Best Route

What they said and additionally from Galveston take SH146 to Dayton until it dead ends into US90...go right then a quick left at the McDonalds...take this to Cleveland and US59.

I would take US59 to I-30 in Texarkana and then follow the directions from the park's site: From Texarkana - Go east on I-30 for 30 miles and take Exit #30 at Hope. Take U.S. 278 north and go 27 miles to Nashville. From Nashville, take Ark. 27 north and go 13 miles to Murfreesboro. From the courthouse square in downtown Murfreesboro (North Washington Avenue), travel two miles southeast on Ark. 301 to the park.
