agree on the tagaytay route.
on the jungle route, as caloy said there are not that many landmarks to base on except. here's what i recall (please correct me caloy if i miss anything):
1. south luzon - yes
2. star toll - yes
3. lipa - yes
4. from lipa, drive past the road to leading cuenca/alitagtag.
5. when you see the white pedestrian overpass - go slow
6. there will be a white-painted house to your right at the corner of the intersection. intersection has a small traffic light (yellow caution light only i think). turn right here.
7. go straight until you hit a diagonal road intersecting/merging with this road on your right (you'll see a basketball court separating this road from the other). travel from end to end should be around 30-45 mins (est). at this point you're back on the road which originated in lipa/cuenca.
8. not too far from there would be the funeral parlor where you usually turn right to bauan and left to the road leading to anilao.
i guess you know the rest
Thanks for the direction, we'll give that a try if I'm driving...when you see me remind me to tell you about my experience in Cuenca early one morning headed to Anilao. It involves the CR at small Petron station on the Cuenca road :11:
