I hope some of this is helpful for you.
Go West on Spain Road off Tramway Blvd. till it ends at a T intersection. Turn right, go about 100 ft. and the TH parking is on your left. Wonderful trails right out of the parking area. I’m told the more difficult trails are accessed by driving down Tramway toward I-40, and then West to the TH’s on either Menaul or Copper. The bike shop I used was Northeast Cyclery at 8305 Menaul NE. These guys there were friendly and very helpful, had trail maps, etc.
If you like New Mexican cuisine the restaurant at the base of the Tramway lift is better than the one on the summit, in my opinion. For hotter spices, Sadies was good but it’s farther away from your Sandia riding trails.
