No, you do not usually need to inform authorities for normal travel, but notification or permission may be required if you plan to enter restricted or sensitive zones.
Normal travel
Travel between cities and popular tourist destinations does not require prior notification. Visitors can move freely along standard routes.
When notification is required
Travel near border regions or into restricted areas may require permission or advance coordination with local authorities.
Role of checkpoints
Checkpoints often handle documentation and basic registration during travel, reducing the need for prior reporting in most cases.
Common misunderstanding
It is often assumed that all travel must be reported, but this only applies to specific sensitive locations.
