Stay within the place
Use established paths and designated parking, observe closures and give wildlife space. Sensitive plants, nesting areas and wet ground can be damaged by a short detour, even when it looks harmless.
Carry out what you bring in, including food waste. Avoid feeding animals, and follow local rules about fires, camping and dogs; these rules vary by place and season.
Respect the people who live there
Public access and private property are not the same everywhere. Keep gates and farm access clear, ask before photographing people and avoid treating residential areas as photo sets.
Support local communities by being considerate of shared spaces and choosing locally available services when appropriate. Seek guidance from the relevant park or local authority rather than assuming a rule is universal.
