The first core day should usually be the one that helps set rhythm
This is not only about scenery. It is about what kind of day the family should use to stabilize breakfast, departure and return timing.
On a first Ili grassland route, that setup function often matters more than scenic ranking.
Nalati first usually gives the group a cleaner grassland starting point
Nalati often works well as the first big task after entering the grassland section because it helps the group learn its real pace.
That is especially useful for seniors, children and anyone new to the region's road rhythm.
Bayinbuluke later often works better as a back-half target day
Once the family already knows how it handles the route, a later Bayinbuluke day is easier to support.
When placed too early, the issue is often not the sight itself but the fact that the group's pacing has not settled yet.
Bayinbuluke first makes sense mainly when the front-end is already very light
If the previous night is easy, the group is strong and the back half has obvious recovery room, Bayinbuluke first can still work.
For many first-time mixed-age groups, though, rhythm first remains the safer default.
