Went to Hawaii twice in 2006, took lots of photos. The Big Island and Maui are worth seeing, avoid Oahu at all costs.

Oahu

Waikiki (2/06) - Tourist trap to be avoided near Honolulu
Convention Center (2/06)- Where the AGU Oceanography conference was held for the week
Manoa Falls (2/06) - Short hike to escape the city
Polynesian Cultural Center (2/06) - A worthwhile tourist trap. Route to Laie took us by Lost and Gilligan's Island filming areas.
Diamond Head (2/06) - Horrible tourist trap for the hiking challenged - Did it for the views
Hanauma Bay (2/06) Snorkeling bay short bus ride away

Big Island

Volcano National Park (2/06) - BEST part of entire trip!
World Botanical Gardens (2/06) - A side trip to see the waterfalls and pretty plants
Windward side drive (2/06) - Post Volcano NP drive around the island
Leeward side drive (2/06) - Drive to view part of island not seen, near Hilo

Kona (10/06) - Base camp on the Big Island
Green Sand Beach (10/06) - Mission to find the Green Sand Beach (Olivine); harder than first imagined!
Punaluu Sea Turtles (10/06) - Viewing the Sea Turtles feed and rest
Saddle Road drive (10/06) - Drive to contemplate going to the top of Mauna Kea
Drive to northern part of island (10/06) - Checking out the non-tourist areas
Lapakahi State Historical Park (10/06) - Short side trip to a historic fishing villiage
Hapuna Bay Beach

Maui

Haleakala:

• Sunrise (10/26) - A photographers dream, the person standing next to them waiting - nightmare
• Sliding Sands Trail (10/26) - Trail into the crater. Deceptively long as the elevation gain is saved to the end of the day.

Drive around north-western part of island (10/06) - Check out surf and olivine pools, and travel narrow scary road
Iao Valley (10/06) - A beautiful valley and garden
