It's easy to go someplace, meet new people and immerse yourself in another culture. People you meet readily offer more information, assistance and even companionship to the solo traveler. Consequently, you learn more about the place you're visiting. And of course, you have total freedom to do just as you please every moment of your trip. Solo travel is a growing trend.
Safety is always the first concern.
Don't look like an obvious tourist. Dress conservatively and a bit more formally than you would at home. Avoid expensive or designer clothing, luggage and jewelry. Make a tentative itinerary and leave a copy with a relative or friend. Phone them periodically with updates.
