People who stand in the middle of a narrow track and talk at you.
The nostril-clenching, gut-wrenching, eye-watering, throat-closing miasma of anti-perspirant, deodorant, perfume and aftershave that follows 'hygiene' obsessed tourists on popular scenic tracks.

Even more than that, the ones who act all innocent when you do the "can you not read or did you not see all the signs about Fuel Stoves Only, No Fires?" routine:
"Oh, we didn't see any signs" - Oh yeah, there are only four of them on every possible route into this spot, of course you missed them all.
"Oh, we thought it just meant on the beach" - Oh yeah, that's why the first sign is at the beach entry to the campground. (That is, the first one apart from the the one at the start of the track, the one at the entry to the National Park, the one at the main walker registration station, the ones at the previous campgrounds on this loop . . .)
