There is no parking lot. The county recently widened several areas of road to accomodate some parking. These upper pull-offs offer a great view of the bays and of the Napili Coast and Molokai.
Parking is generally more abundant at the bottom of the ravine that feeds the bay.
There is now a railed stairway down to Mokule'ia making it much safer getting to that bay. The land you have to walk through is private property. It is so lush and cool that you seem transported back to old Hawaii. Please respect the rights of the people that allow you to cross their land to get to the best part of the bay, pack your trash away with you. There are no public bathrooms, showers, tables etc.
