Environmental issues
The mining activities in Cobalt have left a significant environmental legacy. Millions of tons of mine waste rock and mill tailings were dumped on the land and in local lakes. In cobalt ores, silver was associated with arsenic minerals. Some of it ended up in the tailings and waste rock. Today this arsenic contaminates surface water in the area and is believed to pose risks to the environment. Sediment samples from surrounding lakes showed elevated concentration levels of nickel, copper and arsenic while water samples exceeded the provincial water quality guideline for cobalt and arsenic. Fish from five of the lakes around Cobalt had mercury concentration which exceeded the consumption limit as well as elevated concentration for arsenic. The Heritage Silver Trail is a self-guided driving tour of several mine and mill sites in the area. The trail is well marked, guiding visitors around the backroads of Cobalt. At each site, signs are posted, identifying the site, and providing a brief description of the site. The trail guides visitors to many of the remaining mine headframes in the Cobalt area, some of which are quite picturesque, and stand as an important reminder of Cobalt's past.
Visitors can also take a tour of an old underground mine. Tours start at the Mining Museum, and are guided by museum staff. The narrow damp tunnels of the mine give a real appreciation for the conditions under which miners worked, and tour guides sprinkle the tour with many stories to help bring the past to life.
On February 14, 2008, plans were announced to convert the vacant Fraser Hotel building into a complex which will include The Bunker museum, housing units, tourist accommodations, and a proposed culinary school.
Passenger rail service continued to be provided from the Cobalt railway station on the Ontario Northland Railway's Northlander train (it was during the building of this line that silver had been discovered in Cobalt) until it was discontinued on September 28, 2012.
A notable tourist attraction in the area in the 20th century was the Highway Book Shop, which closed in 2011.
