Travel to Alaska's Inside Passage aligns with standard United States entry requirements.
For U.S. Citizens, no visa becomes necessary. For non-U.S. Citizens, specific requirements apply:
Ensure you carry these documents:
The United States Dollar (USD) serves as the currency. Credit cards are widely accepted throughout Alaska, especially in larger towns and on cruise ships. ATMs are available in all port towns for cash withdrawals. Currency exchange is available at major airports or banks, though these locations frequently present less favorable rates than your bank's ATM. A travel-friendly credit card without foreign transaction fees warrants consideration.
Standard U.S. Entry requirements pertain. Consult a medical professional for advice on routine vaccinations (e.g., MMR, DTP, Polio). They might suggest additional vaccinations like Hepatitis A & B, or Rabies if extensive outdoor activities or direct contact with wildlife are planned.
This frequently occurs on cruises or small boat excursions. Non-drowsy medications like Bonine chewable tablets or prescription options like Transderm Scop patches are considerations.
Sunscreen application with at least SPF 30 and wearing Sunglasses are advisable, even on cloudy days.
Mosquitoes and gnats might appear. Insect repellent application with DEET or picaridin, such as Sawyer Products MAXI-DEET 100% DEET Insect Repellent or Sawyer Products Picaridin Insect Repellent, is recommended. Consider treating clothing with Sawyer Products Permethrin Insect Repellent.
Wildlife Encounters:
Keep a safe distance from all wildlife. Never feed animals. Food storage should be proper when hiking or camping. For remote hiking, bear spray carriage and proper usage are advisable. LifeStraw offers water filtration products for outdoor adventures.
Hydration maintains wellness, specifically during active excursions or long days. Carry a reusable water bottle. Healthcare facilities exist in larger towns (Juneau, Ketchikan, Sitka); smaller towns possess clinics. Emergency services function via 911. Cruise ships commonly maintain medical facilities. Severe medical conditions could necessitate evacuation.
Tap water in all Alaskan towns and on cruise ships is potable. Food hygiene standards align with U.S. Regulations.
Crime rates in Alaskan port towns register as very low. Standard precautions against petty theft are prudent, especially in crowded tourist areas. No specific "no-go" neighborhoods for tourists exist.
Alaska is seismically active. While rare, tsunami warnings might occur; cruise ships and coastal towns have protocols in place.
These might occur in mountainous areas, especially during spring thaw or heavy rain. Following all local warnings and closures is advisable.
Hypothermia presents a risk in cold, wet weather without proper clothing. Dress in layers and wear waterproof outer shells.
Consider a well-stocked First aid kit, such as the Adventure Medical Kits Ultralight/Watertight .7 First Aid Kit. Keep Pacsafe anti-theft products in mind for securing valuables.
Bandages, antiseptic wipes, pain relievers, Anti-diarrhea medication, antihistamines.
Motion sickness medication, insect bite cream, blister treatment (Moleskin).
High SPF Sunscreen, Lip balm with SPF, sunglasses. Insect repellent (DEET or Picaridin).
