Metropolitan Police Fishery

Climbs 7 – Rocktype Crumbly rubbish – Altitude 10m a.s.l – Faces S

Crag features
Very bad climbing on an old WW2 gun emplacement in the Lee Valley Park.

The 'rock' (concrete) is actually pretty solid. All climbs are 6m high.

There are currently six routes on the 'crag' ranging from moderate to very severe in grade, a bouldering grade is probably more appropriate.

Might be OK for drytooling, probably more suited to demolition.

There is often glass and porn strewn about everywhere. Probably the worst venue in Britain.


The Metropolitan Police Fishery has been declared a registered ancient monument! Fences have been erected along the canal-side face, blocking access; presumably this is also the case around the back. This means that the slick chimney classic Board Her in the Smoke is now redundant as you could stand on the railings and grab the top! The entrance to Dark Chimney is completely blocked. Other routes may well be affected.

It would seem that the history of East Hertfordshire climbing has blossomed and died* in the space of a few short years, with just a handful of enthusiasts having experienced its myriad but ephemeral delights.

*Or has it? The much talked about breach of the main overhang awaits - as do the spiky new railings below. Any takers...?

"went down today 19.07.08 and covered in glossy graffiti. very overgrown. would say it's not worth the effort even if you live next to it...."

Approach notes
Now fenced off and largely inaccessible - which is probably a good thing!

Approach from the second car-park across the tracks at Cheshunt station. Follow the canal south until the fishery appears high on the opposite bank. Cross the canal at the lock and double back along a muddy path behind the lock-keepers cottage. Alternatively, get back on the train and head in the opposite direction.
