Astrotourism Is Taking Off — and These Are the Best Places in Europe to See a Sky Full of Stars
Astro travel is having a moment. The way people vacation is shifting away from crowded sightseeing checklists and toward trips built around one big, unforgettable experience, and for a growing number of travelers, that experience is the night sky.
Searches for “astro cruises” have surged more than +1000% over the past year as people look for trips where they can stargaze or maybe even catch the Northern Lights. To see where the views are actually worth crossing an ocean for, global travel booking site Omio analyzed European destinations using two key factors: brightness value (how bright the sky is) and the Bortle scale, which ranks night skies from Class 1 (pristine, natural darkness) to Class 9 (bright inner city).
The results? A handful of remote islands, wild coastlines, and lesser-known spots that offer some of the darkest skies in Europe.
Scotland Is Europe’s Unexpected Stargazing Superstar
Scotland took the crown overall, with multiple destinations earning top marks for low light pollution and excellent Bortle scores — and all the dramatic scenery you’d expect up here in the north.
1. Outer Hebrides, Scotland
A short flight or ferry ride from Scotland’s west coast, the Outer Hebrides top the list for a reason. This chain of islands is known for rugged coastlines, white-sand beaches, and tiny villages — but once the sun goes down, the real show starts.
With extremely low light pollution and dark-sky ratings that put big cities to shame, the Outer Hebrides are ideal if you want Milky Way views and serious star fields. On especially active nights, you might even get a glimpse of the Northern Lights dancing over the Atlantic. It’s the kind of place where you finish a day of hiking or beach walking, bundle up, and then just… look up.
Travel logistics: you can reach the islands by plane from the mainland or by ferry, then base yourself in a small town or on a more remote stretch of coast if you’re really committed to dark skies.
2. Isle of Rum, Scotland
Also in Scotland, the Isle of Rum ranks as one of the top stargazing spots thanks to a Class 1 Bortle score — basically as dark as it gets. Rum sits about 15 miles off the mainland and is already known among hikers and wildlife lovers for its dramatic ridgelines, red deer, and wild feel. It’s now getting recognition for its skies, too; the island has been officially recognized as having some of the best night skies in the world thanks to minimal light pollution and its remote location.
This is where you go if you want adventure by day, galaxies by night. Think challenging hikes, wild camping, and then sprawling out under a sky full of stars with almost no artificial light in sight. If you’re chasing trend-worthy trips, Rum also fits into a broader wave of adventure tourism that’s climbing fast, with more travelers wanting multi-day hikes and off-grid escapes instead of resort stays.
3. Isle of Coll, Scotland
Smaller and quieter than some of its neighbors, the Isle of Coll still managed to land in the top 10 thanks to a Class 2 Bortle score and minimal light pollution. It’s another Scottish island where the skies are dark enough that you can see the Milky Way with the naked eye on a clear night.
Coll is a good pick if you want something peaceful and low-key: white-sand beaches, birdwatching, and evenings that are more about cozy pubs and star-spotting than nightlife. You can easily pair it with a broader Scotland itinerary, then tack on a couple of slow days here specifically to chase those dark skies.
Warm-Weather Stargazing in Croatia and the Canary Islands
If your idea of a perfect astro trip involves T-shirt weather and beach days instead of layering up, the data also singled out two warmer destinations: Croatia and Spain’s Canary Islands.
4. Garafía & La Palma, Canary Islands (Spain)
In the Canary Islands, the village of Garafía, on the island of La Palma, stands out as one of Europe’s top stargazing destinations. Honestly, the whole island is a star magnet. La Palma is known as the “greenest” Canary Island, and its combination of high elevation, low light pollution, and stable weather has made it a major spot for observatories and astronomy research.
A big portion of La Palma is recognized as a UNESCO Biosphere Reserve, which helps keep development and light pollution in check. That’s good news for travelers: you can spend the day hiking volcanic calderas or relaxing at the beach, then drive up into the mountains after dark to watch the Milky Way stretch across the sky.
On top of that, La Palma stays relatively mild year-round, so you’re not freezing while you wait for the stars to come out. It’s a solid choice if you want a mix of sun, sea, and serious stargazing in one trip.
5. Lastovo Island, Croatia
If you’d rather stay on the Adriatic, Lastovo Island in Croatia also scored highly in Omio’s analysis. Remote and far less busy than Croatia’s big-name islands, Lastovo is all about untouched nature, clear water, and quiet nights — which just happens to be the perfect recipe for dark skies.
You’ll get days of swimming, kayaking, and coastal hikes, followed by star-filled nights with minimal glare from nearby towns. Fresh seafood is a big part of the appeal here, too, so you can end your day with grilled fish at a local konoba and then stroll out to the water to stargaze.
Getting there is easier than it looks on the map: you can catch a ferry from Split, and the journey takes under four hours, making Lastovo feel remote without being a logistical nightmare.
How to Plan a Stargazing Trip in Europe
If you’re tempted to build your next vacation around the night sky, a few quick tips:
- Check the season and moon phase. Darker, longer nights (usually fall to early spring) will give you the best odds, and avoiding full moons will help you see more detail in the Milky Way.
- Look at actual light-pollution maps. Tools based on the Bortle scale and brightness value can help you go beyond marketing language and pick genuinely dark locations.
- Layer astro experiences onto a “normal” trip. All of these spots — from Scotland’s small islands to La Palma and Lastovo — offer hiking, beaches, and local culture, so you don’t have to be a hardcore astronomy nerd to enjoy them.
With astro travel and “dark-sky” adventures climbing fast in search data, it’s clear that more people are ready to trade neon signs for nebulae. If your ideal vacation involves staying up late and staring at the sky, these European destinations are a very good place to start.
If you’re more of a U.S.-based stargazer, I’ve also rounded up some of the best national parks for dark skies closer to home. And if you just love space in general, there’s a wild new discovery about a so-called “failed galaxy” with almost no stars that astronomers say could change how we see the universe.

Astronomers have confirmed the existence of something long predicted but never proven: a galaxy that never actually became a galaxy.
