Welcome. I will be in camp that Sunday and I know of a few who will be there on Saturday.
Along I-70 you will be passing several. Just not sure if they are open because of the snow melt
Spring Creek Between Idaho Springs and Georgetown
Bill Moore Lake outside Empire -
There are a few more. Someone else will chime in on others and if they are typically open.
The best ones don't open til June and take you to the mtn peaks.
