My husband and I want to plan a family holiday with our two kids aged 5 and 7 years to Leh in the months of June/July. We know that there are low oxygen levels in Leh, but how safe is it for kids to visit? Are small kids likely to get any problems when in Leh? What is the ideal age for kids to be in Leh? If it is safe to visit Leh, how many days would you recommend staying there?
