This summer I’m going to visit Tara National Park by bike starting from Belgrade. I’ll first go to Valjevo for a few days (visit caves, etc.) and then directly to Tara.

Questions are:

1. How bad/good is the road quality? How wide is the road? How good is the visibility and lighting along the road?
2. How big a problem is it that I only speak English? Should I prepare some special phrases in Serbian for different cases or is it not necessary?
3. How much cash will I need? I prefer to pay with my Visa card.

Also, any advice about what to visit in Tara will be a pleasure!

Thanks in advance!
