Does anyone know if all Trig Points are accessible to be viewed by the public, i.e. on footpaths or public land, or are some of them out of bounds or on private land?
Some are OK but others are on private land etc. You can always try to seek permission to go view. OS staff have right of access with prior notification.
A triangulation station, also known as a triangulation pillar, trigonometrical station, trigonometrical point, trig station, trig beacon, or trig point, and sometimes informally as a trig, is a fixed surveying station, used in geodetic surveying and other surveying projects in its vicinity.
