Big ThicketNational Preserve - Texas |
Big Thicket is the name of a heavily forested area in Southeast Texas, United States. Several attempts to provide boundaries have been made ranging from only a 10 to 15 mile section of Hardin County to an area encompassing over 29 counties and over 3,350,000 acres. While no exact boundaries exist, the area occupies much of Hardin, Liberty, Tyler, San Jacinto, and Polk Counties and is roughly bounded by the San Jacinto River, Neches River, and Pine Island Bayou. To the north, it blends into the larger Piney Woods terrestrial ecoregion of which it is a part. It has historically been the most dense forest region in what is now Texas, though logging in the 19th and 20th centuries dramatically reduced the forest concentration.

Big Thicket is the name of a heavily forested area in Southeast Texas, United States. Several attempts to provide boundaries have been made ranging from only a 10 to 15 mile section of Hardin County to an area encompassing over 29 counties and over 3,350,000 acres. While no exact boundaries exist, the area occupies much of Hardin, Liberty, Tyler, San Jacinto, and Polk Counties and is roughly bounded by the San Jacinto River, Neches River, and Pine Island Bayou. To the north, it blends into the larger Piney Woods terrestrial ecoregion of which it is a part. It has historically been the most dense forest region in what is now Texas, though logging in the 19th and 20th centuries dramatically reduced the forest concentration.
Life of all types abounds in the Big Thicket. This national preserve protects the incredible diversity of life found where multiple habitats meet in southeast Texas. Hiking trails and waterways meander through nine different ecosystems, from longleaf pine forests to cypress-lined bayous. It is a place of discovery, a place to wander and explore, a place to marvel at the richness of nature.
The main corridor through the Big Thicket is US Hwy 69/287 between Beaumont and Woodville. Many smaller roads and highways branch off of the main corridor to reach trailheads and scenic areas. The visitor center is located at the intersection of US 69/287 and FM 420, about 7 miles north of Kountze and 30 miles north of Beaumont.
Big Thicket Visitor Center
Start your trip here! Get free maps and information, meet a park ranger, and learn about the Big Thicket's plants, animals, and history. Staying awhile? Watch a short film in the theater and browse the bookstore. Outside, enjoy a shaded picnic and go for a short hike on the Longleaf Pine Trail.
The visitor center is located approximately 30 miles north of Beaumont, and 7 miles north of Kountze, at the intersection of US 69/287 and FM 420. The visitor center entrance is on FM 420.
No developed campgrounds in the preserve
There are no developed campgrounds or backcountry campsites within Big Thicket National Preserve. The preserve issues free camping permits for backpackers. Boaters may get camping permits to camp on sandbars.
There are several private and state park camping facilities in the local area.

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

A Vast and Varied Biological Preserve
Big Thicket once sprawled
over 3.5 million acres of
southeast Texas. Today Big
Thicket National Preserve
protects 15 remnant areas—
108,208 acres—with nine
habitats. Multiple habitats,
and the fact that species
from other regions converge
to co-exist here, account for
this biological preserve's
remarkable diversity of
animals and plants.
In Big Thicket you won't find
a high peak, deep gorge, or
other dramatic feature. You
will find instead a surprising
lushness and density of

Beech Creek Unit
The Beech Creek
Unit
The Beech Creek Unit consists of 4,925 acres. It has rolling terrain with numerous
spring-fed streams and a beech-magnolia-loblolly forest community. Hunting is
allowed in parts of this unit with a permit during the fall season; check with park staff
about the exact dates of the hunting season each year. However, the hunting area is
north of the Beech Woods Trail, so the trail is open year round.
Hiking the Trail
The Beech Woods Trail makes a 1.0-mile loop through a hardwood forest. It leaves
the dirt road 0.3 miles north of the parking area. Hikers may also follow the dirt road,
which extends for 6 miles through the Beech Creek Unit.
Vegetation
American beeches, southern magnolias, loblolly pines, and American holly are the
most common trees in the Beech Creek Unit. In the spring, flowering dogwood,
redbud, azalea, and Elliott’s blueberry color the mid-story. In the summer, look for
the crane-fly orchid, whorled pogonia, and the beechdrops, three species which grow
only under the shade of beech trees. White oaks, sugar maple, and strawberry bush
provide a vivid contrast to the evergreen pines and magnolias in the fall. The winter
landscape is marked by evergreen Christmas fern, yellow blooming witch hazel, and
the lichen-mottled trunks of beech trees.
Hunting Season
While the Beech Woods Trail is not within the hunting area boundary, hunting is
allowed in most of the Beech Creek Unit during part of the year. All visitors are
advised to wear at least 400 square inches of Hunter Orange or International Orange
when exploring this unit beyond the designated hiking trail during hunting season.
Backpacking is not allowed in this unit during hunting season.
Contact the Big Thicket National Preserve visitor center at 409-951-6700 for more
information on hunting season.
Know Before You Go
All plants, animals, and other natural and cultural resources are protected in the
preserve. It is illegal to collect, harm, or kill anything, including snakes.
Wheeled vehicles are not allowed on this trail.
Backpacking is allowed in the Beech Creek Unit during non-hunting season. A
camping permit is required; these are available free of charge at the visitor center. Call
the visitor center at 409-951-6700 for more information.

Trails of the Big Sandy Creek Unit
The Big Sandy Creek Unit is located in the northwest corner of the preserve, in Polk County, Texas. This diverse unit
of nearly 14,000 acres allows hikers to experience at upland pine forests, beech-magnolia-loblolly pine woodlands, a
cypress bog, and floodplain plant communities. Three developed trails prvoide easy access into the Big Thicket, while
more adventurous explorers are welcome to travel off-trail into the wilderness.
Woodlands
Trail
This 5.4 mile trail begins in an old pine plantation, planted around 1963 after the area was logged. This
mature forest community skirts Collins Pond, a man-made body of water found just a short stroll from
the trail entrance.
The western portion of the trail follows the top of a slope, where beech, magnolia and loblolly pine trees
are common. The eastern portion of the trail winds through the floodpain along Big Sandy Creek. The
forest canopy becomes more dense in this area, creating more shade and less nutrients for grasses and
shrubs. Common floodplain trees here are sweet gum, water oak, tupelo and basket oak, with an
understory of hornbeam and holly.
Fishing is permitted in Collins
Pond and all the waterways in
the preserve, with a valid
Texas State Fishing License.
Backpacking and primitive
camping are permitted near the
Woodlands Trail year-round
with a free camping permit. In
other parts of the Big Sandy
Creek Unit, camping is
permitted only during nonhunting seasons. Inquire with
a park ranger for camping
details.
Hiking Tips
• Let someone know where
you are going and when to
expect you back.
• Drink plenty of water.
Always bring more water
than you think you might
need.
• Bring insect repellent, and
wear sun screen.
• Watch out for snakes.
Look for lettered posts
along the trail for
assistance navigating
this trail.

More information is avalaible
at www.nps.gov/bith and at
the preserve visitor center,
6102 FM 420, Kountze, Tx.
This 1.5 mile trail offers a shady retreat from the heat. Enjoy some solitude on this short loop through a
floodplain along Big Sandy Creek. Abundant cypress, magnolias, hornbeam, moss, and ferns line this
easy walk through the woods.
A map of the Beaver Slide Trail is located on the back side of this brochure.
Be Aware!
Hunting for deer, hog, rabbit and other Texas game species is permitted in parts of this unit with a free
hunting permit. Hunting season is typically in the fall and winter months. All the hiking trails are open
year-around. We recommend all visitors wear hunter orange or international orange when exploring the
Big Sandy Trail during hunting season. Ask a park ranger for more information about hunting season.
Big Sandy
Trail
The Big Sandy Trail is 9 miles one-way, 18 miles round-trip. It follows a series of abandoned logging
roads through several distinct plant communities. This multi-use trail is open to hikers, backpackers,
bicyclists, and horseback riding.
Big Sandy Trail
Bicycle Use
Bicycle riding is permitted on all park roads, parking areas, and on the Big Sandy Trail. This is the
only trail in the preserve that permits bike riding. Off-trail riding is prohibited, as is the construction of
jumps or other features. The use of helmets is highly encouraged.
Horseback
Riding
Visitors are permitted to bring their own horses and ride on the Big Sandy Trail. This is the only trail
in the preserve that permits horseback riding. Below are a few special considerations.
•
•
•
•
Off-trail horesback riding is prohibited. Horses must stay on trail.
Horses must be kept under physical control at all times and may not be left unattended. Tying
horses directly to trees is prohibited. Hitch rails, when available, must be used. In the absence
of hitch rails, horses must be tied to a line strung between trees in such a manner that stock
cannot damage tree trunks, tree roots, or other vegetation.
Grazing is not permitted. Hay is not permitted in the backcountry.
Horse manure that has accumulated from tethering must be scattered.

Plants that Eat Insects!
Carnivorous Plants: Four of the five types of insect-eating plants in the US are found in the Big Thicket. Two short
nature trails highlight the locations of sundews and pitcher plants in the the preserve. Butterworts and bladderworts
have more specialized habitat needs and are much harder to find.
Sundew Trail
This 1-mile loop trail is a great place to see birds,
wildflowers, and the bright red sundew plant.
The fully accessible 0.3 mile inner loop winds
past a small pitcher plant bog and through a
wooded savannah that has abundant summer
wildflowers. The outer loop of this trail passes
through a longleaf pine savannah. Look for the
dime-sized red rosettes of the sundew plant along
boardwalks and in other disturbed areas along the
trail.
This area is closely managed by the preserve’s
fire management team. Prescribed burns every 2
to 3 years play an important role in maintaining a
healthy longleaf pine ecosystem. A detailed
interpretive trail guide is available for purchase
at the preserve visitor center.
Pitcher Plant
Trail
This 1-mile loop trail leads visitors through a
longleaf pine forest into the largest pitcher plant
bog in the preserve. Follow the paved trail and
elevated boardwalk into the wetland savannah to
see hundreds of these funnel-shaped plants. Lured
by the plant’s nector glands, insects fall into the
pitcher, where digestive fluids and bacteria break
down their bodies for absorption.
The first quarter mile of this trail, from the
parking lot to the pitcher plant bog, is fully
accessble. The trail continues past the bog into a
mixed hardwood/pine forest. It intersects with the
Turkey Creek Trail at two different locations, so
be sure to follow the signs carefully.
Fun Facts about
Carnivorous Plants
•
While the soil here supports
lush plant growth, it is
actually very poor in nutrients,
particularly nitrogen. Insects
provide the missing nutrients
these plants need.
•
Carnivorous plants are
capable of photosynthesis but
obtain most of their nutrients
from insects.
•
Some species of spiders,
praying mantis, and frogs hunt
insects at pitcher plants and
eat them before they fall in.
•
You might think that these
plants would help to control
mosquito populations, but just
the opposite is sometimes
true. The larvae of some
species of mosquitoes are
impervious to the plants’
digestive juices. The adult
mosquito lays her eggs in the
fluid inside the pitcher plant,
where the larvae develop and
feed on trapped insects.
•
The most well-known
carnivorous plants, the Venus
flytrap, does not grow in the
Big Thicket. It is native only
to North and South Carolina.
