What Are Coolcations and Why Are They Trending in 2026?
The term "coolcations" has exploded in popularity as travelers increasingly seek refuge from scorching summer temperatures that have become the norm across traditional European vacation destinations . Instead of battling 40°C (104°F) heatwaves in the Mediterranean, southern Europe, or other sun-drenched locales, smart travelers are discovering the joy of cooler, more comfortable summer getaways in northern regions .
Coolcations represent a fundamental shift in summer travel philosophy. Rather than chasing the hottest beaches, travelers now prioritize destinations with mild temperatures, lush landscapes, and outdoor activities that don't require constant air conditioning or siesta breaks . This trend has accelerated dramatically due to climate change, with record-breaking heatwaves making traditional summer destinations increasingly uncomfortable and even dangerous for outdoor exploration.
Belgium's Ardennes region has emerged as Europe's hidden gem for coolcations in 2026 . This forested highland area offers average summer temperatures of 18-22°C (64-72°F)—a refreshing contrast to the 35-40°C (95-104°F) experienced in Spain, Italy, or Greece during peak summer months . The Ardennes combines natural beauty, outdoor adventure, cultural richness, and comfortable climates, making it the perfect antidote to summer heat stress.
