Parked close by in a pull in that suggested CCTV was in operation to deter fly tipping, walked back to the tarmac track leading to the high point. I found the grid reference in the grassy area containing the underground reservoir on the other side of hedge. The view from here was very good for a UA top especially from on top of the reservoir itself the Solent and the Spinnaker tower can be seen.WAYNE ROWLETT26/10/2019
From boat at Port Solent, a pleasant evening stroll to a superb viewpoint over Portsmouth. land very disturbed around grass covered reservoir. Retunred via Horsea Island bing.Denise 28/04/2019
Walked up from Port Solent. High point ill defined but great view of Portsmouth Harbour, city, Solent and Isle of Wight from top of reservoir.RichardM28/04/2019
Impromptu bag on way to ferry terminal and ferry to Caen. Also dubious bag but best I could manage on day given high point looks to be on MOD property. Parked in lay by to the west amongst fly tipping then walked up west boundary of reservoir and around North to find route all way round.. Not possible so returned on well trodden path through hole in fence round reservoir and ended up on access track on the east boundary. Ground clearly higher on east side of track and although managed to battle through undergrowth to get higher was confronted by high fence preventing further progress.SteveSmith13/01/2019
Walked up from Portchester station - top is difficult to distinguish as a lot of the features could be man-made, but is probably somewhere on the track to the covered reservoir. Also went to Fort Nelson, which is well worth a visit.Richard29/12/2018
A relatively short walk from home however I parked in the layby as I was heading to Wickham. Car sales outside the fort which is also park and ride for QA.Buck24/03/2018
On a dark night.....Nick30/09/2017
Parked in messy layby and got as close as I could. No access to the trig itself.mcc10/07/2017
Parked in the messy layby then walked round to this top and then was granted permission to access Fort Southwick trig plus conduct a llama welfare visit for the health llamas.Dugswell207/09/2016
Like others, parked in the messy layby. Splendid views of Portsmouth Harbour. Fort seemed pretty impregnable on this morning. Also 4/9/19 when I revisited as I Hadn't been into the reservoir compound on previous visit.Herbert Anchovy17/07/2016
Last top of a long day. (325 mile round trip)Climbed on top of Reservoir. Good views. Nice fort.electricratman10/04/2016
Great view!bolton09/01/2016
1/7 First climb of wet and windy day. All small due to inclement weather (Fort Southwick/Butser Hill/Wheatam Hill/Gibbet Hill/Telegraph Hill/Black Down/Linch Down/)Fergalh14/11/2015
Portchester circular (via ROW from NNW).Smudge06/11/2015
Same as NM. Also went up steps and inside Fort and wandered around car park. Much of land here looks man made. steps up to flag pole mast gave a good vantage point. Llama's on grass verge with some sheep seemed a bit incongruous.PeterD12/08/2015
From Layby easy enough, visited Nelson Memorial on the way past.rhalstead18/04/2015

Parked in rubbish strewn lay-by a little to the west then gap by gate-post saved climbing over the locked gates. Interesting area.Newton Maximus13/01/2014
walked with Bonzo on the way to the IoWmr bounce25/07/2013
P at ROW. Along rd and up track then on to top of res.chrisbien21/04/2013
Parked in small lay-by to west of fort. No problem with access into the fort up the steps in through the pedestrian arch, no one around to stop us. Never seen a submarine conning tower at a unitary top before! Lots of options for top, impossible to tell which (if any) of the mounds within the fort itself are natural. Walked around outside too to be on safe side.Hillsidenick22/11/2012
Stopped off here whilst visiting several county tops in Hampshire/Dorset Areamagirob10/10/2012
A diversion on my way back from Isle of Wight to the Midlands. Easy parking just to west on north side of road then a wander around the high points. Great views down into Portsmouth and back over to the Isle. Will have to come back fro the trig one day on a weekday I guess when NHS car park is open.Father Ted18/08/2012
Parked just west of the track and then walked up to the high point of the track. Walked along boundary in field but ground in fort seems higher. The fort appears to be an NHS car park for staff at the hospital down the hill so that may be a possible route - become an NHS worker.chriswatson16/06/2012
Easy parking. Very short stroll. Great views over Portsmouth if not misty.destaylor19/05/2012

Not the first time up here. Barbed wire replaced since last visit.stevebiswalkin15/05/2011
Walked up Crooked Mile Lane from Southwick and then a footpath to top of hill behind fort. Everything hidden away behind fences and gates.Overthehilljill30/04/2011
Date is an estimate, did several times as did park and ride for work from herefnem01/06/2010
Fine albeit mostly urban view. Had more or less given up on this one until I noticed asbown had wandered in and bagged it. So I did the same. One or two car drivers around; the burger van man; no-one else. Went in via the pedestrian entrance next to the bus stop. Shame its just a car park but impressive structure nevertheless. Flush bracket 2455 is fixed to the outside wall - half buried in surfacing. I had a Purbrook visit arranged for the morning and a Bembridge tour booked for the afternoon, so called here between.RHW20/04/2010
On way to Brittany Ferries Xmas mini cruise! Apparently there's 150,000 tons of fuel oil for the Royal Navy beneath your feet here!! The covered reservoir is higher than the tarmac but, like the trig, this looks outside the UA boundary!signyred24/12/2009
walked up the track to the resr and then visited the trigpoint, great views for very little effort.asbown19/11/2009
Came here trying to get to trig point in Fort Southwickdesperate dan01/11/2006
Where boundary crosses concrete track to covered resr. May be higher points within gorse opposite or within Fort or fenced off area - all inaccessible. Good view of Portsmouth harbour and Spinnaker Tower.webmaster06/04/2006
like many neaby trigs largely inaccessableRhayader_wander19/05/2005
Closest accessible point to trig is in reservoir compound adjacent to Fort - freely accessible through gaping holes in fence. Fort (and trig) itself appears impregnable!wheresthepath14/05/2005
