Sweetwater-OfficeRide-19DEC01-02-MikeJD-2.JPG (91115 bytes)Sweetwater-OfficeRide-19DEC01-01-MikeJD-1.JPG (91973 bytes)This was our first time out at Sweetwater reservoir so this was going to be an exploratory trip.   My cohorts in fat tire mayhem for this trip were Mike Roach and John Dannecker Mike on Right, John on Left).  The parking lot is located at Point A.  We brought a couple of tall boys for some post ride refreshments but were short a cooler and it was getting pretty toasty outside.  Mike decided to bury the our refreshments in the shade and see if they would stay cold.  So after Mike was done playing digger dog, we set out from the parking lot west Sweetwater-OfficeRide-19DEC01-03.JPG (65090 bytes)along a dirt road and up a small rise towards the dam.  At around Point B. (picture to the left) we decided to try the trail in the other direction.  Once back by the parking lot we head out to the east and over our first set of horse gates.   Here is were we found some confusing.  The parks trail map clearly shows that the trails are open to bikers, hikers, and horses.  Yet right there at the gate there was a sign saying that the trial was for a hiker and horse trail.  It did not say NO bikes allowed, but it sure did not mention them.  Of course the devil is in the details.  The small print on the sign said that it was place there by the a local equestrian club, which means the sign is a cheap trick attempt to keep mountain bikers off of open trails.  (At several points along the ride we ran into these signs, just ignore them.)   Well once we figured this out we rolled fairly flat terrain with a view of the reservoir to our left.  At Point C, we came to our first hill.  It had a short series of switchbacks in them that were easily rideable if you have done any switchback before.   Below are some pictures of this area.

Sweetwater-OfficeRide-19DEC01-07-TopofHill.JPG (50434 bytes)Sweetwater-OfficeRide-19DEC01-08.JPG (57574 bytes)After the switchback the terrain became a little hillier.  As we approached Point D we had to climb a short but steep and loose hill that tested your ability to handle going from little to max exertion in an instant.  Once a Point D, we had nice view as well as a picnic table to chill on for a minute.  The elevation at this point is 471 feet with the reservoir below at 241 feet.  San Miguel Mountain was 2.44 miles off to the east.  There is fire/access road that goes up to it's peak at 2,568 we means it would be a good workout.  We did not do that this trip but it is on the To-Do list.    

 

Sweetwater-OfficeRide-19DEC01-09-SweetSingleTrack.JPG (102029 bytes)After we all regrouped, we pressed on into a sweet section of rolling of singletrack (Point E) .  Nothing technical to speak of,  just comfortable rolling.  

 

Sweetwater-OfficeRide-19DEC01-10-JDcomingDownTheHill.JPG (119838 bytes)After about a mile the trail rolled into a flat area and hung a left turn at Point F.  Shortly after this point, we had to go through another horse gate and there was another bogus sign posted there.  After passing through the gate, you are on dirt road that goes off to the right.  A little further down the road you see another dirt road going off to the right.  This is the road that should go up to the peak of San Miguel.  Once again we did not do that ride.  The road dwindled back into single track.

At the steel bridge most folks turn around and head back the way they came.

Ohh, ... The tall boys were still cold when Mike dug them up at the end of the ride!

December 2004 Update

 

I have updated the map with some additional trails I rode on my latest ride there.  They are in purple on the map.   There are certainly more trails here than I have shown so feel free to explore.   If you go all the way to the bridge, I would recommend that on your way back at Point F,  hang a left at a Y split in the singletrack and work your way up to the saddle.   This will bring you up to a fireroad.  Follow in down to a small pond where you hook up with some singletrack that works its way back towards Point D.  At your next intersection, take the "high trail" to your left for some nice contour riding that takes you gradually up to a ridgeline.   At the top look for a singletrack bearing off to the right.  Take it for some wonderfully ridgetop ride and gradually descent back to Point C.

Here are some pictures from along the route I just described
