Had a great time. Kauai is Chillax city. Great beaches around the island. We stayed in Princeville. Beaches great but not a lot of restaurants or night life, which was fine with us. Very nostalgic area. What I would imagine Hawaii was like 50 years ago in this area with not much changed. Hanalei bay is huge and is good for swimming, surfing, boogied boarding and windsurfing. Waves normally not huge but can be. And, it is so big, it will vary depending on the location I. The same day. Driving is slowwwwwww so don’t be in a rush. Most places aren’t too far away. Princeville to waimea canyon was about 2 hours. There is no road on the northwest of the island along the coast. So, you need to drive in a big arc to go from the north to the west. Favorite beaches- Secrets (a hike from parking), lumihai ( very similar to secrets but parking right at the beach) and a great photo op down the the right where the water a carved a cutout in the rocks for a little gorge with sand. Quite stunning, and Hanalei. Be prepared for passing showers daily. 30 seconds of drops to 10 minutes. Hard rain usually at night. If you want to get away from it all, come to Kauai
