The Stage 1 container IS at the posted coordinates. Instructions and everything you need are inside although you might want a pen and paper to make notes or something.
There are several available routes. The easier but longer route starts at the Mt Cutler trailhead in Cheyenne Canyon. You can take that trail to the Mt Muscoco trail (waypoints provided) which will take you close to Stage 1. That route is about 3.5 miles round trip and the trail gets fairly steep in places. I recommend the shorter, even steeper route. It starts a little further up the canyon (see waypoints). I think I ended up making 11 total trips to place this cache. The final time being with The Lady Gypsy, for the second time that day, after a dinner party, in her skirt, in the dark, on a moonless night, by the light of my old school flip phone. There are some cliffs nearby so I don't recommend this cache for small children. I doubt the field puzzle should take as long as an hour but if you like the puzzle there are more you could do just for fun. I'd count on at least a 3 hour trip. If the weather's nice, it's a gorgeous spot for a picnic. Enjoy :-)
