The estate is at the heart of the Lizard with Rococo gardens and walks leading on to the Goonhilly Downs and secluded walks down to Helford River and Tremayne Quay built for Queen Victoria's visit in 1847 (Now owned by the National Trust)

Large parts of Trelowarren are an 18th century designed picturesque landscape. There are Pleasure Grounds, a Mount , ha-ha's, avenues and terraces to explore. The Pleasure Grounds contemporary to those described by Jane Austen in Northanger Abbey and Mansfield Park are being replanted to the 1750 plan of Dionysus Williams.

Also on the estate are several Iron age earth works including the Halliggye fogou, (a series of neolithic underground chambers and  and passageways). Halliggye fogue is one of the best examples of a fogou in Cornwall and it is especially unusual in that it situated on the Lizard.

Trelowarren has been owned by the Vyvyan family since 1427. The Vyvyan's were originally from Treviddren, St. Buryan and became the owners of Trelowarren through marriage in 1427 to Honora Ferrers daughter and heir of Richard Ferrers of Trelowarren.

The most famous member of the Vyvyans was Sir Richard Vyvyan the 1st Baronet. A painting by Sir Anthony Van Dyke of Sir Richard and one, also by van Dyke of King Charles I presented to the family by Charles II still hang in the house.

In 1995 Sir Ferrers Vyvyan Bt. inherited Trelowarren House and gardens together with an estate of 1000 acres of woodland and farmland. Sir Ferrers has set about restoring the estate to its former glory utilising green tourism and environmentally sensitive development to convert a wide range of cottages and redundant farm buildings to time share properties.

The Estate has a specialist nursery offering a wide selection of plants including Fritillarias, Eremurus, Alliums and Lilies, as well as herbaceous perennials and culinary herbs.
