The trail to Bunsen Peak is in Yellowstone National Park. The trail is close to the highway, so you won't be able to escape the noise from the road until you've made it to the top.
The trek to Bunsen Peak is an easy one (the last two miles re the hardest part). Things get steep, but there are switchbacks that make it a little easier.
There are communication towers at the top of the trail, so you should have cell service the whole time.
From the top, you'll be able to see the Tetons if you look south, and if you look north, you'll see the Mammoth area.
Come with plenty of water because there aren't any fill-up spots. There's also minimal tree cover from the sun so bring layers or sunscreen.
