Combo White: three-day winter trip from Athens to Mount Olympus, with hiking, ski and snowboard. The base is the Army's Mountain Warfare and Ski Training Centre (KEOAX) at Vrysopoules, at about 1,800 m on the south side of Olympus; you need ID at the camp gate. Friday 22 January: afternoon departure from Athens by coach or exclusive Combo vans, check-in at the KEOAX refuge or wooden cabins and dinner at the base. Saturday 23 January: the big winter ascent, following the ski-lift pylons up to the Kostas Migotzidis emergency shelter (2,340 m), then the demanding part to the peak of Agios Antonios (2,817 m), with its old abandoned meteorological station and views over the Plateau of the Muses, Mytikas and Stefani, the Aegean, Thessaloniki and Mount Athos, and, if conditions allow, on to Skolio (2,912 m), the second highest peak of Olympus (about 12 km, +1,215 m / -1,215 m, about 8.5 h, between about 1,820 m and 2,912 m; Combo Ride grade 2+, indicative and highly dependent on winter conditions). The big ascent is optional: if you skip it you can walk and play in the snow around Vrysopoules. Sunday 24 January: free day for ski and snowboard on the KEOAX slopes (three lifts, natural snow) or walks, then back to Athens before 23:00. A demanding winter route with a big climb, long hours and possibly snow or ice: no alpinist experience needed, but you must be very fit, have done demanding hikes before and have proper winter mountain gear and know how to use it. The final route, the peaks reached and the length of the ascent depend on weather, snow and the safety of the group; if Saturday is unsuitable the ascent may move to Sunday, and skiing depends on the weather and the lifts running. Two nights in the KEOAX refuge or wooden cabins (heated dorms, WC and shower, hot water), about 400 m slightly uphill from the camp gate (a tracked vehicle carries luggage if there is enough snow); bring a sleeping bag, towel and flip-flops. Meals and basic supplies at the Officers' Club and the KEOAX canteen (KaPsiMi) at low prices. The KEOAX ski area does not rent ski or snowboard equipment, so rent it in Athens before you leave (the organizers can suggest shops). Departures from Athens: Rouf 15:30 (corner of Amfipoleos and Konstantinoupoleos, opposite the suburban railway), Elaionas 15:45 (on Iera Odos), Kifisia 16:00 (Ilision St, at the Kifisia entrance from the national road, opposite Karras parquet). €225 per person, €35 less with your own car; €80 deposit. Up to 30 people. Registration until Tuesday 12 January (after that, ask about availability); full refund for cancellations until the same date.
