Five friends and I traveled to Big Bend National Park in April 2017. Big Bend has the least light pollution of any National Park, and on a clear night, visitors can see the Milky Way galaxy and over 2000 stars. We saw the Milky Way during our trip in the southern sky.
April is a good time to visit before the temperatures become hot. The temperature at the park headquarters averages about 84 deg F, but the temperatures where we stayed at the Rio Grande Village reach 5-10 degress warmer, and we saw highs in the 90’s during the day. Since most of our hiking was at Chisos Basin in the mountains, temperatures were 10-20 degrees cooler. The dry desert environment can have 30 degree temperature swings between night and day in April.
