Kii Katsura to koyasan

Hi all

Thanks and advance for any information. I have the following itinerary planned but I'm struggling to work out whether any of the available passes EG kansai wide pass or the ise kumano pass actually cover all of the routes below as I seem to get different information from different websites.

My plan is:

Day 1) Osaka to Kii tanabe and then by bus to Kawayu onsen. N

Day 2) next day go by bus to hongu taisha Mae and hike the area and on to kii Katsura (bus/train?)

Day 3) see daimon zaka and nachi falls etc by bus and go to Koyasan ( this is where I can't work out if either pass covers the full route)

Day 4) see Koyasan

Day 5) Koyasan to Kyoto

Any comments on how to make the travel cost effective or which pass is best would be super appreciated!!

Thank you in advance
