We will be arriving in Warsaw in early August for a 6 day stay with a friend before going to Krakow for a few days and the Tatras for a week.
Our friend will be busy with work and am wondering about possible day trips once we have seen the sites in Central Warsaw. Don't want to go anywhere that involves travelling for more than an hour and a half each way and would be using public transport unless there are any reasonable organised tours.
Our interests are nature/hiking and social history. Lonely Planet mentions Kampinos National Park- not sure if we could visit in a day or should overnight?
