To reach its summit there is a short but very steep path, first between mountain roads, then a forest path through something closed by brush but clearly visible and then up the slope (where you have to go down). It is not a suitable trail for everyone and it is not recommended to do it in the rainy season or if it has rained in previous days because it is exponentially dangerous since everything is on dirt and rocks and wet and depending on the area it can lead to an insurmountable fall.
