New Orleans captivates with music, cuisine, and nightlife, but crime can spike in and around entertainment corridors. During Mardi Gras and other festivals, pickpockets and opportunistic theft increase. Stay in well-lit areas, avoid walking alone late at night, and keep cash minimal. Secure your phone and wallet in zipped pockets or anti-theft bags. Alcohol lowers vigilance, so designate a sober navigator. Research neighborhoods before wandering off Bourbon Street. Ride-hailing is safer after dark than long walks. Keep hotel doors locked and verify tour operators. With smart precautions, you can enjoy the culture without unnecessary risk.

7. Grand Canyon National Park – Arizona

Mount Rainier towers with glaciated slopes that conceal crevasses, unstable snow bridges, and avalanche terrain. Weather shifts quickly from sunny to whiteout, disorienting even experienced climbers. Volcanic risks exist, but the immediate hazards are falls, icefall, and hypothermia. Guided climbs, proper glacier gear, and crevasse rescue training are essential. Day hikers should check avalanche forecasts, carry layers, and know turnaround times. Streams swell rapidly during warm days. Navigation tools and radios increase safety on complex routes. Register itineraries, heed ranger advice, and do not underestimate early season snow on popular trails.

9. Glacier National Park – Montana

The Appalachian Trail spans 2,190 miles through varied terrain and weather. Hikers face black bears, dehydration, and hypothermia from cold rains even in summer. Crime is rare but not unheard of, so avoid camping alone near road crossings. Filter all water and carry a reliable communication device. Lightning on exposed balds can be severe; plan to drop below treeline during storms. Leave detailed itineraries with contacts. Respect shelter etiquette and trust your instincts about campsites. Seasonal heat waves also challenge endurance. Preparedness and flexibility are key for a safe thru-hike or section trek.

11. Detroit – Michigan
