Another shot from #LondonWNBR this year, looking forward to next year!
Already booked on for #NKD and #Everybody, both are #naturist events / festivals organised by #BritishNaturism
Last year I went on a #naked hike on News Years Day, any recommendations for where to celebrate a #HappyNudeYear?

Lazy #NakedSunday
Checklist: Entertainment, soft place to recline, no clothes.
Hardly rocket science.
And wide open curtains, ofc.
#naturist tip: Sofas with removable, fabric, washable covers. No one wants to stick to leather, and I refuse to perch on a towel in my own house.

Remember summer? *sigh*
But I won't despair! Plenty of #naked adventures in the winter, for the brave
And we can dream of when it's warm again. A #YoungBritishNaturism contingent at #NudeFest is being planned!
Under 35s: NudeFest 2026 is it! (And #NKD and #Everybody) (All welcome to all, ofc)

One more from #BudbySouthForest last week.
I went #naked from the car and left my clothes there for the first time. Would've left my shoes as well if it were warmer!
Just me, shoes, phone and car key, a properly wild feeling! Got asked directions by a clothed couple just after this pic.

No fires

A #naturist October stroll at #BudbySouthForest is a brisk but relaxing affair
All the naturism signs are up and clear, left my clothes in the car and spent 90 minutes there, a great time

#naked at #DruridgeBay #naturist beach, here I walked all the way back to the car without a stitch on!
Going to be at #BudbySouthForest tomorrow (1st Oct, pending weather). Plenty of opportunity for photos. I climbed trees last time, any suggestions for this time?

First time at #DruridgeBay #Northumberland today! An excellent beach!
I was the only person #naked on the beach, plenty of friendly dog walkers and fishers about
Not an official #naturist beach, but a strong tradition of naked bathing
Will be at Budby on Wednesday as well!

As summer draws to a close I'm already planning the #nudity next summer (and this winter)
#WNBR events for sure, lots more naked hiking, solo and groups.
I'm keen to push my #naked boundaries further. Maybe get into life modelling? I'm open to all ideas!

This time down by the #Cam at #Grantchester, #Cambridge
A couple of other #naturist picnickers around, several clothed fisherman and many clothed passers-by on land and river! But, of course, no bother at all 😁

More tree climbing from #BudbySouthForest!
I would make many of the snaps my profile picture all over social media. I don't think my friends or family would find anything shocking or surprising, maybe bemusing at worst. Alas, the platform's rules say no...

Fun? Yes.

Freeing? Certainly.

Makes your friends laugh? Seems to.

Back at #BudbySouthForest today (posting from the scene!)
When you're a #naked #rambler, shoes become the last item, and I do recommend sturdy boots! But it also means that when you do hike *fully* #nude, it sort of feels like the first time all over again!

Finding time to put together a little solo #nakedhiking guide
Spent much of Saturday #naked down by the Cam near #Grantchester. I was the only one fully nude amongst dozens of people, but no problems, though a few gasps.
Gotta own it.

PSA for public nudity in the UK
The College of Policing has published guidelines for the response to reports of public nudity
library.college.police.uk/docs/college...
It makes it very clear to call-handlers that simple public nudity does not concern the police.
Worth a read.
