For those looking to hike but not wanting to deal with getting in to the national park there are some shorter hikes that are right near town that can lead to good locations to view the eclipse. You can get to the top of Josie’s Ridge to view the eclipse. The hike is steep and short with a lot of area at the top where you can view the eclipse as well as trails that lead off from the top. For those not looking to hike there are many parks and public areas around Jackson and Wilson but keep in mind that these areas will probably be pretty busy so the earlier you get there the better.
Truly the total eclipse will be visible anywhere in the path of totality so long as there are not any trees or buildings in the way. The sun will be about 50 degrees up from level ground in the south east part of the sky here in Jackson. You can use a program such as Stellarium to see exactly where the Sun will be in the sky during totality by setting the location to exactly where you will be.
