Instead of overwhelming yourself with the vastness of the USA, focus on one region such as New England, the South, or the Pacific Northwest.
Plan to spend at least 10 days to fully immerse yourself in a region. This allows time for exploring cities, national parks, and other attractions.
Avoid overplanning your days and leave room for unexpected delays or opportunities. Serendipity often leads to the best experiences.
Some popular hikes and activities in national parks require advance reservations. Check park websites well before your trip.
Like national parks, museums can also get crowded, especially during temporary exhibits. Make reservations for popular museums and attractions.
Mondays can be quieter for dining and exploring, especially in small towns or remote tourist areas.
Regardless of the season, pack layers for hikes as temperatures can vary, especially in mountainous regions. Don't forget sun protection and sturdy footwear.
In the USA, greetings are usually polite but not overly physical. Shake hands when meeting someone new and be punctual for appointments or meetings.
