Traveling with family (teenage children) who want to know if anyone has experience hiking (easy to moderate hikes) in the Swiss National Park. Is this park entrance and trails accessible to those traveling exclusively by train? Are maps available? Any special precautions for summer or fall hiking?
No experience there, but it looks like you need a Post Bus from Zernez train station to get into the park. Book lodging now as there are limited options and it is popular. Hiking routes here.
