Mount Akhun Observation Tower, Agura Waterfalls and Eagle Rocks

Wedged between the Matsesta, Agura, and Khosta rivers in the Khostinsky District of Sochi, the forested karst massif of Mount Akhun forms the highest coastal prominence along the central Sochi littoral. Comprising three distinct ridges, namely Greater Akhun (663 metres above sea level), Lesser Akhun (501 metres, site of medieval Christian church ruins), and Eagle Rocks (Orlinye Skaly, 379 metres above sea level), the massif is honeycombed with more than 20 karst caves and clothed in deciduous relic forests supporting over 200 species of higher plants, including 34 species listed in the Red Data Book of Russia.

The 1936 Observation Tower on Greater Akhun

Reached via an 11-kilometre serpentine mountain road that climbs through oak, beech, and hornbeam forest from the Sputnik Hotel in the Agura Valley, the summit of Greater Akhun is crowned by a 30.5-metre (100-foot) Romanesque observation tower. Designed by architect Sergei Ilyich Vorobyov and constructed over ten months between 1935 and 1936 from dressed white local limestone ashlar, the tower is a protected architectural monument of federal significance. Wrought-iron grilles along its exterior staircase landings were crafted by Sochi sculptor P. P. Rochnyak.

From the crenellated upper viewing platform at nearly 700 metres above the sea, a 360-degree panorama encompasses central Sochi, the Adler coastline and Olympic Park in Sirius, the distant headlands of Gagra and Pitsunda to the south, and the 3,000-metre snow peaks of the Main Caucasian Range to the northeast. A short walk along the summit ridge stands the atmospheric shell of the 1937 neoclassical summit restaurant designed by architect David Chisliev.

Hiking Agura Gorge and the Three Agura Waterfalls

Four kilometres inland from the Black Sea coast, the Agura River cuts a deep limestone canyon protected since 26 January 1988. A well-trodden 2.5-kilometre trail carved into the rock walls with stone steps, railings, and bridges ascends from the Devil's Hole (Chyortova Nora) pool past three major cascades:

• Lower Agura Waterfall: Located roughly 1.5 kilometres from the trailhead, the first waterfall drops in stages into a wide, deep basin of milky turquoise water tinged by upstream hydrogen sulphide springs.
• Middle Agura Waterfall (500 metres further upstream): A 23-metre cascade plunging into a narrow rock amphitheatre.
• Upper Agura Waterfall: A 21-metre vertical chute above which the trail reaches the confluence of the Agura and its tributary the Agurchik at Glade of Rallies (Polyana Slyotov), where hikers can loop uphill to the summit of Mount Akhun or climb to Eagle Rocks.

Eagle Rocks (Orlinye or Belye Skaly)

Rising along the right bank of the Agura River two kilometres from its mouth, Eagle Rocks (also called the White Rocks for their pale limestone and yellow sandstone strata) form a sheer vertical precipice dropping 125 metres to the river bed and standing 379 metres above sea level. Crowned with pines, oaks, and oriental hornbeams, the clifftop viewpoint looks directly across to Mount Akhun and inland toward Mount Chugush (3,238 metres), Achishkho (2,391 metres), Pseashkho (3,257 metres), and the Aibga Ridge. Local Caucasian folklore links these crags to the legend of Prometheus, watched from the opposite summit of Akhun by the deity Akhyn while the maiden Agura brought water to the chained titan. Combine the gorge walk with nearby Stalin's Dacha and Old Matsesta.
