The Brockville Railway Tunnel is a 525-metre passageway under the downtown core of Brockville, a small town just east of Kingston along the St. Lawrence River.

You can explore this glowing underground railway tunnel for free this summer.

The Instagram-worthy tunnel features a state-of-the-art LED and sound system which displays a colorful light show throughout the former railway.

Originally built between 1854 and 1860, the tunnel was restored as a dynamic pedestrian passageway in 2018.

The alluring tunnel is now a tourist hotspot and attracts more than 30,000 visitors annually. According to their website, the tunnel takes anywhere from 20 to 30 minutes to walk through.

The fully accessible tunnel opened back up for the season last month and runs every day 9 a.m. to 9 p.m. until Thanksgiving Day.

Face coverings and masks are not mandatory but recommended.
