Not been there yet, hopefully Sept this year. I usually check OSM areas that I look to visit so I can improve the map as much as possible before a visit. Then take notes during the visit. 
I am trying to get some consistency across the Munda Biddi campsites. 
Basicity I think the tourism=campsite should contain the hut, toilets, water, bicycle parking and tent pitches. The sites here would be tagged as pitches .. as per the OSMwiki and what has been done at another Munda Biddi site. 
On the visit I hope to detail track surfaces and camp site approach trails as access=private, bicycle=yes. + anything else I think of. 
Any thoughts?
