Belgium Hiking & Trekking Guide 2025

Local Hazards

• {'hazard': 'Hautes Fagnes Bog Terrain', 'description': 'The Hautes Fagnes peat plateau is criss-crossed by unstable boggy ground. Hikers leaving marked boardwalks can sink into deep, cold peat water. In fog (common), navigation is extremely difficult. Several hikers have died of exposure on the plateau.', 'mitigation': 'Stay on marked boardwalks and paths at all times. Hire a certified guide for off-path exploration. Check weather forecast — avoid the plateau in fog, heavy rain, or snow without experience. Centre Nature Botrange provides safety information.'}
• {'hazard': 'Rapidly Changing Mountain Weather', 'description': 'The Ardennes and especially the Hautes Fagnes plateau experience sudden weather changes. Clear summer days can become cold, wet, and misty within an hour. Temperature on the Botrange plateau is 5–8°C colder than lowland Belgium.', 'mitigation': 'Always carry waterproof jacket and extra layers even in summer. Check forecasts at meteo.be. Bring food and water for longer trails. Tell someone your planned route.'}
• {'hazard': 'Hunting Season', 'description': 'Hunting (la chasse/de jacht) is active in Belgian forests from September to January, particularly on Saturdays and Sundays. Hunters use rifles for deer, boar, and pheasant. Some forest areas are temporarily restricted during hunts.', 'mitigation': "Wear bright orange or red clothing in autumn/winter in forest areas. Look for 'chasse en cours' (hunt in progress) signs and avoid restricted zones. Stick to marked trails."}
• {'hazard': 'Unexploded WWII Ordnance', 'description': "In the Ardennes, particularly around Bastogne, the Hürtgen Forest border areas, and Ypres/Ieper in Flanders, unexploded WWI and WWII ordnance (the 'Iron Harvest') is occasionally unearthed by erosion, flooding, or agricultural work.", 'mitigation': 'Never touch or disturb any suspicious metal objects in the ground, especially in known battle zones. Report findings to local police. Stick to marked trails in historically sensitive areas.'}
• {'hazard': 'Flash Flooding in River Valleys', 'description': 'The Ardennes rivers (Lesse, Ourthe, Amblève, Semois) can rise rapidly after heavy rainfall upstream, particularly in spring. The Lesse valley below Han-sur-Lesse is particularly prone. Flooding events in July 2021 were catastrophic in parts of the Ardennes.', 'mitigation': 'Check river levels and weather upstream before hiking in river gorges. Avoid camping in river valleys during heavy rain periods. Heed warning signs at trailheads about flood risk.'}
• {'hazard': 'Slippery Wet Beech Leaves', 'description': 'In autumn and winter, fallen wet beech leaves make forest trails extremely slippery, particularly on slopes. This is a common cause of falls in Belgian forests.', 'mitigation': 'Use trekking poles on downhill sections in autumn. Waterproof hiking boots with good grip are essential from October–March. Take descents slowly.'}
