Mount Olympus (Ólympos), Greece's highest mountain at 9,573 feet (2,918m), crowns the Thessaly-Macedonia border with three principal peaks forming a dramatic massif:
Skala (9,402ft/2,866m), Touba (9,186ft/2,800m), Profitis Ilias (9,199ft/2,804m)—bringing significant peaks to 6+. The massif spans 20km with 52+ distinct peaks.
Ancient Greeks believed the Twelve Olympians resided on Mytikas, shrouded in clouds. Modern climbing: June-September season. Prionia trailhead (1,100m) → Spilios Agapitos Refuge (2,100m) → summit bid. 6-8 hours round-trip from refuge. No technical gear needed for Skolio; Mytikas requires helmet, scrambling experience, nerve for exposure.
Olympus National Park (est. 1938, UNESCO Biosphere Reserve) protects 1,700+ plant species (23 endemic), chamois, wolves, golden eagles. The peaks' geological youth (uplifted limestone/shale from Tethys Sea) creates sheer faces, deep gorges (Enipeas), and spectacular wildflower displays in spring.
