The Racoș Geological Complex covers an area of 95 hectares and is a nationally protected site located in the southeastern part of Transylvania, in the commune of Racoș. It is a geological complex that includes various formations such as the Racoș Volcano Crater, the Racoș Basalt Columns, the Emerald Lake, and others.

The Racoș Volcano Crater is a geological structure located in Brașov County, Romania. It is a volcanic crater formed by past volcanic activity.

The Racoș volcano was active millions of years ago, and its activity left behind a crater that can still be observed today by exploring this area. The crater can be seen near the Emerald Lake and the Racoș Basalt Columns. The Racoș Volcano Crater is a protected site, and it is important to respect conservation and protection rules in order to preserve it for future generations.

The Racoș Volcano Crater is an interesting destination for those passionate about geology and the geological history of the region.

The Emerald Lake was formed inside the former Brazi quarry. In the past, basalt rocks were extracted here. Basalt is a magmatic rock composed of iron and magnesium silicates, with olivine and pyroxenes as calcium-rich minerals, as well as feldspar. Due to its hardness, it is used for paving streets, railway construction, building materials, and as an ornamental element in landscaping.

It is a mountain lake fed by an underground spring. The crystal-clear water has an emerald-green color, which gives the lake its name and changes depending on the position of the sun throughout the day. The lake is accessible all year round, although it may be more difficult to reach during winter when roads can be covered in snow. Regardless of the season, the Emerald Lake offers opportunities for relaxation and exploration for both tourists and locals.

The Racoș Basalt Columns are an impressive geological formation and a nationally protected area. They consist of cylindrical columns rising from the ground, reaching heights of several tens of meters.

These basalt columns are the result of natural erosion and represent an example of columnar basalt formations, which are very rare in Europe. This geological formation is a popular destination for hiking enthusiasts, as well as photographers and videographers.

The Racoș Basalt Columns are protected by law, and it is important to respect conservation rules to preserve them for future generations.

Without a doubt, the Racoș Geological Complex is a must-visit destination for those who love nature and exploring unique geological formations. The volcano crater, Emerald Lake, and basalt columns are perfect for hiking, recreation, and photography.
