At the Mariposa Grove parking lot you can pick up a trail guide for 50 cents. It has a small map of the area as well as a brief history of the grove. I brought along Michael C. White’s book, “Snowshoe Trails of Yosemite” but I ended up using the trail guide, mainly because of portability.
This time of year you can walk the paved Tram route or stick to the foot path. I did a little of both.
