Waimanalo Beach
This was the first beach we visited and certainly one of the most attractive (41-741 Kalanianaole Hwy Huli Street Waimanalo, HI 96795 a lot of the beach signage is hard to see, but if you find a beach parking lot in the town where the beach is located you can assume that is the correct beach). It was an extremely windy day, not uncommon with our experiences on the windward side of the island. The beach had gold sand and turquoise water, with mountain and island views. 
The sanded sitting area wasn’t too huge, but the beach looked pretty long to walk along if you wanted to find a quiet spot. There weren’t many other brave souls here on our windy day we visited. We didn’t go in the water or stay long, but I can imagine this is a gorgeous place to soak in the sun on a nice day.
Lanikai Beach
We got here early one morning and the place was quiet, but it soon packed up! There are many access points to this beach but I heard that 5 is a more low-key one, wonder what the others looked like (Mokulua Dr. & Kaiolena Dr Kailua, HI 96734)! The parking is in a nice residential neighborhood on the street; just make sure you read the signs to avoid tickets or towing. Similar to Waimanalo, golden sand and turquoise water, but there is more room to sit on this beach, and you get a different island view: The Mokes! 
The ones that you will see from the distance if you hike the Lanikai Pillbox Trail. The water was warm and wonderful, but the weather didn’t hold out too long for us to enjoy it. The windward side is wild! It started raining and was exceedingly windy. This is an amazing beach, just try to catch it on a nice day!
