My 4 year old loves all the Camp Snoopy rides, the Log Ride, Mine Ride, and Beary Tales.
That being said, she spends a ridiculous amount of time climbing around that one log tunnel thing and those little mushrooms right by the Camp Bus/Timberline Twister/family restrooms. If they are getting rid of those two rides, I would love to see a playground go where they were as footprint wise, it would fit; especially if they absorb the bathrooms.
If they have a grander plan, great, but I recall the old Beary Tales funhouse being somewhere around that area of Knott’s, and wouldn’t mind there being a legitimate playground in the park somewhere.
