Regions to know
To frame your trip by what you have time for and what you're after.
Northeast (NYC, Boston, DC)
New York City, Boston, Washington DC, Philadelphia, Niagara Falls
Dense, walkable, train-connected (Amtrak Boston-NYC-DC). The most European-feeling region. Best weather May–June and September–October; brutal humid summers, snowy winters. NYC + DC + Boston in 10 days is the classic East-Coast trip.
Southwest (Vegas, Grand Canyon, Sedona)
Las Vegas, Grand Canyon, Zion, Bryce, Antelope Canyon, Sedona, Monument Valley
Red rock + desert landscape = the most photographable region. Fly into Las Vegas (LAS), rent a car, do a 7–10-day national parks loop. Best March–May and September–November; brutal 45°C heat in summer at low elevations.
West Coast (California)
San Francisco, Yosemite, Big Sur, LA, San Diego, Napa
Pacific Coast Highway is the spine — drive SF to LA over 3 days. Yosemite 3 hours east of SF. Napa Valley 1hr north for wine. Year-round mild; cool foggy summer mornings in SF, hot dry in the LA area.
Pacific Northwest
Seattle, Portland, Mount Rainier, Olympic NP, Crater Lake
Rainy, green, mountains-and-coast. Seattle (Pike Place Market, Space Needle), Portland (food carts, breweries), Mount Rainier glaciers, Olympic rainforest. Best June–September; rain other 9 months. Coffee culture is the densest in the country.
South (New Orleans, Nashville)
New Orleans, Nashville, Memphis, Charleston, Savannah, Atlanta
Music + food + history. New Orleans for jazz and Creole; Nashville for country; Memphis for blues and barbecue; Charleston and Savannah for antebellum-era cobblestone old towns. Hot humid summers; perfect spring and fall.
Hawaii & Alaska (off-grid)
Maui, Oahu, Big Island, Kauai · Anchorage, Denali, Juneau
Detached from the mainland (5-hour flight from West Coast). Hawaii is tropical, year-round-warm, multi-island. Alaska is wild, glaciers + grizzlies + Denali, only viable May–September. Both are separate trips, not add-ons.
