The Blackstone River is a relatively small, remote waterway in Yukon's Peel Watershed, rated Class I-II whitewater. The river flows east of the Dempster Highway through completely untouched and isolated terrain, covering approximately 140 km before emptying into the Peel River. Despite its modest whitewater rating, the river presents significant practical challenges due to its low volume — even modest rainfall can cause dramatic and rapid water level changes, more so than on many other rivers in the region.

A defining hazard throughout the paddle is the prevalence of woody debris. Strainers and sweepers are common, requiring constant attention. Paddlers are advised to stay on the inside of corners and to follow the channel with the most flow. The river is very low volume, which amplifies the effect of precipitation on conditions.

The typical trip down the Blackstone takes around four to five days of paddling, though parties often extend their time on the river with rest days and hiking. One group completed the paddle in ten days total, including hiking excursions. The surrounding landscape offers opportunities for significant elevation gain hikes, including ascents to ridge tops and peaks such as Mt. Bunoz, with views across the Peel Watershed. Grayling fishing has been noted at certain campsites, particularly near clear tributary streams.

Logistics at the takeout require careful planning. The Blackstone's confluence with the Peel River is remote, and returning to civilization involves one of several options: floatplane extraction, an approximately 10 km overland bushwhack through rough terrain, or lining a boat roughly 50 km up the Ogilvie River — a process that can take around four days. The drive between road access points on the Dempster Highway is approximately 1.5 hours one way.

Very few groups paddle the Blackstone each year, making it a genuinely isolated experience. Insects are a notable factor; bug jackets and repellent are strongly recommended from the outset of the trip. July is a documented paddling season, with trips recorded in mid to late July and into early August. Paddlers should contact local outfitters such as Black Sheep Adventure Sports regarding floatplane pickup logistics and current access conditions.
