While the park is open all year, the major tourist season lasts from June to September. Most campgrounds are open from early May to late September while limited winter camping is available only at the Dolly Varden campground.
The park's main attractions include Olive Lake, Sinclair Canyon and the Paint Pots.
At the park's south-western entrance is Radium Hot Springs which offers a hot springs pool ranging from 35°C to 47°C (95°F to 117 °F).
The park takes its name from the Kootenay River, whose headwaters lies within the park.
