A trig point marks the summit of a hill - well not always. These 1m high pillar of concrete painted white adorn our mountain and moorland environment. They were used for mapping and were key to the production of the Ordnance Survey maps we all love. By placing theodolites onto these trig points the angles to other trig points and key features could be measured. From this an accurate map can be made. These days the mapping is done via satellite and aerial photography making the trig points redundant. But the trig point still exist. Many trig points have been officially adopted my an individual or organisations and regularly visited and maintained - mainly a new coat of white paint.

There are 88 trig points within the boundary of the Peak District National Park. Whilst some are on top of the hills of the Peak District, others are on other prominent points. For the Peak District walker, one thing that can be guaranteed (on a good day) is that there will be a good view from the trig point after all this is why they were originally placed. A number of people see this list of 88 trig points as as a traget - let's try to visit all 88 trig points.
