It starts on a slight incline and then gets gradually steeper. Trail is pretty smooth. After a tough climb, you get a downhill followed by a field. Then there's a fork in the road. If you actually want to get to the lake, take a left at the fork. Climb some more. View the beautiful Tetons on your left. You'll come to a clearing at the top. If you look down to the left, the lake is between the trees down the steep decline singletrack. Don't ride right into the lake. It's freezing, and does a quick dropoff.
From Rexburg, take State Hwy 20 north to State Hwy 33. 20+ miles out you'll see a sign for Elk Ranch. Turn right there. Follow the road for 5 miles. You'll get to a gate in an old ranch fence. There will be a sign for Packsaddle Lake there.
