Get an advanced pass to Haena State Park as the Ke’e beach is beyond park parameters and you cannot access it without the pass. s
Set your calendar to get your pass exactly 30 days before your intended visit. Also note even though the home is really close to the park entrance, you still will likely need shuttle bus service to get inside because parking passes are very limited. Make sure you email the park a few days from the time you’re planning to go and let them know you want to get on the shuttle bus at Hā’ena Beach so you don’t have to back track to catch the shuttle.
With your car or our bikes you can easily drive to Haena Beach Park, Tunnel beach, or the end of the Kuhio Hwy road to the guard gate.
But, if you want to go to Haena State Park, the website to book a shuttle ride is https://gohaena dot com. It is a must for you to check it out.
Normally , everyone needs to drive back toward Hanalei ( it is too far to ride a bike there) at Waipa Park and Ride at 5-5631Kuhio Hwy. Park in the shuttle parking lot to catch the shuttle from the start, unless you email them proof of your reservation at our home 2 days prior. Then you could ride the bikes to the shuttlestop at Hanalei Colony Resort (to the east about 1 mile from house) or Haena Beach Park parking lot (to the west about 1 mile from house)
Also, unfortunatly, security is tight at the gate entrance to Haena state park. from sunrise to sunset. Unless you are are a resident, you can't get in during the day unless you are lucky enough to get a walk in pass on the https://gohaena website

As per website:
"Shuttle riders MUST check in at Waipā Park & Ride FIRST, then you can get on or off at any stop. Staying in Wainiha or Hā‘ena? Email us proof of accommodations address along with reservation WS# 2+ days prior for approval to board at a nearby stop"
