Aleko (Bulgarian: Алеко) is a site on Vitosha Mountain in Bulgaria situated at the northern foothills of Malak Rezen Peak (2191 m), in the watershed of Yanchevska River draining eastwards towards the village of Bistritsa, Sofia.
Aleko is the principal tourist and winter sports centre on Vitosha, offering accommodation at Aleko Chalet (1820 m) and few hotels, and several chairlifts, surface lifts and ski runs, cafeterias and restaurants, and ski and snowboard schools. The oldest and most popular ski run is Stenata (‘The Wall’), while the longest and most difficult one is ‘Vitoshko Lale’ originally built for the 1983 Winter Universiade held on Vitosha. Nowadays Aleko is among Bulgaria's top ski resorts together with Bansko in Pirin Mountain, Borovets in Rila Mountain, and Pamporovo in Rhodope Mountains.
