well, another great place to SUP.
Another vote for Kayak Hanalei - I've used them a lot. The kayaks rent for 24 hours which means you can go out one day, bring the Kayak back and finish your rental the second day. Not sure if it's the same with the paddle boards. I took an SUP lesson with them which was excellent.
Thanks to all
