My sister and I took our kids (aged 8-13) on a Family Tour of the caves. They have different tours available and some go very deep into the caves, so it's not for the light of heart. You must be able to withstand being in the deep and dark for up to 4 hours for some tours, as well as being able to repel to quite deep levels.
The tour we did with the kids was perfect and so much fun! We had a really nice guide, a young student, who took us up a steep trail to the cave entrance. The largest group they take is 14 plus the guide, so if you're a larger group I suggest you call first to see if they can accommodate you. We had to wait 90 minutes as they were already full and they do not take reservations except for the first and last tour of the day.
The caves are centuries old and the sides cannot be touched as the oils from our hands with damage the wonderful growths and designs that emerge from the depths. The cave bottoms are awkward and a bit treacherous as they are covered in large, awkward-shaped boulders, but it is really interesting to see what water and time can do to the lime formations. You must be sure-footed to be able to move within the caves. Dress appropriately in proper footwear and I suggest you wear a light jacket as it's only 8 Celsius inside the caves (year-round). It's a worthwhile visit to see these amazing formations as they are so rare. BC is one of only a handful of places in the world with caves like this, so it's a great adventure for a rainy day if you are visiting Vancouver Island.
The main office has chocolate bars and ice cream novelties for sale, but not much else, so I suggest you bring water and something to eat as you are definitely off the beaten track and there aren't any services around.
It's a bjt of a drive in from the main highway, and half of it is only oiled-over dirt road, but it's worth the trip if you want to try something novel.
Horne Lake is adjacent (hence the name). It's a lovely and large lake, but it's very cold to swim in.
This is a provincial government site, but there is no electricity or plumbing at the site but the office has a gas-powered generator and can accept interact and credit cards for payment. There are well-maintained outdoor toilets.
