There's plenty to do here, but fair warning, this is a transitional weather time. It can be 60-65° in the day but 30-40° at night. Check with campgrounds to find out when they open, United CG and Alpen Rose are good choices. Forest CG's north of Durango will not be open yet.
The train does not start it's full run to Silverton till the second week of May, but does go half-way to a picnic area. Suggest you do some Googling or at least let us know your interests.
