Minuteman Missile National Historic Site

Overview

During the Cold War, there were 150 intercontinental ballistic missile (ICBM) silos in South Dakota.  Start your visit at the thought-provoking museum in the National Park Service (NPS) visitor center on Interstate 90, located at Exit 131 (the east entrance into Badlands National Park).  It can be hard to get onto a tour of the Delta-01 launch control facility that same day without reservations, but you can always stop at the Delta-09 missile silo at Exit 116.

Highlights

Museum, Delta-09 missile silo, guided tours of Delta-01 launch control facility

Must-Do Activity

Guided tours of the Delta-01 launch control facility have very limited space and a nominal fee, but are no longer solely first-come, first served thanks to an online reservation system.  Guided tours are also available of the Minuteman II training silo at Ellsworth Air Force Base down the road on Interstate 90 at Exit 67, which is home of the free South Dakota Air and Space Museum (that is definitely worth a stop).

Best Trail

Located off Interstate 90 Exit 116, you can walk around the Delta-09 missile silo, which has interpretive signs around a deactivated Minuteman II ICBM.

Stop to read the quote by the front door to the NPS visitor center.  It is a sobering reminder of the brutal logic behind “nuclear deterrence” and “Mutually Assured Destruction (MAD).”

Peak Season

Summer and the September weekend of the Custer State Park bison roundup.

Bent’s Old Fort National Historic Site

Overview

Bent’s Old Fort on the Arkansas River on the prairie of eastern Colorado has been painstakingly reconstructed to its appearance of 1845.  It was originally built in 1833, long before Fort Larned and Fort Union announced the U.S. military presence on the 1,200-mile-long Santa Fe Trail.  Historical reenactors are happy to talk to visitors about the site and its famous inhabitants and visitors.

Highlights

Reconstructed fort, film, living history

Must-Do Activity

The “old fort” was originally built with the financial backing of the two Bent brothers from St. Louis and a Taos trader named Ceran St. Vrain.  It was a huge success, bringing a period of peace to warring tribes on the Great Plains, particularly after William Bent married a Cheyenne woman.  Things changed once Texas was annexed by the U.S. in 1845 and the military moved in, spurring a move to Bent’s New Fort 38 miles downstream.  

Best Trail

The parking lot is less than a half-mile walk from the fort, yet we found that approaching on foot added to the historic experience, as did speaking with the reenactors roaming inside.  Closer handicap parking is available.  Another trail leads to the banks of the Arkansas River on a 1.75-mile loop.

Instagram-worthy Photo

In 1975, the adobe fort was reconstructed on its original foundation in southeast Colorado based on drawings by Lieutenant James Abert, a topographical engineer stationed here in 1845 and 1846. 

Peak Season

Summer, but watch for afternoon thunderstorms.

Hours

Road Conditions

All roads paved, although they can be closed due to spring floods on the Arkansas River.

Camping

There are private campgrounds in nearby La Junta, Colorado and a public one run by the Corps of Engineers at John Martin Reservoir (27 miles east on Highway 50).

Oregon Caves National Monument and Preserve

Overview

In the remote southwest corner of Oregon, this marble cave system has been federally protected since 1909.  The Civilian Conservation Corps (CCC) worked extensively on the trail system and chateau-style lodge in the 1930s.  In 2014, an additional 4,000 acres were added to preserve the surrounding old-growth forests, the most biodiverse conifer-dominated ecosystem in the world.

Highlights

Cave tours, Oregon Caves Chateau, Big Tree, Mt. Elijah

Must-Do Activity

The Oregon Caves Chateau is currently closed for renovation, but is scheduled to reopen to guests in 2021.  That means the main reason to visit is to take a tour inside the cave, but bundle up because it remains a brisk 44°F year round.  The standard tour is 90 minutes, has a height requirement of 42 inches, and includes 500 stairs, which can be strenuous at 4,000 feet in elevation.  In the summer, a candlelight tour, off-trail “wild caving” tour, and family-friendly tour (for those with small children) are also offered.

Best Trail

The Bigelow Lakes-Mt. Elijah Loop Trail covers 9.2 miles and gains 2,390 feet in elevation while providing the best views of the surrounding mountains.  At a minimum, you should try to hike the Big Tree Trail 2.6 miles roundtrip to the largest diameter Douglas-fir tree in Oregon.

After your cave tour exits far uphill from its entrance, continue on the Cliff Nature Trail for a great view of the lush Siskiyou Mountains.

Peak Season

Summer, since cave tours are only offered from late March through November.

Hours

https://www.nps.gov/orca/planyourvisit/hours.htm

Fees

There is no entrance fee to the park, but there is a charge for all cave tours (which can be reserved in advance).

Road Conditions

The paved entry road is winding and climbs steeply.  Most surrounding Forest Service roads are unpaved and one climbs to provide access near the top of the Bigelow Lakes-Mt. Elijah Loop Trail.

Camping

Cave Creek Campground is located 4 miles from the cave entrance.  Trailers are only permitted at Grayback Campground, further down the hill.

Carlsbad Caverns National Park

Overview

Carlsbad Caverns in southeastern New Mexico is the most spectacular cave in the United States (and #1 on our Top 10 List).  Exploring the Big Room at your own pace is a great option, but you can add to your experience with guided tours of off-limits sections.  The King’s Palace Tour is short but scenic; and Left Hand Tunnel was historically used for movies.  Lower Cave Tour requires the use of ropes and ladders to access unlit portions of the cave.  Slaughter Canyon Cave tour requires an extra hour drive, but visits some astonishing formations.  “Wild caving” tours include Spider Cave and the Hall of the White Giant. 

Highlights

Big Room, Walnut Canyon Desert Drive, Rattlesnake Springs Picnic Area, Bat Flight Program

Must-Do Activity

To enjoy the evening Bat Flight Program (where cameras are prohibited) you must come during the warmer months.  Brazilian free-tailed bats migrate to the cave from the south and around sunset exit from the Natural Entrance in clockwise circling swarms.  You will swear there are like a “Brazilian” of them, but the actual number is closer to 500,000.  For an experience you will hear more than see, come back before sunrise as the bats zip by your head down into the cave for their day’s rest.

Best Trail

For your first visit, we recommend taking the self-guided trail from the Natural Entrance down a steep, paved passage into the heart of the cave, since you can always ride the elevators back up to the surface.  After being surrounded by the natural cave formations, it was a bit jarring to come upon a modern restroom and cafeteria 775 feet underground. 

Instagram-worthy Photo

Nothing can prepare you for the immensity of the Big Room, which is big enough to fit eight football fields with a ceiling that rises up to 255 feet.  It defies belief that this cavity could have formed naturally.  Perhaps the best part of this section of cave is that you can take as much time as you like admiring the formations.  For the best photographs, we recommend using a tripod.

Peak Season

Summer, though it can be hot outside the 56°F cave.

Hours

https://www.nps.gov/cave/planyourvisit/hours.htm

Fees

No entrance fee, but there is a charge for each guided cave tour.

Road Conditions

Main entrance road is paved, but Walnut Canyon Desert Drive and much of the route to Slaughter Canyon Cave are not.

Camping

There are no campgrounds within the park, but there is a private campground near the park entrance in Whites City, New Mexico.  Just down the highway in Texas, the National Park Service offers camping at Pine Springs within Guadalupe Mountains National Park.  Free permits are required for backcountry camping, with Rattlesnake Canyon off Walnut Canyon Desert Drive being a popular destination.

This design we created to celebrate Carlsbad Caverns National Park is available on a variety of products at Cafe Press and Amazon.
