11 Countries Where Tourists Are No Longer Welcome

10. Sardinia, Italy (Specific Beaches): Coastal Capacity Limits

Italy's island of Sardinia has introduced a system of daily quotas and advance booking requirements for access to some of its most pristine and popular beaches, particularly in the stunning Cala Gonone area. Beaches like Cala Luna or Cala Mariolu now have limited entry numbers and require booking well in advance, sometimes with a fee. This is a direct response to overtourism and environmental degradation, aiming to preserve the delicate coastal ecosystems and ensure a higher quality visitor experience for those who do get access.
