Canyoneering the Goblins Lair (Gobin Valley State Park, Utah) with kids!

Canyoneering (more like only rappelling) the Goblin's Lair (aka 'Chamber of the Basilisk' as it was first called) in Goblin Valley State Park, Utah.
I have done this rappel once before in 2012 with a bunch of friends and 10 years later, I wanted to take our kids through it for their first time!
It's about a 80-ft rappel, with the first 20-30 being at a wall with ledges, followed by a free-hang.
Goblin Valley in and by itself, is worth a minimum of a 1/2 exploration. There are many places to wander, get lost for a bit, and come up with a game to "try to get over there" and then make it happen.
I love Goblin Valley!
