Very easy to reach from the city centre via the city park. But just need to be sure which trail to take. i was lost and a helpful local pointed me to the right direction and i hiked up to the top under the hot sun. I was the only one on the top. Very good view of the town up from there. It is a good start of your day trip in Maribor as it give you some orientation of this small town from Piramida.
