Apologies for my part, although I was just responding to the previous comment - adding a clarification. My previous point is very relevant, however, to any discussion about national parks usage. I know this because part of my work is just that.
There are signs - even in the US, who started the worldwide national parks idea - that there has been too much emphasis or leeway placed on the “recreational” use. Nature and a peaceful natural environment for humans are losing out. Canada is currently considering limiting visitor numbers in places like Banff NP, and discussions are likewise taking place in Zion NP in the US - so there’s little prospect of any lessening of regulations for drone flying in these special areas. Noise pollution is on the NPS (and equivalent elsewhere) radar and has been for some time - as with snow mobile usage in Yellowstone NP, for example. The tide is slowly but surely turning. And it takes time, just as the wolf restoration to Yellowstone took over 50 years to happen.....
Even if we all love flying our drones, there must be limits. I’m a huge fan of the US national parks and I know many forum members are American. The worthy ideals of making these exceptional natural places need to be upheld by the current generations. Yes, other countries today are also really good examples - South Africa, Tanzania, and Kenya being classic examples - but other countries need to do better. In the UK, our best national park is full of sheep (unbelievably). There are still countless other sites beyond national parks to fly our drones, (exceptions noted).
