(CNN) — Sometimes it feels like the best Mediterranean islands must've started taking this year's summer bookings back in the 1970s.
All the best spots are long gone, leaving just overpriced or underwhelming options for last-minute travelers.
There are, however, still a few Med destinations that are still so far under the radar that even at the height of the season there's a fair chance no one else will have found them.
These tiny, quiet and remote islands resemble the Med before its popularity went off the charts.
Here are 10 of the best:
Iles Sanguinaires (France)
Their name translates as the Bloody Islands, but while Iles Sanguinaires may have had a gruesome past, these days it refers to more relaxing qualities.
The uninhabited four islets off the western coast of the French island of Corsica are famous for their "flamboyant" purple sunsets.
The sea and sky appear to bleed, setting ablaze the reddish volcanic rocks and creating Corsica's best evening displays, according to locals.
They're a diving and snorkeling hotspot, not least because hundreds of ships crashed there.
Adding to the spooky appearance are ruins of a former quarantine station for coral fishermen with "sangrunero" (black blood) -- otherwise known as The Plague.
Mezzu Mare, the largest isle, has a lighthouse built on the remains of a Genoese lookout tower.
Getting there: Shuttle boats leave from the Corsican port of Ajaccio. Staying there: Stella di Mare on the Corsican mainland enjoys a superb view of the archipelago.

Reaching Linosa from Rome is a 24-hour journey -- but it's worth it.
This volcanic atoll is closer to the coast of Tunisia than it is to the Italian island of Sicily.
Landing here is like touching down on another planet -- Mars.
The jet-black beach of La Pozzolana has sulfur-yellow and red layers. Its Black Planet bar is popular for sunset aperitifs and private dinners.
Snorkelers dipping their mask into the water are greeted by black crystal-clear scenery.
The island is home to loggerhead turtles and there's a hospital dedicated to helping heal those hurt on fishermen's hooks.
At night, under starry skies, the turtles come ashore to lay their eggs.
A hike into the island's center reveals Monte Vulcano, an extinct volcano covered in fluorescent green prickly pears.
The island's main village is a bunch of low-rise pink and green dwellings.

Though it was once the scene of a bitter clash between Venetians and Saracens, this tiny island has largely existed in isolation.
Even today locals speak a dialect that most Croatians struggle to comprehend.
The stone-built streets of the old town are, like the rest of the island, car free -- only tractors, wheelbarrows and bicycles are allowed.

Visitors can cross it barefoot, but staying the night is prohibited -- camping and campfires are forbidden.
The atoll has one small tavern and a bar on Belegrina beach.
Belegrina, also known as "Golden beach," is covered in broken shells, coral and fossils that the Byzantines used to make a scarlet dye for coloring the cloaks of Europe's royalty.

Staying there: Cretan Villa Hotel overlooks the isle.
Spain's beautiful northeastern Costa Brava can get crowded with visitors in the summer, but these seven islands just off the fishing village of Estartit are a peaceful world away.
A marine park of 16,000 square meters, the islands host ruins of a wall built by the crusading Knights of the Holy Sepulcher.
Guided tours by biologists are held twice a year to the islands, which are a top snorkeling and diving site.
The reefs of Carall Bernatt and Tascons swarm with lobsters, giant groupers and even some bigger predators.

With no electricity and no engines, the only transport around this Italian island is donkey "taxi" -- and they're essential.
There are no paved streets, just 25 kilometers of mule tracks winding around the island and no fewer than 10,000 steps up and down layers of whitewashed dwellings.
Alicudi, the farthest and wildest of the Aeolian Islands, offers a no-frill, zero sound-pollution break amid turquoise waters and silent beaches.
Visitors should bring cash as there are no banks.
There's a tiny supermarket and news stand, but no other shops and nowhere to buy cigarettes, not that anyone should be smoking and tackling all those stairs.
