And probably all for the cost of a single adult ticket to Disneyland.
Family Builds Mini Disneyland Matterhorn Roller Coaster In Backyard

Unable to visit Disney during the quarantine, the LaRochelle family of Napa Valley, California constructed this miniature version of the Matterhorn Bobsleds in their backyard, complete with caves, fountains and waterfalls. That…wow, that’s some real dedication. For reference, I would have just ridden down the stairs in a laundry basket and called it a day, and possibly even a life depending on how hard I hit the front door.

Keep going for the video, with a POV ride at 2:30. Also, I’m pretty sure they made that rock overhang too low to be safe at 2:13 (dude has to duck under it!).
