The Subic-Clark-Tarlac Expressway. The missus, my boy and I spent the May 1 weekend at Subic and what a way to get there! It took as about 2.5 hours from our house to Subic (this excludes the traditional stop at the Shell station at NLEX which looked good btw after their renovation).
The P112.00 one-way toll was fair for the 94-km stretch unlike the P85.00 that one needs to spend at the SLEX-Skyway which is about <10kms(?).
However, I think the SCTEX management has to improve on the exit tolls. It took us quite a long while before we reached the exit toll due to the high volume of cars crawling towards the 4-lane exit toll.
Nevertheless, the ride was damn fast and smooth. The missus couldn't resist getting behind the wheel and stepped on the gas at 130kmh! Great ride indeed.
Here's a video I found on YouTube which is a collection of great pics of their ride in the SCTEX.
