The iron age hill fort that tops Trencrom Hill (also known as Trecrobben Hill) provides some historic and archaeological interest however, the main attraction of the hill is the wonderful views from the summit. Positioned at around 700 feet above sea level, you will have panoramic views across both coastlines. As you look clockwise from the west you will see Rogers Tower, Trink and Rosewall hills, St Ives Bay, the Hayle Estuary, Godolphin and Tregonning hills and St Michael's Mount.
If you are just visiting the hill itself, you don't have to walk that far; there is a small car park at the southern foot of the hill, on a minor road from Lelant Downs towards Cripplesease which can also be picked up from Trencrom Lane off St Ives Road. On one of the paths leading north off the hill there is a well, now sealed off with a padlocked metal cover. Apparently it is reputed to have holy properties but its great depth is considered to be a danger, hence its sealing.
