Prepare for each country and route separately. Conditions and entry requirements vary, so use your government travel-advice service and destination authorities for current guidance.
Keep the essentials accessible
Save copies of your travel documents separately from the originals, keep important contacts available offline, and give a trusted person your itinerary. Check that insurance covers the activities you plan to book.
Make transport arrangements clear
Confirm who is collecting you, where you will meet and how to contact your accommodation if plans change. Allow time between unfamiliar transfers and use providers you can verify.
Revisit the plan before moving on
Check official advice, local conditions and border requirements before each new stage. Ask a qualified travel-health professional about health preparations relevant to your itinerary.
