Mountain primes

The aim of the challenge is to visit a certain number of peaks whose altitude is a prime number. A prime number is a number that is divisible only by one and itself. Prime numbers are e.g. 2, 3, 5, 7, 11 etc.

Let's make walking on the peaks a little more interesting with a light mathematical insertion!

Repeated ascents to one particular peak are not accepted. However, it is possible to repeat the same altitude on different peaks.

An example of a prime number is e.g. 587. Thus, the first ascent to the top of Sturm's Hill counts. Another example of a peak with altitude 587 is Čistecká hůrka. The first ascent is also counted, even if you have visited a peak with the same altitude before.
