Common questions

Big Bend month by month: notes from the park service

• January: January sits in the middle of Big Bend's high season. Once the New Year's crowd leaves, the park still counts the month inside the November-to-April run when the Chisos Mountains Lodge and all developed campgrounds fill every night, and holiday weekends such as Martin Luther King Jr.
• February: February at Big Bend is inside the park's main visitor season (October through April), and the park service says the Chisos Mountains Lodge and all developed campgrounds fill every night from November to April. There are no first-come sites to fall back on, so a February camping trip needs a recreation.gov reservation, bookable up to six months ahead.
• March: March is spring break at Big Bend, and the park service names spring break among its very busiest periods, on top of a November-to-April stretch when the Chisos Mountains Lodge and every developed campground are full every night. Reserve your campsite on recreation.gov (up to six months out), because there are no first-come sites, and expect one-in, one-out traffic control at the Chisos Basin, Lost Mine Trail and Hot Springs lots on the busiest days.
• April: April is the last month of Big Bend's main season, which the park service puts at October through April. Through April the Chisos Mountains Lodge and all developed campgrounds still fill every night, and any holiday weekend draws extra visitors, so book a campsite or room before you arrive rather than hoping for a spot.
• May: May is when Big Bend turns hot. The park service says that from May through September temperatures over most of the park pass 100°F by late morning and keep climbing through the day, and that direct sun runs 15 to 20 degrees hotter than the shade readings.
• June: June at Big Bend calls for heat planning. The park service urges special caution for every summer hiker, and says unprepared hikers get seriously ill, hurt or die there each year.
• July: In July, Big Bend is a park for mornings. By late morning most of it is above 100°F, the park service warns, so plan any hike for first light and finish by noon.
• August: August is deep in Big Bend's hot season, which the park service describes as scorching, with outdoor recreation uncomfortable and unsafe. Many services are reduced in summer compared with winter, when five visitor centers are open and ranger programs run more often.
• September: September is still summer heat at Big Bend: the park service counts it in the May-through-September stretch when most of the park tops 100°F by late morning. The comfortable season it recommends starts in late fall and runs through early spring.
• October: October is when Big Bend's main season opens: the park service puts its primary visitor season at October through April. The overnight squeeze that defines winter here has not fully set in yet, since the park says the Chisos Mountains Lodge and every developed campground fill every night from November on.
• November: November is the month Big Bend starts selling out. From November through April the park service says the Chisos Mountains Lodge and all developed campgrounds are full every night, and Thanksgiving week is one of its named busiest periods.
• December: December splits in two at Big Bend. The weeks before the holidays are part of the full-every-night stretch the park service describes for November through April, and then Christmas to New Year's is one of the park's busiest periods of the year.
