Over my 5 years at Cal Poly San Luis Obispo I went on quite a few outdoor adventures. Keep checking back because I will keep posting more as I have time. If you have questions please feel free to ask. We were never bored living in SLO.
So the first place in this series is called "Reservoir Canyon Water Fall and Tunnel". It is one of the easiest places to get to, probably 5 minutes from downtown San Luis Obispo and less than a 2 minute hike. Here is an abbreviated map from the 101.
You will exit off the 101 before you turn the corner to go up the grade. The road will go about .5 mi till the gate and you cannot go any further. Just before that there is some parking to your left. On the weekends there might be a couple cars.
From where you park your car you should hear the waterfall, just walk about 100 ft to the west.
Depending on the time of year the water will be flowing different amounts. But it is always accessible, just scramble across the front of the falls and you will be treated to the entrance of a long tunnel. This is where you hope you brought a head lamp and a few lanterns. It is a bit wet inside so also have shoes on you don't care about. I have heard a few stories about this tunnel. (A boy scout leader we met there said it used to be over a mile long and used like a bomb shelter during WWII)

Not sure what is true but if you make it to the "end", you can tell that it has been poured with cement to close it off. It is still probably a .25 mi (deep). And it is obviously man-made. If you find the real reason for the tunnel please share.
There is also some great hiking past the waterfall. I will post more about this in the future. It was one of our favorite places to go and hunt for Chanterelle mushrooms.
