The best time to visit Rtanj
The same trail all twelve months, but the temperature on the bare rock and the ice at the summit change how comfortable the climb is — the table below gives the exact numbers.
- Best
- spring and early autumn

- Coldest
- January
The date here doesn't change the crowds — the mountain is too small for those — but how physically hard the Šiljak climb is: spring and early autumn keep the temperature at a level where the shadeless rocky trail doesn't turn dangerous. The month-by-month breakdown, with rainy days against each temperature, follows below.
Month by month
Average of daily means and rainy days per month, 2021–2024 (Open-Meteo).
Best time to go: spring and early autumn
The temperature at the summit stays comfortable for the climb, and spring and autumn share nearly the same dryness as summer, without its heat on the bare rocky stretch.
Summer
July holds the highest temperatures of the year, and the last stretch of the trail to Šiljak has not a single tree for shade — an early start, before ten, remains the only way to avoid the worst of the heat.
Winter
The limestone near the summit freezes over and the trail can turn slippery and icy, while the chapel ruins offer no shelter at all from the wind — the climb isn't recommended for inexperienced hikers in this period.
