I think Rumple's castle is near Regina's kingdom, since Belle ran into Regina on the road and Regina in Season 2 had to go to Rumple after he failed to respond to her when she was disguised as a peasant. Also both places experience snowfall.

Assuming Phillip and Aurora were having a picnic within Phillip's and/or Aurora's kingdom, I'll say that it's near or bordering Regina's since it didn't take the group long to travel there.
