I will admit that I have read the books and all the literature I can about this mountain. They all say it got its name from its sheer size. But in all honesty, I could not ever in my wildest dreams imagine how big the mountain truly is. The size of the plateau that you climb above treeline is awesome. Once you reach the saddle at 13,900 feet, take a look back and see exactly how big I am talking about.
We used the typical Mt. Massive trail that follows the Colorado trail for the first 3.3 miles. At about 0.8 miles, the trail switchbacks and starts to finally head towards the mountain. The beginning section of this trail is easy to follow and climb. The trail starts at 10,050 feet and over the first 3.3 miles only climbs to 11,250. Makes for a fast start. But don't let this mislead you, once you hit the Mt. Massive trail, a left hand turn from the Colorado Trail, the introduction is over.
Turn to the Mt. Massive trail and start climbing. This is one of the steepest sections of the trail. Climb to treeline and soak in some of the views from there. Mt Elbert is visible off to the south 
and Massive looms large in the distance. From here you can see three of Massive's summits. The one to the left barely rises above 12,500. The middle one is "South Massive" topping 14,100 and the large one on the right is the peak you are looking forward to meeting. 
From this point, it is easy to see how the route continues to the summit. It meanders up the slope in front of you and in between South Massive and the main summit to the saddle.
Continue along the easy to follow trail and continue climbing towards the saddle. After only a short distance, the saddle becomes visable and the rest of the route to the summit can be seen. Climb the trail as it goes up relentlessly to the saddle. From here, take a look back at the size of the plateau you have just climbed. The views on the other side of the saddle are truly marvelous as well.
From the saddle, follow the ridge to the north towards the summit. There are several trails along the ridge and it isn't easy to follow. My only advice is to stay on the east side of the ridge as the west side is a steep drop off. There are several false summits along the way. at least four. Once you come to the second to last, the summit can easily been seen. 
The route from here only takes ten minutes tops, but again be careful to stay on the east side. The summit is extremely small compared to the rest of the mountain, but what do you expect from a mountain of many contrasts?
