It is in the Giant Forest section, which is the main sequoia attraction in the park. The trail starts from the parking lot for the General Sherman tree. The President tree and the McKinley tree and the Chief Sequoia tree are all on the trail. The Senate Group is also impressive--fewer trees, larger trees, but not quite the "cathedral effect" of the House group. I am not sure, but I think the trees in the House Group are just about as tall as any of the sequoias. At one time they were so advertised, but so many measurements have had to be revised since those days.
If you are on this trail, and have a small trail map of the area, don't miss Crescent Meadow, the trail to which connects with the Congress Grove trail. John Muir called Crescent Meadow the "jewel of the Sierra." Or did he use the term "gem" instead of "jewel." Doesn't matter--an absolutely stunning place surrounded by large sequoias. If you visit this place, don't "rush," but let things "soak in." I would pack a lunch, and spend a whole day on these two trails, picking nice spots to sit and let things "come to you," so to speak. This trail is one of the most popular trails in the Park, but don't let that bother you. If you want a bit of solitude, let the people pass, wait, and you can have it.
There is also a separate parking lot for Crescent Meadow, and the trail to it from that lot is very short. The famous Log Meadow is right next to Crescent Meadow, and Tharp had his log house there, which he used when he grazed his cattle there in the summer. But if you have time, hike through from the Congress Grove trail. Fewer people do that, and you will see much more beautiful forest.
And a short climb up Morro rock is nice--also right in the same area. Grand view!
And for a more "mountain hike," you can hike to Bear Paw Meadow. I did that in early spring one time, before anything there was open, and camped for the night. When we arrived, we were lost in fog, and the snow was so deep, we couldn't find the trail easily. In the end, we camped on the little porch of a pavilion there, lost in the fog, above kaweah Canyon. At about 2 a.m. all three of us woke up in the moonlight. The fog had settled down into the valley/canyon, like some grand sea, and the high sierra loomed over us, all shimmering white with snow in the moonlight. Maybe the most beautiful and spectacular scene I have ever seen. And we could hear rising up from below the rushing water from streams and waterfalls full from the spring melting.
But in the "season," this area is likely to be crowded, so....
Sequoia park is more than the groves of grand, unbelievable trees!
Well, I'm nothing if I don't digress.
