There are three National Trust car parks on Tennyson's Lane, which runs up Haste Hill from Haslemere. There are numerous footpaths from the surrounding villages, including a steep walk up the southern escarpment from Lurgashall. Blackdown is crossed by the
Sussex Border Path and
the Serpent Trail.
Tennyson's Lane is named in memory of
the poet who lived here. The lane is a
sunken, tree-tunnel lane that runs from Haslemere, past Aldworth House (today a couple of dwellings) to near the summit. The lane keeps to Arthur Paterson's description in 1905:
Trees meet overhead, copsewood surrounds it, and later, it is hedged by high sandy banks thickly overgrown with plant and scrub; squirrels and rabbits, and all other small woodland creatures, disport themselves over it. It twists and turns, and to the stranger appears to lead nowhere in particular.

The ownership of the Blackdown Estate can be traced back to the 14th century, to William Yaldwyn of Blackdown (1298–1375), who received the Patent of Esquire in 1330. The Yaldwyn family tree shows the estate as having been inherited by eight successive generations. William de Blackdown and Sutton (1342–1418) is said to have fought at the

Although the Yaldwyns had owned extensive farmlands in Sussex since at least the year 1300, it was William Yaldwyn the elder who succeeded to the property in 1600 and made full commercial use of the estate and surrounding lands. In 1627 he secured the sole right to purchase iron ore mined on the extensive Petworth Estate. This made him a wealthy man and by 1640 he had built the central portion of the present Blackdown House.

was said to have stayed at Blackdown House. Although the exact date of his visit is unknown, it was probably during 1644–45 when he went to assist the Earl of Essex and Sir William Waller during the campaigns in the west of England. The room where the Cromwell slept at Blackdown is still known as the Oliver Cromwell bedroom. The four-poster bed remained in the house until Blackdown was sold by
William Henry Yaldwyn (1801–1866) in 1844.
When Richard Yaldwyn died in 1807, the Blackdown Estate consisted of 1300 acres and included Blackdown, Brockhurst, Vale Wool, High Diddlesford, Cotchett, Reeth, Sheetland, Cooks Bridge Farms and Blackdown Cottage Barfold-under-Beacon. Many members of the Yaldwyn family are buried at St. Laurence's at Lurgashall.
In 1944 the then owner
W. E. Hunter donated Blackdown to the National Trust as a memorial to his wife. The Hunters are remembered by an inscribed stone seat at the Temple of the Winds. Today, the site is managed by the National Trust, with guidance and financial assistance from the Blackdown Committee of the National Trust.
