Ongoing, originally posted in 2013 -- Annual closure in effect April 15 to June 15 (approx), closure is presumed currently no longer in effect for 2017 -- Due to grizzly bear foraging each spring, the Salmo Great Northern rail trail is normally closed annually for 10 kilometres between Cottonwood Lake and Hall Siding (northern section, about 8 km south of Nelson) from mid April to mid June. The trail operator, the Regional District of Central Kootenay (RDCK), is responsible for this closure. Users are asked to use the highway as a bypass route when the closure is in effect. Read more on the Regional District's trail page. Note, the RDCK rarely (if ever) updates this webpage . Signs are posted along the trail when the closure is in effect, but the only other way to know if the closure is in effect is by contacting the RDCK directly; call their main switchboard at (250) 352-6665.
