Lussier hot springs between Cranbrook & Fairmont is a neat stop, it’s how a hot spring should be, just some rocks placed to create a few different temperature pools where the spring discharges into the river. Pretty sure I saw some camping signage & campers nearby but that wasn’t on our itinerary so we didn’t stop aside from visiting the hot springs.
Seems the place might have family daytime & lord knows what @ nighttime, I’m picturing free-spirited nudists & hippies frolicking around under the moonlight
