In reply to Kaito:
> (In reply to almost sane) I definitely read this too late- I've just bought a Olizane map! Would you say it is of a high enough quality to navigate with without a guide?
Even if it was 100% accurate, think of the scale. In Scotland I use 1:50,000 map with 10m contours. The best Olizane maps are 1:150,000 with contours at 100m. How much detail can this give? A 50m high cliff might not even appear. An 80m cliff might not appear!
Also, paths make such a difference to progress, and these can change from year to year due to landslides.
So my default position would be to use a local guide. Besides, this adds to the local economy.
That said, in more common routes like Stok Kangri, you might get away with just following the path. There are loads of route descriptions in books and trip reports on line. Likewise, some of the other hills are so rounded and obstacles so few that it would be relatively straightforward to attempt them without a guide. I am thinking of some of the hills round Tso Kar and Tso Moriri. Other peaks are more complicated
