TucsonJim said it right. We have been there in March with great weather and in May and got snow. Last time we were there in March we got snowed in Trailer Village.
Taking the train gives you a couple hours or so midday at one central spot at the South Rim - visiting the Grand Canyon, yes; SEEING the Grand Canyon, no. You have to stay there to see all the spots and at beautiful sunrises and sunsets.
Go to www.LaurenBarbara.com and click on the Wanderings link on the left and then click Grand Canyon - Winter to see our last March visit there.
But it could be gorgeous ---- God makes the plan.
