I've been here several times over the years, but never used it as a naturist beach.  It's quite a muddy foreshore, especially when the tide's out but either way it's a pretty quiet spot so I should think anywhere would suit. There's also Park Shore a couple of  miles further east , (access down a long track I believe )- it's all private foreshore along here but used by beach anglers and few others.

If you're in the area , I can recommend Hordle Cliffs and Taddiford Gap ( west of Milford on Sea ) for skinny dipping. The latter has been an unofficial naturist beach for decades.
Also try the far end of Calshot beach , as with most of the Solent spots the sea can be very shallow a long way out, so check tide times.

TBH I never wear anything when swimming , if there's no-one around I'll swim anywhere at any time.

Thanks, much appreciated, will take your advice and head for Milford.

Went swimming at Taddiford Gap, Milford-on-sea, near Lymington yesterday and had the beach to myself for a while before one other naturist came along. Great place but sadly sunbathing was spoilt by too many flies. Going to try Birling Gap next, possibly over the weekend. Any thoughts?
