Rilets, Mountain summit in Kyustendil Province, Bulgaria.

Rilets is a bare granite summit in the Rila Mountains of Kyustendil Province, reaching 2,713 m. It forms a huge pyramid-like peak on a short, hard-to-cross ridge, with large unstable stone blocks covering much of the summit and ridge. A pale grey-green metal plaque on a boulder bears the name "ВР. РИЛЕЦ" and honours Major G. A. Raynov, a national figure and state architect.

The peak was called Dzhendema until 29 June 1942, when it was renamed Rilets after the master builder Aleksi Rilets. The old Turkish name, meaning hell, is still used for the peak and its cirque. The plaque on the summit rock honours Major G. A. Raynov Rilets, a national figure and state architect.

The peak and its ridge were renamed Rilets on 29 June 1942 after the master builder Aleksi Rilets, replacing the older name Dzhendema, Turkish for hell, still used locally. The plaque on the summit boulder honours Major G. A. Raynov Rilets, a national figure and state architect.

The best hiking season runs from June through September, when snow has melted and trails remain dry. Access to the peak is via established paths starting from several locations in the lower valleys.

The summit's old name, Dzhendema, means "hell" in Turkish, likely referring to the surrounding cirque where vast fields of rock debris alternate with belts of nearly impassable dwarf pine. The peak was renamed Rilets on 29 June 1942 in honour of the master builder Aleksi Rilets.
