The Kalalau trail that Jay is talking about is on the West coast of Kauai. The trail head is on the NW corner of the island at the end of the road. Yes, THE road. It is a lot more popular than it used to be, but the trail is still awesome. To go all the way out and back, it is really an overnight hike. You are supposed to get overnight permits but no one seems to get them. Actually if you hike past the 2 mile point (the first beach) you are supposed to have an overnight permit even if you are not staying overnight. Again, not too many people seem to get permits.
Some pix from the trail:

The trail can be fairly easy IF it is dry. That is a big IF. More than likely it will be wet. The red dirt in Hawaii is slippery when it is wet and muddy. I mean slippery. Like teflon has nothing on it. It will make the going very slow.
The center of Kauai is the wettest spot on the planet. Well, the wettest spot with a rain guage. Something crazy like over 400" of rain a year. Around the outside of the island it isnot that crazy, but you just need to expect showers to interupt your day every now and then. You dont need more than a light shell. If it is hot you might not even want to wear it. Put your camera in a zip lock bag or a dry bag though.
Waimea Canyon while only a few miles away as the crow flies is actually quite a long drive away. As the roads go, it is on the other side of the island. It is not like anything you will expect to see in Hawaii. It is the "grand canyon of the pacific".

I have an awesome shot of the view that enapai is talking about, but I can't find it.
If you do go out to Waimea Canyon, you might want to give yourself an extra day and then drive out to the end fo the road on the SW corner and go past the Navy's Pacific Missile Range Facility (PMRF). There is like a 6 mile dirt road that goes down to Polihale Beach. Bounce your rental car all the way down it to the beach. (don't tell them you did it though.) You can camp on the beach. Again, you are supposed to get a permit from the county, but no one does.
It is one of the most beautiful beaches in Hawaii. Most beaches in Hawaii are not this wide and there is NO sign of development.

IF you are there in March then most likely you will not be able to swim in the ocean. The N and W shores are very dangerous in winter. You need to be very careful even if it looks calm. The currents are very strong and huge waves can come up out of no where.
On Maui, you can drive up Haleakala and hike around the extinct volcano. It is cool, but Kauai is more diverse.

If you want to do crazy ridge hikes, then you need to go to Oahu and deal with the traffic. The hiking is very cool, but the traffic sucks. Oahu is not the "Hawaii" that you have in your head. Some parts are, but Honolulu is just a big city and there is a ton of people and terrible traffic. There are some awesome spots, but you need to know where to go. The ridge hiking is great though:

If you go to the Big Island and hike out to the lava flows, 1) be careful, 2) bring very good boots, and 3) be careful. There are a thousand and one ways to die by hiking out to the lava flows. I am not kidding. Go to the ranger station and tell them what you want to do and talk to them for advice on how not to die. I have hiked out to the lava flows at night before. I will not do it again.
There is other hiking on the Big Island that is not death defying. I haven't done much of it though. Sometime over the next year I hope to hop back over to the Big island to do some more.
