Is it possible to rent a kayak on a Sunday to go down the Wailua River? Are the beaches more crowded typically on the weekends, making it harder to snorkel? I am trying to work on my itinerary and welcome any advice!

Reserve the kayak in advance and you'll have no problems -- but the river is also home to water-skiers, so stay out of their well-marked area. And you'll be launching at the makai (ocean) end of the river -- so you'll actually be paddling _up_. Time your trek with the tides...makes it much, much easier. We like to paddle _up_ at slack tide (just as high tide is waning), then just drift back down the river as the tide is going out. Lazy kayaking, for sure! 8-)

Sunday is time for `ohana (family) throughout the islands...especially true at the beaches and parks here on Kaua`i. If you must snorkel on a Sunday, go _early_. That's also when the waters are at their most clear condition, so it's a generally good idea anyway.

This sounds like a great idea to me...Although I have no idea when the tides wane or going out. How do I find this out? Also, since there are five people in our party, I am thinking we can't have three kayaks fit on our car roof. Is there a company we can rent from that are located right there at the beginning of the river?

When you make your reservation, tell them you want to time your trip to all you to drift down with the outgoing tide -- the better kayak companies have the annual tide books and can handle that for you.

Many of the kayak companies will deliver the kayaks for you -- or rent from Smith's Boats/Kayaks since you want to do the Wailua River (they're located right there on the riverbank).

For snorkeling definately go to Kee beach but get there early as it gets crowded.Also check out Wailua Falls,Queens Bath,Spouting Horn,Waimea canyon,Secrets Beach.Kauai is a beautiful place..have fun!!!
