Hiking

Maui offers some great hikes, and now you don't have to drive an hour to get to them. The Kapalua Resort has made some great hiking trails:
- Honolua Ridge trail
- old golf course trails
- nifty easy coastal trail
They are available to the public for free; they even offer a shuttle service to take you to a trailhead high up Honolua Ridge. You can then take a 7+ mile hike down the ridge through beautiful shady forests back to your car (less demanding options are available). There are also convenient, shorter (but strenuous!) hikes around an abandoned golf course, available without the need of catching a shuttle; and an nice coastal trail. You do need to sign a waiver and get an ID card before your first hike.

If you are willing to drive, there are many other great trails on Haleakala and above Wailuku.
