A little walk into the main cave at Upana Caves, up past Gold River, BC. We didn't go all the way in, due mainly to lack of gear. It looks fairly accessible though, just bring flashlights, good boots(it's wet and slippery!), headlamps and possibly a helmet or hardhat. Lots to see even from the entrances, with multiple caves to explore in the area👍Have a look at Stew's video too(WestCoaster on YouTube, link in my bio), showing how to get here and a more in depth look at the different caves at the site.
