OK, I've spent the afternoon studying maps in the area, sorry I am not as familiar with them as you guys. I've got more information on them now.
I see the Oude Rhine, that comes out at Katwjik, past Leyden.
So they went up the Waal, from Wallahallagara/ entrance near Dordrecht - it goes past Tiel and joins the main Rhine at Emmerich, then head up past Bonn to the headwaters.
Then BACK - they come down towards the German Plain at Bonn, this is the beginning of the lowlands, pass Aachen 60km to the West of the Rhine, not exactly passing it directly but 'about' where it was - they then head back up the Old Rhine section past Leiden and out at Katwijk aan Zee (on my modern atlas map) - then head along the coast up to the Fly entrance (near Texel) past the Waraburgt to Alderga.
Also:
Abêlo, Jaltia’s husband; Grevetman over the Zuiderflylanden. He was three times heerman. The towns Aken, Liudburg, and Katsburg are under his care.
The whole area of the South Flyland (southern area of Zuiderzee)was Abelos juristiction - it included Aken, Luidberg (Leiden) and Katsburg - you think Katsburg is Katwjik?
Well done Puzzler. Just a minor detail you could not know: The Old Rhine at Katwijk was blocked by sand dunes. So, on the way down to the Rhine they traveled as far as Walhallagara and from there to the lower Rhine, called Waal. Similarly on the way back they could not leave the Rhine at Katwijk because of the sand dunes, but had to travel on inland waterways to the north. So they did not get to the Fly mouth, but to Forana (Vroonen, which is a lost city near Alkmarum-Alkmaar) and from there to Medeasblik (Medemblik) and crossing the Fly river to Stavere (Stavoren).
Well, at Katwijk was an old castle Brittenburg. This castle has disappeared, whether in sea or under the sand dunes. See my website:
http://www.rodinbook...rittenburg.html .
In Leyden (where passes the Old Rhine) there is an old castle too, which still exists. s.
http://nl.wikipedia....rcht_van_Leiden . In OLB Leyden is called Ljudburg, but is also indicated as Lyda's burg because of the black rowers, that live there. As the Old Rhine was blocked by sand dunes at Katwijk they could no more reach the sea and stayed in the place. By the way, the same happened at Alkmarum, where the former river Hegge was blocked by sand dunes at Egmond (Hegge mouth). There too the black rowers could not return to sea and stayed there.
Now we discuss here, if the third castle Aken is in the same area of Katwijk and Leyden or all the way down to the Rhine area in Germany. Both Abramelin and me think of Ocken-burg, where in Roman times existed a strenghold like the one at Katwijk (Brittenburg). In 1650 they built a new castle or house at Ockenburg, but that castle or house has been broken down. Now it is a golfer's place. Anyway Ocken-burg in Southern Flyland is a good alternative for Aachen in Germany. By the way from the above story you see that they traveled by boat over rivers and inland waterways.
As OLB speaks of pre-Roman times, the three canals that Drusus digged did not yet exist. One canal connected the middle Rhine at Leyden with the Helinium at Rotterdam, the second canal connected the Rhine with the IJssel and (according to Ottema) a third canal connected the IJssel with the Flie river as is indicated on his map).
