Hawaii vs Utah Mighty 5

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.

Utah's Mighty 5 is the classic Southwest road trip: five national parks strung across roughly 400 miles of red-rock desert, each completely different from the last. Start in Zion, where the Virgin River has carved a sheer sandstone canyon you explore by shuttle, then climb to Bryce Canyon's amphitheaters of orange hoodoos at more than 8,000 feet. Scenic Byway 12, one of the most beautiful drives in the country, carries you to Capitol Reef, a quieter park of cliffs, petroglyphs and pioneer orchards near the small town of Torrey. The trip ends in Moab, base for Arches and its 2,000-plus stone arches and for Canyonlands, where the Island in the Sky mesa looks down on the Colorado and Green rivers. Most travelers fly into Las Vegas or Salt Lake City, rent a car and spend about a week, sleeping in Springdale, Bryce or Tropic, Torrey and Moab. Plan ahead: Arches uses a timed-entry system in its busy season, Angels Landing needs a permit, and summer afternoons regularly top 100°F (38°C), so early starts, plenty of water and spring or fall dates make the biggest difference.
