It will be about 4.5 km walk from the Alma-Arasan Eco post to the barrier and parking lot (the beginning of the route to Kazachka). There will be another 2.5 km from the parking lot and the barrier to the Kazachka gorge itself, which makes about 7 km. The climb along this route at a fast pace of walking will be approximately such that, Judging by the chest heart rate monitor, your heart will be approximately in the 3rd and 4th pulse zones, which corresponds to 120-140, and 140-160 beats per minute, this is commensurate with jogging somewhere in the city. One of the advantages will be the constant noise of the river and the presence of phytoncides. Of the disadvantages, there is a complete lack of cellular communication.
The road, especially on the last kilometer - there is no road at all! Basically, for now, any car will pass. Snow will fall and there will be a collapse. It is very slippery to walk from the barrier. The road is well-traveled and well-maintained. No one cares about safety. A woman fell in front of my eyes. Fortunately, it fell successfully, did not hit anything and did not break.
It's still okay to go there in the summer, and in late autumn and winter it's not an option at all.
