Take hand-in-hand hikes into Waimea Canyon and Kokee State Park.

Soak up unparalleled natural beauty at several botanical gardens and sail along the towering Napali Coast.

Savor intimate dinners at romantic restaurants in Kauai’s finest resorts, and rejuvenate your mind, body and spirit at the island’s spas.

If you go to the Napali Coast to hike, leave early because parking is limited

In Princeville (North coast) the sunset should be awesome

Hanakapi‘ai Beach is dangerous for swimming

Always wear fins when snorkeling due to the extra power that they give the swimmer, and the possibility of currents in any surf zone.

Koa store sell original crafted souvenir

Tap water is good and drinkable (mmmm after the flood maybe is better bottle water)

We should not miss Sunset at Black Pot Pier

Kalalau Trail was closed for flood

Limahuli Garden and Preserve, and Lumahai Beach, were also closed due to the flood

Lydgate Park is filled with driftwood from the flood (should be clean now)

Stay away from stinging limu (seaweed)

People in Hawaii call a variety of marine organisms stinging limu, but only one true seaweed is known to commonly cause a rash in humans here. This blue-green seaweed, called Lyngbya majuscula (or sometimes Microcoleus lyngbyaceus) usually grows in clumps, looking like dark, matted masses of hair or felt. Most often this seaweed is blackish-green or olive-green, but it also grows in shades of gray, red or yellow.
