Fort Davis is located at the intersection of Texas highways 17 and 118, approximately 20 miles north of Marfa and approximately 24 miles north of Alpine. To get to Fort Davis from US 190 (to the south) follow either Texas 118 north from Alpine or Texas 17 north from Marfa. To get there from I-10 (to the north) take the Texas 17 South exit at Balmorhea, following it approximately 32 miles, through Toyahvale and on south to Fort Davis.
Fort Davis National Historic Site, on the north side of town, 432 426 3224. The fort was constructed in 1854 to protect the stagecoach service on the newly opened San Antonio-El Paso road from Apache and Comanche attacks.
The McDonald Observatory is atop Mt. Locke, 16 miles west on Texas Highway 118. By day, visitors can tour the telescopes and the planetarium ($8 adult, $7 children), which are owned by the University of Texas. The real attraction, though, are the Star Parties ($10 adult, $8 children) after dusk on Tuesday, Friday and Saturday. (Nov-Mar: 7:30PM, Apr-Aug: 9:30PM, Sep-Oct: 9PM) Two of the observatory's more powerful telescopes - as well as several smaller ones - are set up outside for visitors to catch a startlingly clear glimpse of star clusters, distant galaxies and even a member or two of this solar system. The altitude and the remote location ensures that light pollution is kept to a minimum, and enthusiastic guides are on hand to explain exactly what the scopes are showing. Bring a warm jacket regardless of the season, as the temperature drops rather steeply at night.
Davis Mountains State Park lies on the other side of Fort Davis Park, connected to it by four miles of trails. Entrance off Texas Highway 118 just west of town.
