2-Day Carlsbad Caverns National Park Itinerary
Descend into North America's largest cave chamber and watch 400,000 bats take flight.
Carlsbad Caverns sprawls beneath the Chihuahuan Desert, a 46,766-acre park anchored by an underground wonder that Will Rogers called 'The Grand Canyon with a roof over it.'
- 8.2 Acres (Big Room)
- 750 ft Depth underground
- 120+ Known caves
- 400K Brazilian free-tail bats
Day 1: Natural Entrance & Bat Flight
Stay: Stay in Carlsbad, NM, 30 minutes from the park; book any major hotel chain or independent lodge.
The Natural Entrance descent into the Big Room sets the trip's arc—a dramatic plunge into North America's largest accessible cave chamber followed by evening wildlife spectacle.
- Start with a hike down the Natural Entrance Trail, a steep 1.25-mile round-trip descent with 750 feet of elevation loss through switchbacks into Carlsbad Cavern.
- The paved trail leads directly into the Big Room, a massive 8.2-acre chamber that dwarfs visitors with its 255-foot ceiling and formations like the Bottomless Pit and Hall of Giants.
- After exploring the cavern at your own pace (no guide required), return to ground level and arrive at the Bat Flight Amphitheater by sunset for the nightly ranger program—approximately 400,000 Brazilian free-tailed bats emerge from the cave entrance in a swirling cloud.
Day 2: Desert Trails & Rattlesnake Springs
Stay: Check out of your Carlsbad hotel or extend your stay; most visitors depart after Rattlesnake Springs.
The surface day contrasts the cave's underground immensity with the Chihuahuan Desert's stark beauty, revealing the park's full ecosystem above and below ground.
- Leave the caverns behind for the park's surface half.
- Drive to Rattlesnake Springs, a lush riparian oasis 26 miles south of the visitor center where cottonwood trees and a natural spring attract over 330 bird species year-round.
- Spend the morning bird-watching at the picnic area, then hike the Rattlesnake Canyon Trail, a steep 6-mile round-trip descent into the canyon with 670 feet of elevation gain, offering wide views of the Guadalupe Mountains and Chihuahuan Desert landscape.
Common Questions
Do I need a reservation to enter Carlsbad Cavern?
Yes. A timed entry reservation ($1 per person) is required year-round and can be booked online at recreation.gov or by calling 877-444-6777. The last cavern entrance time is 2:30 pm. Entrance tickets ($15/adult, free for ages 15 and under) are purchased separately at the visitor center upon arrival.
Can kids go in the cave?
Yes. Children under 16 enter free with a paying adult. Kids as young as 6 can attempt the Natural Entrance hike, though the steep descent (750 feet) and uneven cave floor require stamina. Taking the elevator from the visitor center down to the Big Room (and hiking only the Big Room itself) is a gentler option for younger children.
When are the bats most active?
The Bat Flight Program runs late April through October. Peak bat activity occurs July through September, when approximately 400,000 baby bats born earlier in the summer join adults for nightly hunts. Start times vary with sunset; arrive early for a good seat at the Bat Flight Amphitheater.
How cold is it underground?
Carlsbad Cavern maintains a constant 56°F year-round, regardless of outside temperature. Bring a light jacket or sweater for the cave; it will feel significantly colder than the desert surface, especially after hiking down.
Are ranger-led tours available?
Ranger-guided tours (King's Palace, Lower Cave, Hall of the White Giant) are currently suspended. Check recreation.gov or call 877-444-6777 before your trip for updates on when they resume. Self-guided Big Room and Natural Entrance trails are always available.
