Kula, Maui

— 4 nights
Kula is a district of Maui, Hawaii, that stretches across the "up-country", the western-facing slopes of Haleakalā, from Makawao to Ulupalakua. Get out of town with these interesting Kula side-trips: Wailuku (Maui Ocean Center & Iao Valley), Lahaina (Lahaina Banyan Court, Ka'anapali Beach, &more) and Haleakala Crater (in Haleakala National Park). There's still lots to do: cruise along Hana Highway - Road to Hana, explore the landscape on two wheels at Bike Park Maui, and look for gifts at Proteas of Hawaii.

Side Trips

Volcano, Island of Hawaii

— 4 nights
Those who named Volcano opted for simplicity in choosing a title, taking the nearby fire-spewing Kilauea as a source of inspiration.
Explore Volcano's surroundings by going to Mauna Kea (in Kailua-Kona) and Hilo (Rainbow Falls, Akaka Falls State Park, &more). There's much more to do: trek along Kilauea Iki Trailhead, tour the pleasant surroundings at Devastation Trail, get outside with Keanakakoi Crater Overlook, and take in nature's colorful creations at Akatsuka Orchid Gardens.

To find photos, maps, where to stay, and tourist information, read Volcano online holiday planner.

You can fly from Kula to Volcano in 4.5 hours. December in Volcano sees daily highs of 80°F and lows of 65°F at night. Wrap up your sightseeing by early afternoon on the 29th (Sun) to allow time for travel to Honolulu.

The Aloha State
An archipelago of hundreds of volcanic islands located in a geological hot spot in the middle of Pacific, Hawaii offers diverse natural scenery and a warm tropical climate. The six major islands open to tourism draw visitors with their sun-drenched public beaches and craggy natural trails. Thanks to their mid-Pacific location, the islands boast a vibrant native culture influenced by both North America and Asia. You can spend your vacation basking in the modern comforts of the big hotels, but to experience the true spirit of these islands, remember that real Hawaiians live outdoors. Encounter nature by surfing, swimming, fishing, and picnicking, or join a guided tour across the ancient lava flows to the top of Hawaii's rugged volcanic peaks.
