Hamstead Marshall is well served by public rights of way on which it’s possible to walk off-road through scenic countryside for an hour or more, hardly leaving the parish. Five circular walks are detailed below.

Old Mansion Walk

Just west of the White Hart, the bridleway begins a walk of nearly four miles, taking in the site of the old Craven mansion (which burnt down in 1718) and its Regency successor, Hamstead church and mill, before crossing the park and rejoining the Kintbury Road via farmland, and returning to the White Hart.

This can be combined with Holtwood Walk to make a figure-of-eight walk of about seven or eight miles centred on the White Hart.

Holtwood Walk

This three-mile walk starts opposite the White Hart, and takes the driveway up past Plumb's Farm, over a field, through Briffs Copse, across more farmland, and then joins a quiet lane to Holtwood. A footpath across farmland brings you back to the start.

This route can be combined with the Old Mansion Walk to make a figure-of-eight walk of about seven or eight miles, centred on the White Hart.

Walking with a buggy?

A public footpath follows the surfaced driveway into Hamstead Park from beside the mill and lock. About half a mile takes you through the parkland, around the lakes and up the hill. At the top the footpath leaves the tarmac to go over grass, so turn here and return.
Alternatively, the canal towpath eastwards from the lock towards Newbury is surfaced for bikes, and is a reasonably viable surface for buggies.
A couple more suggestions for buggy-able walks can be found on the 18 Short Walks page.
