Rent a car.
Unfortunately, that is not an option
Unfortunately then you are going to pay a lot of money to get around in both places.
Outer island public transportation is not so good.
I start with www.hawaiiactivities.com
You can get ideas and prices there. You can book transfer from airport. Some of the tours will pick you up for free, others charge $30 a person.
We are actually doing both: using a car to explore some areas but paying for RTH and Haleakala tour bc I don’t feel comfortable driving those areas myself.
Care to share a few more details so people can help you better?
Any chance you’ll be coming from HNL? If so, it might be possible to change your flight to arrive at JHM which is in West Maui, very close to Ka’anapali. Then a quick Uber or Taxi ride would be easy and inexpensive.
At OGG, there are several shuttle companies that will take a group of people, making stops at several hotels. With only 1 or 2 people these can be most cost effective. I don’t know much about the various companies, but we do see Roberts and Speedie Shuttle recommended & also see complaints about the shuttles.
For 3 or 4 people, a taxi would be best. Uber was not available at the airport last I heard, except for their more expensive service. But I believe you can catch it just off site.
Hopefully someone with accurate figures will come along here, but I think you’re looking at somewhere in the range of $80.
Most of us do rent a car from the airport. Maui, and Kauai even more so, are difficult and expensive to see without a rental car. If there is any chance that it could become an option, it would be your best bet.
“Maui is a bad, bad place to be without a car.” lol, Scott, I think that’s a tad overly dramatic! ;-)
Melanie, we can help you get the most from your Maui time even without a car. It’s still a beautiful place to be. Ka’anapali does have its local shuttle. And if you happen to be staying at a Starwood property they have a shuttle that goes into Lahaina as well. Ka’anapali is a good place to stay without a car, if that’s the only choice.
We use Speedi Shuttle to get to our place near Kaanapali from the Kahului airport all the time. Cheapest way is a shared trip and book you return at the same time to receive a discount on the return. Once at your hotel you can use taxis, Kaanapali Shuttle, or even the public bus to go to and from Lahaina town for dinner, shopping and exploring. Some hotels, but not most, provide shuttles into Lahaina. Hope this helps.
It's totally survivable to do Maui without a car :-). And you can have a great time, too!
Do give us more info and we can help better. Teri's tip about flying into JHM is a very good one, if you can make that work.
