Secret object A
Secret Object A near the village of Kosharitsa is one of the most unusual and impressive abandoned facilities in the Sunny Beach area. Today, the place is a favorite among urban explorers, photographers, and people looking for something different from standard tourist routes.

How to get there:
The object is located a few kilometers above Sunny Beach, in the direction of Kosharitsa village. It is most convenient to get there by car. From the main road to the village, there are turnoffs onto wide dirt roads that lead to the hills. The last hundred meters are covered on foot. The place is not officially marked but is easily recognizable by the enormous concrete portal that suddenly appears amidst nature.
The road is accessible year-round, but it can become muddy after rain.
How much time to allocate:
About 1–1.5 hours are sufficient for visiting the object – enough time to reach it, explore the entrance, enter the tunnel (if you wish), take photos, and return. If you combine this with a walk in the area, you might spend half a day.
What not to miss:
Secret Object A impresses primarily with its scale. This is not a small bunker, but a huge, wide, and tall tunnel built of massive concrete.
The most interesting parts include:
– The main portal – impressive, overgrown with vegetation, with a characteristic industrial look.
– The long tunnel, which extends deep into the hill and plunges into complete darkness.
– The side niches and rooms, which hint at the planned infrastructure.
– The echo and acoustics, which create a powerful, almost cinematic feel.
– The surroundings, offering panoramic views of Sunny Beach, the sea, and the surrounding hills.
The tunnel is abandoned, undeveloped, and completely authentic – with no lighting, railings, or safety measures. This is part of its charm but requires caution.

Practical tips:
Bring a strong flashlight or headlamp – it is absolutely dark inside.
Wear sturdy, closed-toe shoes – the floor is uneven and slippery in places.
Do not visit alone – it is safer to be at least two people.
Beware of holes, metal debris, and unstable surfaces.
Keep the place clean – do not leave any trash.
