Kathleen Lake sits inside Kluane National Park just off the Haines Highway, and what you really need to know is practical: there is a small frontcountry campground with lakeside sites, pit toilets and a boat launch, but no RV hookups and limited services so bring your own water or treat lake water.. You can paddle on calm days, but summer bugs and changeable mountain weather are real factors, and cell service is unreliable, so pack layers, insect repellent and a paper map or offline directions.
