I have been there a few times in SUV and on a bike, if it not been raining I had been many worse places. It's around 10 km from the highway on a rough road with a beautiful view in the mountains, though I will not go there with a low tied car. The lake is nice, you can rent a floating cottage and bring your own food. The food you can buy in the restaurant is nothing special, I would call it a snack. I meet many Filipino on bikes with up to 5 persons on, impressed the way the can handle the bike
I have to admit that road conditions to this venue could need some improvements. However, I did make it up till the entrance with an hatchback last year upon special request of visitors staying with me, driving carefully so avoiding potholes and pebbles of unusual sizes. All in all a rather time consuming drive. Was there before on a motorbike (Yamaha 125 YBR) a bit easier.
