Hellenic Mission organizes and/or coordinates outdoor activities that may take place in mountains, natural landscapes, remote areas or changing outdoor environments.
Participants understand that hiking, trekking, mountaineering and expedition-style activities may involve physical effort, altitude, uneven terrain, weather changes, exposure to cold, heat, rain, snow, wind, limited facilities, transport delays and other risks that cannot always be fully predicted or controlled.

| Hiking / Trekking | Long walking hours, uneven paths, elevation gain, weather changes. |
| Mountaineering | Altitude, exposed terrain, snow, ice, technical sections or demanding conditions. |
| Expeditions | Multi-day travel, remote locations, accommodation changes, transport delays and variable conditions. |

Participants are responsible for ensuring that their health allows them to safely participate in the selected Activity.

Hellenic Mission may refuse participation if, in its reasonable judgment, a participant’s health condition, fitness level, equipment or behavior may place themselves or the group at risk.
For demanding, high-altitude, technical or multi-day activities, Hellenic Mission may request additional information or a medical confirmation before accepting participation.
Participants must normally be at least 18 years old.
Minors may participate only where the specific Activity allows it and only with written consent from a parent or legal guardian.
Depending on the Activity, a minor may also be required to be accompanied by a parent, legal guardian or responsible adult.
Hellenic Mission reserves the right to set different age limits for specific Activities depending on difficulty, terrain, altitude, duration or safety requirements.
Each participant must bring the required equipment listed in the Activity description.
Required equipment may vary depending on the Activity, season, weather, altitude and technical difficulty.
Participants who arrive without the required equipment may be refused participation for safety reasons.
In such cases, no refund is guaranteed unless otherwise stated in the specific Activity policy.
Hellenic Mission may provide or arrange certain group or technical equipment when clearly stated in the Activity description. Any equipment provided must be used carefully and returned in good condition.

Outdoor and mountain Activities are highly dependent on weather, terrain and safety conditions.
The route, schedule, summit attempt, duration, meeting point or itinerary may change before or during the Activity if the leader, guide or coordinator considers it necessary.
Safety is always the priority.
A change of route, shortened itinerary, alternative destination or cancellation of a summit attempt does not automatically entitle participants to a refund.
Participants understand that reaching a summit or completing a specific route can never be guaranteed.

If the minimum number is not reached, Hellenic Mission may cancel, postpone or adjust the Activity.
Participants will be informed as soon as reasonably possible if this happens.
Participants must arrive at the meeting point on time.
The meeting point, time and other important instructions will be provided before the Activity.
