Big Bend National Park being in the middle of nowhere, you might wonder where you can go grocery shopping! Inside the park, there are three small general stores, one at Chisos Basin, one at Rio Grande Village, and one near Santa Elena Canyon. The towns around the park have small grocery stores: Study Butte, Terlingua (West of the park), Marathon (North of the park). For a real supermarket, you have to go to Alpine, 100 miles (150 km) Northwest of the park.
What to pay: In the park, certainly overpriced!
The Visitor Centers of the park have books, post-cards and souvenirs on Big Bend. They are located at Persimmon Gap, Panther Junction and Chisos Basin. For souvenirs and art beyond National Park stuffs, it is worth driving to Terlingua/Study Butte, Alpine or Marathon. In the latter, I went to this delicious shop that sells latino crafts called Artesania's. It is located on the main road through Marathon, I90.
There are three small stores within the National park. These stores are located at the Rio Grand Village, the Chisos Basin, and in the historic La Harmonia area at Castolon. Here you can purchase some basic camping supplies and a few groceries.
The Chisos Basin Lodge also has a Gift Shop which features various items made by local artists, as well as clothing, jewelry, postcards, and Big Bend souvenirs.
What to buy: Some of the items you can purchase include a small variety of canned and boxed foods, snack foods, bottled water, beer, pop, ice cream, and postcards.
