Summer travel is not as limited as you think, provided you're willing to serve quarantine when you return home (although that may change soon for vaccinated residents).
Following the reopening of Phuket on July 1st under the 'Phuket Sandbox' scheme, Mauritius has announced it will welcome vaccinated international travellers from mid-July. The gradual reopening of the island nation was announced by its tourism bureau, with the first phase running from July 15 to September 30. During this period, vaccinated tourists must stay in a certified Covid-19 safe hotel for 14 days; they can enjoy the hotel facilities as well as visit the beach.
Travellers will be subject to a PCR test at the airport on their arrival, and depending on the length of stay, they will also be required to do tests on Day 7 and Day 14. If they test negative on Day 14, they are free to explore the rest of the country, which is known for its white-sand beaches, sparkling sapphire waters, and rugged mountains great for hiking.
