Sunrise at 5:30 AM and temperatures from 16–23°C (61–73°F) mark the start of Interlaken’s high season. The Greenfield Festival brings 30,000 music fans, and the Tellspiele open-air theatre begins. Fête de la Musique fills the streets with live performances. All mountain trains, boats, and trails are open, and the lakes are warm enough for swimming. Accommodation fills quickly, especially during festivals, so book well ahead. Days are long and evenings glow with Alpine light—perfect for sunset hikes or lakeside dinners.
Pro tips for visiting Interlaken in June
• Book accommodation 4–6 months ahead for Greenfield Festival—rooms sell out and prices spike during the event. • Reserve Jungfraujoch tickets at least 2 days in advance—first trains are less crowded and weather is best in the morning. • Go early to Tellspiele performances for the best seats—open-air theatre is a local tradition. • Head to lake beaches in Bönigen or Neuhaus for swimming—arrive before noon for a quiet spot. • Avoid mountain excursions during afternoon thunderstorms—plan hikes and cable cars for the morning. • Choose weekdays for Ballenberg Open-Air Museum—weekends are busier with families and tour groups. • Pack for both sun and sudden rain—weather can change quickly in the Alps. • Visit Fête de la Musique events on June 21 for free concerts across town squares and parks.
