figure 45 minutes each way...plus time spent at visitor centers, eating, hiking, etc. We usually estimate allowing at least 3-4 hours in all from Castle Rock to the Observatory and back.

Thanks, I had planned on 4 hours. Then, I read someting about 90 min from Johnston Ridge Observator to I-5, and that seemed a bit long. Need to be in Portland at a certain time, and trying to figure out drive times, etc.
