One of the best things to do on Oahu is kayaking or paddle boarding to Mokulua islands.Moku Nui and Moku Iki.You can visit 1 island only but it is good enough.From Lanikai beach it would take you about 40 min to get there.You can see a lot of turtles on the way.You can also dive in any spot -there is a lot of coral reef under water.
