2. Explore Your Hotel

Rain’s got you in a slump? Instead of moping around, explore your resort and take part in some group activities.

It may be your chance to learn how to play the ukulele or dance the hula. Maybe you could even roll up your sleeves and make some leis!

Or if that doesn’t tickle your fancy, take a dip in the pool – you’re bound to get wet anyway so you might as well embrace it.

3. Go on a Wild Ride

Even when the rain clouds roll in, there is still plenty to do in Kauai. Don’t let the wet weather dampen your spirit of adventure – why not hop aboard an ATV tour?

Zip past plantations and up to an active volcano as you go off-roading through the tropics!

Rain may bring a chill to the air, but with a tour guide full of enthusiasm guiding you, you can be sure that you’ll still feel the heat of Hawaii’s warm hospitality.
