Which experiences do you recommend?

Hello, my husband and I are visiting Maui in October and are starting to book everything. I have seen a bunch of interesting experiences I can book (snorkel to Molokini crater, zip lining, farm day experience, Lanai day trip, snorkel tours, etc etc) and was wondering which ones you have done that you would recommend? We are looking into booking one or two only so I want to pick good ones.

Some info: we are visiting for 10 days, want to be respectful to the natives and island, we are in our late 20s/early 30s, strong swimmers. If we do road to Hana the plan is to drive it ourselves
