Sofia lies at the foot of Vitosha mountain.
In Winter time you can even ski here.
We went to Rila & Plovdiv instead , though this is a great place to spend a day in nature with cable lifts taking you up once a day.
On clear days we had good views of Vitosha from the city and from the Slavia football stadium.
Rila monastery is situated in the Rila mountain. Its origin goes back to the eleventh century if your in sofia you must take the trips to the Rilla monastery it's the most beautiful thing you will see in your life the tripe is only about 20-30 minutes from sofi the monastery is like a piece of artwork.
Sofia is situated in the skirts of the Vitosha mountain which highest peak is Cherni Bruh (Black Peak -2990 m). Vitosha is of an easy reach from the city - there are regular buses to the cabin lift in Simeonovo which can bring you to the Aleko hut - a central meeting point for all tourist routes.
The longest cave in Bulgaria (17 600 m), Duhlata is at the back of Vitosha mount (considered from Sofia) near the village of Bosnek.
(these r the only pix i didnt take :)
When in Sofia, don't miss out Vitosha mountain. In the winter you can do some wintersports there, and the rest of the time, hike to the top. There is a very nice little place up there where they serve really good traditional bulgarian dishes, try one of their soupd, they are yummy.
Sofia is surrounded by several mountains -- Vitosha is towering over the city, but there are also Plana and Ljulin. If you stay an extra day, it may be worth going for an outing in the fresh, cool air. As a kid, my grandparents would often take me there for a picnic and a walk. The scenery is beautiful in all seasons (and actually, the winter was my fave).
BOROVETS is a winter ski and summer hiking resort in the pine-clad Rila mountains. We enjoyed a week of sunshine here in the snow-covered peaks taking it easy (see my Bulgaria page). The Rila range has the highest peak in Bulgaria - MUSSALA - at 2925m. The pic here just about shows a path (on the right-hand side) that we walked on, leading to the base of the Mussala.
You can eat there. It's far from the centrum but if you take a taxi, it will cost less than 15 dollars to go there - in Vitosha
while in sofia, you should visit the mountain vitoša, located just above the city (i don't think you can really miss it:) ). check out its weird big stones! incredible...
You can see Vistosha mountain easily from Sofia. There is a ski resort there as well as hiking trails and nice restaurants.
The ski lift up Mount Vitosha near Sofia. Friends of ours from Skopje drove over to spend the day with my husband and took him here.
