We followed "dreamster"s post below (that stated do not take the road from Georgeville). CLEARLY THIS PERSON IS UNINFORMED because Chiquibul Road from Georgeville is just as bumpy/unpaved as Chiquibul Road from Santa Elena/San Igancio IF NOT BETTER. Not to mention, the road from Georgeville is shorter (by at least 45 minutes) as well.
We were in a compact car without 4x4 so we ended up skipping this due to the terrible, unpaved road. We weren't sure how much more the car could take AND it took us 1.5 hours to get to the intersection (not even the falls themselves). We inquired about a taxi, but it was insanely expensive & we were told by a local all the taxis are cars without 4x4.
