Tom Bolton’s River Effra Walk

This event is coming up on Saturday 19th September. It should be an insightful event, exploring the area’s watery past and the influence that it still holds on local neighbourhoods and wildlife today. The walk will start from the Railton Road entrance to Herne Hill train station at 10am, setting off through Herne Hill and hopping on the bus for a brief stretch to end up on the Thames foreshore near Vauxhall Bridge at 12.30pm. Please bring an Oyster card or contactless payment card for the bus trip and wear shoes suitable for walking along pavements.

We are requesting a donation of £10 to cover the costs of the walk and you have the choice of either making a payment online in advance using Paypal or through a cash donation on the day. If you would like to pay in advance, please send a Paypal request for £10 to Tom Bolton at and feel free to get in touch with me or Tom if you have any queries (or need IT support!).

Finally, if you are no longer able to make it along, please let me know in advance so I can allocate the space to someone else and so that we know not to wait for you in the morning. I will have my mobile on me 07971 315 245 on the day.

Martin Knight’s Autumn River Effra Walk

When: Afternoon, Sunday October 11, 2015.

River Effra walks and talks are always very popular and a walk last year led by Effra expert Martin Knight was predictably over-subscribed. Here’s another chance to find out about our local “lost” river. First priority will be given to those who could not be accommodated on the previous walk, but all are welcome (space permitting).

We have received the following notice from Martin Knight: “We will be walking about 2 1/2 miles of Effra watershed from Upper Norwood to Hornimus, via Sydenham Hill. There will be no charge, but a small charity donation will be invited, as before. If anyone is interested they can contact me for further details.”

If you want to come please contact Martin by email (, or telephone (020 8693 8639).

Feedback on Effra Musical Walk (survey)

Friends of Belair Park reproduce this e-mail from Helen Spring, organiser of the Effra Walk:

Hello all,

I hope you all enjoyed the walk last Sunday and didn’t wilt too much along the way – what weather we had! Special thanks to Martin Knight for his time and effort in leading the walk and also to London Wildlife Trust volunteer Chris for giving some info about the work that’s been done to restore the Ambrook (one of the Effra’s tributaries) in Sydenham Hill Woods.

It would be a great help if you could fill in this quick online survey (only 8 questions and mostly multiple choice!), please find the link below. As this is a research project we are looking to learn from these activities in order to make the Lost Effra project a real success and run more environmental projects in the local area and beyond! It really shouldn’t take long at all and would be a huge help – thank you!

Please find the link here:

I will keep you posted about other Effra themed events this year, (please let me know if you would like to removed from the mailing list). For example there is a screening of a film called Lost Rivers at Greenwich Picturehouse, 7pm on Friday 6th June. It is being shown as part of the UK Green Film Festival, in association with Friends of the Earth. Special guest speakers including the film’s director Caroline Bacle, Roy Stephenson (Head of Archaeological Collections and Archive at the Museum of London), Tom Bolton (author of London’s Lost Rivers; a Walker’s Guide), and myself talking about the Lost Effra project and what we are doing to help minimize the risk created by having one of London’s lost rivers beneath our feet.

Please follow the link for more information and to buy your tickets:

Thanks again for coming along to the walk, I hope you enjoyed it and remember to look out for our picture on the Dulwich festival website that Fabian the photographer took at the beginning of the walk!

All the best,

Helen Spring
