Hi, my friends are I are going on a day trip to the black forest. I realise that is not enough time to explore it completely, but was wondering what were the essentials to cover. I was thinking if would be good to take a train ride around the forest (how long would that take) and maybe hop on/hop off at some stops. Also, we were interested in hiking maybe for half a day, so are there any short hikes that are scenic (maybe around the cuckoo museum?). Is there a railway system that would take me around? We plan to come in from heidelberg to freiberg first, and from there go on to somewhere, and come back to heidelberg by night time.
