Floe Lake and Numa Pass are part of the multi-day backpacking route between Marble Canyon and Vermillion Crossing in Kootenay National Park: the Rockwall. Most itineraries describe it as a four to five day adventure, and recommend starting with the trail into Floe Lake. Since we're strictly day hikers, we ascended the trail to Floe Lake for lunch, continued to Numa Pass in the early afternoon and retraced our route arriving back at the parking lot a little before 6 pm. A long and rewarding day, the Floe Lake backcountry campground has got us thinking about giving backpacking a try.
