If you don't want to visit me immediatly, there is also this map.
The High Tatra part was really nice, altough the eastern most third is very crowded. The rest is relatively quiet. There is a "secret" camping spot in the close to oko morskie (completely legal), they have their own tents and charge about 5 euros.
So you only need to take a sleeping bag with you if you wan't to do a similar hike.
I really like hiking this divide, because it takes you trough all sorts of mountains or plateau landscape, most of which aren't famous at all, so you get to discover things about our continent by yourself, which is very rewarding.
Also, the Rhine has 2 sources, arguably 3, because the Aare is usually bigger than him when they meet, so her source could also qualify as the Rhine source.
I happen to have the Aare just in front of my windows, and the old Aare (where it use to flow before we build some antiflooding infrastructure, which are very impressive in how efficient they are at preventing flloods in switzerland) about 30 minutes hike away. Old Aare is realy nice, they still let some water flow in it, so now, it a nice small river, most of it banks are protected against development and lovely.
