West Shore Oahu Beaches | Ko Olina

Can man-made Oahu beaches be any good? Absolutely! The Ko Olina Resort on the leeward (west) side of Oahu is home to four lagoons that are perfect for swimming and kids. My mom lives in the townhomes within the resort so we know these lagoons WELL and spend quite a bit of time here...maybe we will see you there one day!

The nice thing about man-made is that you can create ideal beach conditions. The lagoons are protected from the surf by large boulder walls but they made openings in the middle so the water does not get stagnant...notice I said openingS...they created three in each lagoon to allow the water to flow in through one opening and out the others...creating very nice conditions.

The four lagoons are numbered 1-4 and starts with 1 being the closest to the entrance. They are all basically the same with very minor differences. The number one lagoon fronts the JW Marriott Ihilani Resort and Spa and thus most of the people there are hotel guests. Below are pictures of Lagoon #1.

The number 2 and 3 lagoons are fronted by a couple time shares and Disney plans to open a resort there in 2011...the majority of people at these lagoons are guests of the respective adjacent properties. Below are pictures of Lagoon #2.

Lagoon #2 is my favorite one...there is a little cove on the right hand side of the beach that is separated from the rest of the beach by boulders...don't know why they made it but it is kind of a cool place to hang out...especially if you get there first.

Lagoon #2 also seems to have the best snorkeling within the lagoons...there are actually a fair amount of fish next to the rocks on the right side....just ask my eight year old! If you are more experienced, there is good snorkeling outside any of the lagoons.

Lagoon # 4 only has one property on one side and the Ko Olina boat harbor on the other. It also has the biggest parking lot by far...I would say about 50 stalls...Lagoons 1-3 only have about 15 stalls each. The majority of people here are either locals or visitors not staying in the resort area. On the weekdays, you will probably be able to find parking in any of the lagoons before 11:00 a.m. After 11:00 a.m. or on the weekends, lagoon #4 is usually the only one with parking available.

There are NO lifeguards here but there is an excellent beach front path that connects all the lagoons. This is also an awesome place to watch the sunset...there is live music at the timeshare at lagoon #3 and at the Ihilani (lagoon #1). You can hang out and enjoy your favorite beverage or just sit on the beach and listen to music while the sun sets over the ocean.
