Here is a copy of the info I usually give regarding daytrips to Lana`i on the ferry:
<<A daytrip to Lana’i is a wonderful way to spend one day of your Hawai’i vacation. It is only a 10 minute walk from the ferry dock to Hulopo’e Beach, where you will find some of the best snorkeling in all the islands. You would need to bring rented snorkel gear along from Maui, as there is none available for rent on Lana'i. Here is a link to the ferry company’s website:
You will still be able to look for whales (in season) and dolphins from the ferry. From the left side of the beach as you face the water, you can also take a nice short hike up to Pu'u Pehe Overlook (Sweetheart Rock), where you will have great views of Maui and Kaho'olawe. There are also great tidal pools to check out around the beach. You can also take the 5 minute walk up to the Four Seasons Manele Bay Resort and check out the great artwork and beautiful gardens. Lunch at the Ocean Grill there has great views, although it is fairly expensive. Otherwise you can bring a picnic lunch and have it right on the beach. There are picnic tables, as well as facilities and showers there.
And if you are really interested in checking out the island, rent a Jeep from Adventure Lana'i Ecocentre and explore all the great isolated off-road sites. They will meet you right at the ferry dock with the Jeep, and you just leave it there at the end of the day. A Jeep is expensive, at least $129/day. For more info their website is:
But you will have to call them at 808-565-7373 to make a reservation.>>
