Thanks Enzian. We thought about reserving a site in the valley but we have a 40 ft motorhome and people are saying that the roads are narrow so we might be better off staying elsewhere.Im looking into that right now.

Two campgrounds in the Valley---Lower Pines and North Pines---do allow RV's to 40 feet. I believe the road in from the south--Highway 41 coming up from Fresno---is a bit wider, with broader curves, than the other choices, but someone local would know best. You would also have to meet the Wawona tunnel height max---10 feet 2 inches.

But there are lots of RV's on that road. I only meant to discourage you from a lot of driving back and forth, not from driving into the Valley to set up camp. If you do stay in the Valley you would only have to traverse that road once in each direction.

On the other hand, if you stay outside the park you could get a site with hookup.

W/ a motorhome - I'd never EVER stay outside the park and commute in and out each day. Why go in/out multiple times when you can just drive in, park the motorhome, and use bicycles and/or the shuttles to get anywhere and everywhere.

The beginning of April can be still winter at both parks. May is a much better month.

Some forecasters are predicting El Nino weather for this winter and, if that happens, we often get late winter and early Spring storms in the Sierra. You could very well have decent weather in April but there's always the possibility of getting caught in something nasty. Check the weather forecast carefully before you leave home.

And it can still be quite chilly at 7000 feet at the Grand Canyon in early April. Later in the month, or going in May would be better unless you are going to hike down into the canyon. April is a very good time for that activity.

Did I just read: "Went back with a friend last December and we both agreed it was nice, but there is nothing else to do once you have seen it! We came home from AZ 3 days early."???

I'm speechless!!! Granted, Grand Canyon would be a bit much for 4 days without hiking in but, I can think of lots to do in the area for 3 days without just heading for home.

Different strokes for differnt folks I guess.
