When you are in Baku, and most likely stayed at the coast, you'll see this mountain. I stayed on both sides and had some further investigation into this. I figured it would be "Beverly Hills" style fancy houses up there due to the nice view but aside from a few it wasn't really the case. So when you are the bay you will see this across the entire landmass. It's IMPOSSIBLE to miss. You perhaps don't realize it's just a narrow mountain range from this side. It goes back down on the other side but it is much higher up too. The main road also goes around the bay so you will not have to drive up unless you are actually going to the mountain range.

I was on the west side first and then searched for spots to look beyond to the coastal bay area. There were two on the map. The first was north which actually said it was hiking. It's hot here so that wasn't the best idea in the first place but even then it didn't have proper pictures. The second was the southern lighthouse. From here you can see the southern bay area.

To get up here you have to drive to the neighborhood just to the north and a gate will lead out. You still want to be in the car going out as it's quite a bit to walk. Do NOT continue driving down. The map says it's the way to go but the company below got shut at some point and locked the only gate through thus you have to drive back up and leave via the aforementioned neighborhood. It's not a long detour but the ascent/descent is quite hefty.
This "lighthouse" is maybe in use but not sure it's really useful for more than showing flights that there's a mountain up here. I suppose there is a good reason for it. Although the lighthouse is fenced off as the picture shows it was actually open and you could go in AND even go up... I didn't. Past the lighthouse is the best view of the mountain to the west as it drops off right after. With some wind it was sometimes a bit scary to be up here too. There is also NOBODY here especially during a hot day.
From the bay I also looked up at "Baku Stage" to check it out a bit more. At the Baku Eye where it ends you can see it along the bay and it's quite epic but that's about it. I also think most people just see it that way and that's enough. It definitely does NOT need to be inscribed.
