The cape projects about 4 km into the Black Sea and is the furthest eastern point of the Saddle Mountain Beach.
Viewed from the river Ropotamo, Maslen Nos recalls the outline of a lion's head.
Owing to the sharp rocks in the cape, Maslen Nos was notorious for ships that were wrecked there.
During the Ottoman Empire over this region (present-day Bulgaria) the cape was called Zeytin Burnu ("olive-bay" in Turkish).
In some older atlases, it was incorrectly labeled Cape Maslen Nos, which translates into English as 'cape oily bay'.
The lighthouse is a round stone tower with a gallery, painted white, 6 m high (with the pedestal for the light at 7.5 m).
South of the lighthouse, a 3m high square stone platform was built in 1937, on which a bronze fog bell was installed, to warn ships in foggy weather.
The old equipment was preserved and has been on display since 1977 in the Marine Museum at Warne (Bulgarian Военноморски музей Варна).
The river cuts through the slopes of the mountains from its source and winds through the Ropotamo Nature Reserve.
