Paradise CG is up a very bumpy dirt road but you do NOT need 4WD. We drove up in our Ford Transit Van and there were low clearance vehicles at the trailhead. It is however very bumpy and the potholes will eat you up if you do not take it slow in some areas. Apparently the campground is full all the time but we arrived the last weekend of August and it was mostly empty when we arrived early afternoon on a Saturday. We picked a great spot near the trail which wasn’t very private but acceptable to us and our three dogs. While there we hiked the mile trail to the Rainbow lakes. At 10k feet we were winded but you can be a novice hiker and make it up to the top. We didn’t take the other 4 mile hike to the Glacier. Instead we hiked down the road along the river and saw a Mother and baby moose. Later that day while sitting in our campsite we saw a full grown black bear walking the trail above us. It was exhilarating and luckily the bear wanted nothing to do with us. Despite previous reviews, there is NO dispersed camping on the road in anymore. The bathrooms were clean and the host was great. No cell service on ATT Garbage is available but not water. If you can get a spot here it is worth it.
