Big Bend RV Resort is only a few minutes from the gate, but then its along drive to anywhere in the park. We stayed at RGV this past winter. The only draw back to using the hookup sites is they are close together. Since we have a generator, we stay in the no hookup section. In late January, the hookup section was full, maybe a 1/3 in the dry section. We would have liked a spend a couple of nights in the Basin but our trailer is too long to get up there. Take your passport and take a day trip across the river. We also left there to go to Ft Davis State Park and the McDonald Observatory. A word of caution, while it might be warm in the state park, there could be snow up at the observatory (we about froze but was worth it). Take warm clothes.
