Go deep below the Columbia Icefield in Banff National Park to “the most inaccessible place in Canada” with the 2020 Castleguard Cave Expedition. AquaticFilms/SpeleoPix
Hello from Canmore friends! I found out about this cave as well as your adventure from a chat with a local caver about Rats Nest Cave. I'm blown away at Castleguards beauty, but what a trek to get there eh?! Worth it to be sure, but it must be hella expensive to prepare for! Thank you for posting this and sharing your experience with the world! Happy Caving and Happy Holidays! 🌝
