This section contains the answers to many of the questions that we are asked.  Please also see our Links to extended information

Where is the tunnel?  It is on the Water of Leith Walkway, in southwest Edinburgh.  Because it's a former railway tunnel it doesn't have a postcode (though EH13 OJX is the nearest), but the following Google Maps link is helpful in finding it:

The Google "Plus Code" is WP5Q+5X Edinburgh

If you're familiar with the "What3Words" geolocation system, the Colinton entrance to the tunnel is at: envy.pills.lands.  The Slateford entrance is at notes.quiet.sticky

What buses go there?  The 10 and 16 and 44 all serve the local area.   So do the 45 and the 400

What if I'm coming by road (car or bike)?   There is limited car parking under the Gillespie Road viaduct (accessed by a narrow road at the north end of the viaduct.  From the car park, follow signs along the Water of Leith Walkway towards Slateford, the City Centre and Leith.  The tunnel is only about 130 metres away.  If  you are travelling by bike, you can simply ride onto the Water of Leith Walkway from the car park.  If you're particularly well-heeled you can probably land your helicopter in nearby Spylaw Park (generous landing fees can be donated through our Giving page, please!)

Where are the nearest toilets? We have two pubs and two restaurants in the village, whose toilets are available to their customers.  Public conveniences are now open, just beyond the o-op store shown on the map above.  They are the newest public facilities in Edinburgh and, we are told, are unique in having hot water to wash your hands! Signposts from Spylaw Park also help you find them - it's about a five-minute walk so plan ahead.

When is the tunnel open and how much does it cost to visit?  The tunnel is on a public walkway, so it's open 24/7 all year long.  There's no charge for visiting, but if you like what we're doing please consider making a small donation.

Why do you think that the mural will increase footfall for Colinton?  We've proved beyond any doubt that it's bringing many more people to the area, as it has become a "destination" in the top ten things to do in Edinburgh.  Now that businesses are beginning to reopen they should start to reap the economic benefit of those growing visitor numbers.  Consecutive annual electronic footfall and wheel-turn counts have shown that visitrs have increased by 300% since we started, with an average of 1,000 people daily.  One wet Saturday last October saw 2,200 people pass through the tunnel.  Wow!  We're repeating our footfall and cyclist counts at least once a year.

What are you doing about the wet parts of the tunnel?  About 3% of the tunnel is damp or actively wet.  Our artist came up with a briliiant solution, which addressed that problem and gave other benefits.  9mm marine plywood boards with a waterproof membrane behind them are now attached to the walls in various parts of the tunnel, including the wet bits.  There is a gap behind them so that air and water can circulate, and they are removable for the Council's periodic structural inspections.  The boards can be shaped, e.g. cut out like a person or an animal, or left square.  That enables a sort of 3D effect in places, as you can see when you visit.  The smooth surface of the boards also enables fine details to be painted, which isn't possible on the brickwork.  Finally, the boards can be carried to schools, youth groups and other community participants for painting, taking the mural to them rather than needing to bring them to the tunnel.  After painting, they are varnished on both sides and fixed to the brickwork. It works brilliantly!.

Surely this project will just attract more graffiti?  This was also a concern of ours and we considered it very carefully. First, there is a body of research evidence which indicates that good quality public art tends to reduce the incidence of casual and/or antisocial graffiti. Some links to that research are at   We also consulted City of Edinburgh Council’s anti-graffiti specialists, who were unequivocal in saying that putting a mural in the tunnel is the best thing that could be done. We also considered, but ultimately rejected, using an anti-graffiti coating. That decision was primarily because, whilst affording limited protection, it would adversely affect the tunnel bricks’ ability to “breathe”, thus potentially causing long term damage. Finally, and pragmatically, we have accepted that there will always be a small risk of damage being done by a stupid minority, and our contract with the artist includes maintenance and repairs so that any unwanted additions are removed quickly.   Post-painting repair provision will be extended further as funds permit.  The theory seems to be valid - there hasn't been a single problem since we began.

How much will it cost?  The total project cost is just under £100,000, excluding ongoing maintenance costs - estimated as being up to £7,500 annually.  There may be additional minor costs for ongoing schools and community engagement events, but we plan that these will potentially be covered by income from post-mural merchandising and ongoing donations.

Did you have all the money before you started?  No, we did the work bit by bit as we could afford it!  Some capital projects require that almost all of the funding is in place before the project begins.  We were able to take a more flexible approach and dynamic approach and took the project forward as a series of mini-projects as funding permitted.  That was also helpful for our artists, who needed to have time available to address other clients' needs rather than having their time totally committed to our project.  We can receive donations through Virgin Money Giving, by QR code and by text message.   There's signage in the tunnel pointing visitors towards the ways that they can donate

How can I donate?   See our "Giving" page or use the link below to make a donation.  We're also constantly researching and making applications for grants and other corporate funding.  If you know of a grant-making body please let us know or suggest us to them.  You can also buy our souvenirs.

How are you advertising the mural? We now have a stunning images covering almost all of the tunnel, and we have gone very public!  Word of mouth is working well, as are social media and our website. The mural is is attracting visitors from far afield as well as from Edinburgh, we're regularly featuring in lists of top ten tourist attractions, we're getting some great press coverage, several tour companies have added Colinton Tunnel to their itineraries and we're featuring on national and international visitor sites.  Strangely, the more people that visit us, the more we hear about other people to want to visit.

When will it be done and how will you celebrate?  We originally planned to finish the mural by mid 2020, but then COVID-19 came along and two lockdowns threw our plans out of the window.  Our main concern was to have a high quality outcome, and quality is more important to us than speed.  We will now finish by Novemb er2021, but the COVID restrictions still mean that we won't be able to have a public event to celebrate.  We'll hope to do something aroud Easter 2022.  We'll be continuing fundraising to support maintenance, repairs, and any "nice to have" additions.
