Summit, then other 158 SH and trig. Plenty of parking spots. | PGCE | 30/10/2020 |
Interesting hill fort, impressive extent. Walked round W side (with HP); E side disappointingly overgrown. Parked at car pk at foot of Slanting Hill | pwheeler | 25/09/2020 |
1st of 4 hills on a traverse from Hermitage to Wickham Heath and the last trip for a while due to the Coronavirus pandemic! Train to London St. Pancras, tube to Paddington, train to Newbury and bus to Hermitage. Explored the interesting ancient ramparts in the beech woodland (preferred top) then continued via 158m spot near road, visiting trig en-route then continuing to Snelsmore East Common... | Dazingdale | 21/03/2020 |
10 degrees, sunny spells, stiff westerly breeze. | Wycombe Wanderer | 24/12/2019 |
As per others, parked at the info board by the unusual Grimsbury Castle house and then walked around the iron age fort. No clear high point, but very pleasant woods. Some very polite local teenaged were doing spectacular BMX jumps over the ramparts. Oddly, later on at a craft beer shop in Newbury I saw and (and obviously bought) a beer called Grimsbury Castle made by the local Hermitage brewery - I'm a bit of a sucker for beers named after hills. | wheresthepath | 28/07/2019 |
HP is probably on beech covered ancient earth bank but hard to say. Lovely beech woodland with blue bells. Trig visited too. Free parking at road junction. Public access. | Denise | 27/04/2019 |
Superb Beech woods. A wander around the earthworks, high point on W side of the road then through woods past grove of Redwoods to trig pillar. | RichardM | 27/04/2019 |
From small car park at junction to NE then up through woods | Mark Sims | 27/03/2019 |

Short walk from interpretation board. | Bramley | 30/11/2016 |
Quick walk up from our house & did the trig point as well ( which is to the S ) | DanMaisieBex | 26/11/2016 |
Parked near interesting cottage for a short amble into the wood. | Dugswell2 | 03/11/2016 |
Boxford to Hermitage. | Smudge | 28/10/2016 |
An unusual quirky summit cottage in the woods next to this pleasant woodland. Just along from Downe House girls school where Kate Middleton went to school age 12 from her prep school but left (for co-ed Marlborough) after 2 terms due to allegedly being teased / bullied. | Chris Pearson | 25/05/2016 |
Parked by the interpretation board and wandered into the woods. Fairly pleasant spot I suppose. | Herbert Anchovy | 16/05/2016 |
Easy access from parking area. | rhalstead | 13/03/2016 |
Iron Age hill fort rampart to west of road with tree seems to be high point. | ngthack | 29/08/2015 |
Nice spot: meant to be the last hill of the day before driving home N, but found navigating off the A34 rather complicated, so visited this first of the three N of Newbury | GordonAdshead | 16/08/2015 |
Couple of possible HPs. Earth bank to west of road with tree at top may be it. | PeterD | 04/07/2015 |
Nothing positive to say, except can park in entrance to reservoir near the top | Hillsidenick | 28/07/2013 |
Visited to bag the trig pillar. Nothing much to see here, top not obvious. | jonglew | 01/06/2013 |
walk all around the area to be sure. | Adrian | 03/03/2011 |
