Signs at the park gates offer words of caution for climbers.  Here’s what they say: 

 POINTS TO REMEMBER

1. Hikers attempting to reach the summit should be physically fit.
2. If you have a sore throat, cold or breathing problems, do not go beyond 3,000 metres A.S.L.
3. Children under 10 years of age are not allowed above 3,000 metres A.S.L.
4. If you have heart or lung problems do not attempt the mountain at all without consulting your doctor.
5. Allow plenty of time for the body to acclimatize slowly.
