Parked in the large cp at the retail park on Marine Keep. The authorities are trying really hard with this tip and we are rewarded with considerable birdlife already. Portsmouth needs a bit of height! Well done, Pompey.Campbell Singer25/05/2019
Great views over Portsmouth on a lovely evening, with boat moored at Port Solent Marina. Trees are growing fast, more being planted and work ongoing. More a tump than a Sib, it seemed?Denise 28/04/2019
Easy access from the WNW. Horsea Island Country Park. Lansdcaped landfill site with well established grassy summit. Sides currently being planted with trees. Fine views of Portsmouth and harbour.RichardM28/04/2019
The new much advertised La La Land film was playing at the packed cinema below whilst outside I found my own La La Land as I disappeared into the welcoming bubble of darkness on a night ascent of this strange new hill. No trees, no bushes, no people, just vent pipes sticking out. A small oasis of empty calm surrounded by the rush of 24 hour lights and noise. An embryonic path was being laid leading to the top - for future La La baggers. Thinking about it, La means pass in the Himalaya so maybe that is the real La La Land with its many passes and not here after all? Doolally land here instead maybe?Chris Pearson18/01/2017
Parked in large car park then around the back over minor fence before being challenged by man in van on the road. He gave me ten minutes to bag the grassed over former tip.Dugswell207/09/2016
3 mounds S and E of the recycling centre, all ex-landfill with numerous vent pipes protruding. Middle one is clearly the higher of the 3, measured them at 27m, 38m and 31m. With a 3m col there is potential here for a tump.jonglew31/08/2016

Good to be able to log this one as it was my historic map research that led to it being added as a SIB.Swindon Bagger22/09/2015
