Nikko bus fares to the suburb areas?

We plan to spend a night in Nikko. The Nikko World Heritage Pass includes a round trip by Toby train from Asakusa train station to Nikko plus a two day unlimited travel to the temples and shrines in the Nikko Centre. How much are the bus fares to the suburb areas? Does any one know? I don't want to purchase the All Area Pass which costs more and good for 4 days which I don't really need. Thanks.

What do you mean with suburb areas?

By suburbs, I mean places outside Nikko like: Senjogahara Marshland, Kegon Waterfall, Akechiddaira Ropeway, Ryuokyo Canyon/Suspension Bridge etc.

Any suggestion to cover these places in two days?

Thanks.

- Senjogahara Marshland and Kegon Waterfall are both within Nikko. The town doesn't really have suburbs. There's a bit of development around the station, and from there it pretty quickly transitions into rural mountains with a few temples and inns.

If you go as far as the Senjogahara Marshland, then the All Area Pass will pay off even if you were to do it in just a single day.

Thanks so much.
