The most direct route to Yogi Bear's Jellystone Park & Camp-Resort: From Hwy 400, go N or S to Simcoe County Rd 88 (formerly Hwy 88) exit 64 (W). Go W on 88. The entrance to Jellystone Park is the first driveway on the N side of 88, just W of Hwy 400. Look for the park signs and banners. Signage on Hwy 400 is restricted to camping icons before the exits. The finger signs on 400 ramps read Jellystone Park (that's us).
