Hawaii vs Yellowstone and Grand Teton

Hawaii is the ultimate winter escape for Americans: no passport, no currency exchange and 80°F (27°C) days while the mainland shivers. Choosing an island is the first decision. Oahu is the energetic hub, with Waikiki's beach scene, the moving USS Arizona Memorial at Pearl Harbor, the Diamond Head crater hike and the North Shore, where winter swells send 30-foot waves rolling into Waimea Bay and the Banzai Pipeline. The Big Island is raw and vast, with active volcanoes at Hawaii Volcanoes National Park, night snorkeling with giant manta rays off Kona and stargazing near the summit of Mauna Kea. Maui, with the Road to Hana and Haleakala sunrise, is the romantic middle ground and deserves its own trip. This 7-day plan pairs 3 nights on Oahu with 4 nights on the Big Island, linked by a short inter-island flight of about 45 minutes. Book the key reservations early: Pearl Harbor's USS Arizona Memorial program, Diamond Head entry for non-residents, and a manta ray tour. Pack a light jacket for volcano evenings, mineral reef-safe sunscreen for the reefs, and plenty of patience for traffic in Honolulu.

Yellowstone and Grand Teton sit side by side in northwest Wyoming, linked by a short parkway, and together they make one of the great American road trips. Yellowstone, the world's first national park, holds more than half the planet's active geysers, including Old Faithful, plus the rainbow-colored Grand Prismatic Spring, the thundering Lower Falls of the Grand Canyon of the Yellowstone and terraced hot springs at Mammoth. It is also the best place in the Lower 48 to see big wildlife: bison herds in Hayden and Lamar valleys, elk, pronghorn, bears and, with patience and a spotting scope, wolves. Just south, Grand Teton's jagged peaks rise straight out of the valley floor above Jackson Lake and Jenny Lake, with sunsets that rival anything in the West. Fly into Jackson Hole or Bozeman, rent a car and plan on long but rewarding drives. Neither park uses timed entry, but in-park lodging books up months ahead, parking at Old Faithful and Grand Prismatic fills by late morning, and most of Yellowstone's roads close to cars from early November to late April, so summer and early fall are the main seasons.
