• Access rights (also for the amenities): You have to be a contributor and member of a UIAA-affiliated federation. People from the NKBV need the additional subscription for Belgian rocks.

  • Groups need to register at the CAB (mostly also possible via the Dutch-speaking KBF). Space for groups is limited in Freyr. The offer of routes, the non-commercial bolting and the peaceful nature of Freyr don't suit groups very often.

  • No abseiling allowed in the weekend.

  • Rockfall possible! Goats or tourists on top can kick down stones. Besides, loose rocks can be expected in every crag, yet mostly in Le Pape: sector Jurassic Park followed-up by rockfall around La Jeunesse, Al'lègne: sector lower part (Love Me Tender) and Tête du Lion, certainly after winter. Other crags are prone to rockfall too, just like any rock crag anywhere.

  • During the breeding season (February/March 'till the last day of June) many holes in Freyr are occupied by falcons (mostly Le Pape), owls, wild pidgeons,... Do not disturb nesting birds and inform the manager (CAB).

  • Careful on the top hikes. On average 1 person each year dies in Freyr, mostly by falling off the top or because of abseil installation errors (see newspapers).

  • The available protection doesn't always allow goofing and messing around. Be aware, read the rock, get adequately educated before you get here and assess risks. Freyr is not a drive-in playgarten. Some protection gear is old, rusted and untrustworthy. Sometimes the first bolt is high. Freyr is notorious for no-fall zones and unannounced runouts.

  • From time to time the military trains on Merinos. Ropes and rocks may be thrown down.


    Even just on the pages with the alpinist accidents there tend to be at least just as much reports of fatal bike, car and motorcycle accidents near the Freyr rocks. However over the decades the accident ratio of traffic has been diminished. Climbing accidents can also be brought back, not by haltering climbing but by training and guidance. This paper poses epidemiological indications of how proper use of helmets, experience and self-reliance are preventive factors that can decrease accidents.

    It may seem that tragedies almost exclusively involve beginning sectors Mérinos and Jeunesse, along with accessible grade multipitches on the other walls. Some derive that the danger is mostly among beginners since a beginner implies danger. This however cannot be concluded from this information: 1) beginning grades don't necessarily equal beginner practitioners, 2) the amount of climbers who venture into accessible grades is far larger compared to those venturing into the advanced grades, making them well represented in climbing and not easily overrepresented in specific statistics, 3) the sample is small and anecdotal rather than statistical, moreover it's mostly during course exams (and assorted events) that mistakes or non-fatal accidents get reported. The majority of events is not reported.

    Yet it must be said that Mérinos and Jeunesse probably traditionally are most bolted of all sectors in Freyr, though that's still less than modern standards. Yet in 1963 Lionel Terray would have stated that Freyr had the most bolts of all climbing places known at that time. In 1964 Claudio Barbier wrote an article on how too much fixed gear lures climbers into adventures that are beyond their current skills to make it right, safe and pure. This website, alpinism by fair means, tells the story of the 1968 'piton war' when police for instance rang a door in Mechelen. Eddy Abts opened. His house had to be searched. Conservative club-climbers had filed complaints against him and three other youngsters around the country for the theft of pitons from the Freyr rock. Indirectly the rigid club men contested the free climbing (avant la lettre) of Claudio Barbier and the gearless climbing of Jean Bourgeois. The move of the old CAB officials fired back as the moderate people sided with the less extremist youngsters. The CAB officials were relieved of their duties.

    For international statistics on rock climbing accidents (of which one can learn) the DAV is probably the most inspiring pioneer providing updated reports.
