Kálymnos keeps upgrading also in June

Many climbers have long sung the praises of Kálymnos as a solid summer climbing destination—but I’ll admit, I’ve always been skeptical. Like many, I’ve traditionally stuck to the tried-and-true autumn trips. But after spending a week with my family on the island in mid-June, I’m ready to change my tune: Kálymnos in summer is an absolute paradise.

Summer Conditions: Better Than Expected
According to official stats, June is only about one degree warmer than September. But with the sun sitting higher in the sky, the shade lasts a bit longer in many crags, making afternoon sessions more feasible than you’d think. You can even climb until nine in the evening if you're motivated. During the last night it was actually a bit cold to eat in just a T-shirt.

The classic Kálymnos rhythm still works best: wake up early, climb until around 13:30, then shift gears to beach time and great food. That said, many crags—especially those around the Arginonta valley—fall into shade from around 13:00. And with so few climbers on the island in summer, you often have entire sectors completely to yourself. We even ended up doing double sessions most days.

Family-Friendly Upgrades
For families, one traditional downside has been the long or exposed approaches to some crags. But that’s changing. New concrete stairs, improved paths, and even small access roads have made many sectors much more approachable and less intimidating—even for younger kids. In the picture of Dolphin Bay, one suggested approach was actually abseiling; alternatively, ”scramble carefully down the scree in the steep gully…”

New Crags Worth Visiting
Kálymnos continues to evolve, and new crags keep popping up. Two recent favorites:
Little Eden: Just a 10-minute boat ride from the main harbor (free if you eat at the restaurant to the left in the square), this crag is a peaceful and stunning place to climb.
Gamos/Ruby: Located just above Arginonta, Ruby offers beautiful lines with incredible views, and is quickly becoming a must-visit sector.

On Route Wear
Yes, some popular routes are getting smoother from use. But rather than being truly polished, they just feel a bit more worn-in and less sharp. Still totally climbable—and still just as fun.

Final Thoughts
Kálymnos in summer? Absolutely. With longer shade, evening climbing, quieter crags, and better access than ever before, it’s a perfect time to visit—especially for those looking to avoid the autumn crowds. Whether you're pushing your limit or enjoying relaxed days with the family, Kálymnos in June might just surprise you.
