I'm an American who moved to the UK 2.5 years ago but didn't start doing a lot of outdoor activities until early this year (here, specifically, as the job that moved me over was very demanding at first.)
As such, I'm trying to find documented and reliable information on Etiquette for hiking and scrambling that might not be the same as the US. Here are some specific examples, but a well written article from a reputable source that discusses discusses overall etiquette would be better than answers to these specific questions. Does anyone have such an article they could point me to? (Article could mean blog from a reputable source, vblog, podcast, magazine article, etc.)
1) In the states, we frequently say "on your left" and then pass on the left when we mean to overtake. This is true for bikers, hikers, parents with strollers, etc. Plenty of people, especially in areas with lots of novices, don't know what you're talking about, but it's a widely accepted practice. I've noticed almost no one in the UK announcing a plan to overtake, but is there an actual preference?
2) In the states, cyclists and hikers should yield to horses and cyclist should yield to hikers (even though most hikers who also mountain bike will yield, knowing how much more difficult it is on the cyclist to start and stop, the established etiquette is frequently sign posted.)
3) Priority for oncoming traffic of the same type. I've always heard that uphill hikers/scramblers should have priority over those going downhill. I was recently told this was not true in the UK and that people moving downhill should have priority. This was based on anecdotal evidence though of a crowd of people getting annoyed with a group who insisted on priority moving past a group of nervous children coming down a loose rock slope on Snowden in the winter.
