There is no sunset here.
10 am to 2 pm best.
NOTICE: We have suspended service for Lanikai until further notice for a variety of reasons.
Lanikai Beach is a very popular 4 mile sandy beach on the Windward side of Oahu.
Unfortunately, it's almost always as busy most all times of the day, every day, with parking in the neighborhood side streets a big challenge.
The actual beach area is not that wide so you really don't want to have too large a group, we suggest no more than 10, the best would be just the 2 of you to fit between the people on the beach. Plan for 40 minutes of travel time from Waikiki depending upon the time of day.
If you really like the view and you don't mind the crowds i.e. people around you, behind you, and in your photos, up to you.
