From the parking lot follow the gravel road beyond the gates towards the Trexler Environmental Center, the contemporary building directly ahead. Make note of the red-blazed Trexler Border Trail as it crosses over - this is where the hike will start. All of the trails in the preserve are marked with colored triangles, sometimes double triangles to distinguish different trails using the same color. Many intersections have numbered kiosks that will be referred to throughout this hike.
At the Environmental Center, continue up the ramp that leads directly to a viewing deck on the roof of Lehigh County’s first Leadership in Energy and Environmental Design (LEED) certified building. Everything is “green” – the vegetative roof with solar panels, recycled concrete cinder blocks, toilets that use rainwater to flush and tilted bird-friendly windows. Look around at the breathtaking scenery – it’s a preview of where this hike will be taking you.
Return along the gravel road to the Trexler Border Trail, marked with red triangles, and turn right. Pass the double teal trail, which is the Observation Trail that loops around the Environmental Center. The red trail descends into the ravine. At the bottom, turn right on the teal-blazed Nature Trail, marked with single teal triangles versus the double teal triangles of the Observation Trail.
After .4 mile cross a paved park road, rock hop over a small creek and continue following the teal trail as it veers left along the creek. Another tenth of a mile brings you to Jordan Creek. To the left the paved park road goes under water right through Jordan Creek. This is called “The Ford” where for 50 years cars have forded Jordan Creek to get through the park. Continue to the right where you will see a pedestrian bridge for use in crossing the creek without getting wet. The Lehigh Valley Zoo, where an entrance fee applies, is reach by taking that bridge. But before the bridge and just after kiosk #15, turn right on the double blue-blazed Elk Viewing Trail.
This footpath will ascend up to and along a ridge. Watch to your right for a herd of elk in their habitat that runs along this section. Arrive at a wooden fence beyond which is a paved park road. Continue left before the fence to a picnic table and bench for a view of the sprawling valley with the Lehigh Valley Zoo directly below. You may hear some zoo resident vocalizations drifting up, animal sounds that aren’t normally heard on a hike.
Continue on the double blue trail, passing by kiosk #13, as the trail reenters the woods to the left then passes a new pink-blazed trail on the right not yet shown on the map. The double blue trail will now descend, steeply at times, flowing into a switchback that more gently brings you down to Jordan Creek with Schlichers Covered Bridge on the right. This bridge, built in 1882, is now closed to vehicular traffic due to its decaying state. Take a good look while you can because in 2013 the covered bridge is scheduled to be replaced with a safer replica so traffic can flow through again.
Turn right leaving the double blue trail and cross the paved Game Preserve Road in front of the covered bridge. Hop over the metal guardrail then rock hop over the feeder creek (waterproof hiking shoes will help keep your feet dry here as stepping stones may be an inch under water) and climb up the short but steep embankment to kiosk #9 at the white-blazed Fireman’s Trail, a trail built by area firefighters as a forest-fire training exercise. Turn left and follow the white-blazed trail as it ascends steadily opening up to more views as it climbs higher.
When the white trail ends, turn left on the orange-blazed Turkey Ridge Trail. At kiosk #3 keep left on the green-blazed Teardrop Trail and watch for open views of the Jordan Creek valley to the left. At kiosk #4, when the green trail goes both left and right, make a sharp right turn. You will be hiking through hilltop fields and meadows with views all around. Continue straight on the green trail passing by other trail intersections at kiosks number 5, 2 and 1.
The green trail ends at the red-blazed Trexler Border Trail at kiosk #7. Turn left here as you decide how you would like to proceed. To continue following this hike, turn left on the yellow-blazed Hunsicker Valley Trail, an old grassy roadbed that descends and meets up with the western side of the red-blazed Trexler Border Trail. Turn right on the red-blazed trail and as it ascends up and up to the best view yet. At the top a bench marks the spot with panoranic views to the north. On the horizon lies the Blue Mountain upon which the Appalachian Trail resides. Continuing on, the red trail loops back around to kiosk #7. There will be a couple more ups and downs during the remainder this hike so if you would rather eliminate this one but still take in the view, instead of turning left on the yellow trail as described at the beginning of this paragraph, stay on the red trail, almost level all the way to the view, then retrace back to kiosk #7.
Continue following the red-blazed trail for the rest of the hike, about 2.2 more miles, but you might want to take about a half-mile detour in search of bison along the way. Leaving kiosk #7, the red trail will cross over the paved Game Preserve Road in .65 mile, follow parallel to the road for a short while, then turn right on a paved park road between two pillars and slowly wind uphill on this road before heading back into the woods via a footpath to the left. Start watching the horizon where you might spot the black dots of bison high up on the hill. When the red trail reaches the paved park road again, turn right leaving the trail and follow the paved road, passing a trail to a group camping area on the right. You should find the bison in one of the fields in this area on either side of the park road. After visiting with the bison that will barely raise an eye at your presence, retrace your steps along the paved park road and pick up the red trail to the left of a small brown building just beyond where you left off.
There is now .7 mile of the red Border Trail left that will, for the last time, dive down into a valley and back up again towards the Environmental Center which sits on the hill up ahead. When you reach the gravel road of the Environmental Center, turn left back to the parking lot.

Whether you are going for a day hike or backpacking overnight, it is good practice to carry what we call The Hiking Essentials. These essentials will help you enjoy your outing more and will provide basic safety gear if needed. There may also be more essentials, depending on the season and your needs.
Hiking Shoes or Boots
Water - Two quarts per person is recommended in every season. Keep in mind that fluid loss is heightened in winter as well as summer. Don't put yourself in the position of having to end your hike early because you have run out of water.
Map - Know where you are and where you are going. Many of our hiking areas feature interconnecting network of trails. Use a waterproof/tear-resistant Tyvek Trail Conference map if available or enclose your map in a Ziplock plastic bag. If you have a mobile device, download Avenza’s free PDF Maps app and grab some GPS-enhanced Trail Conference maps (a backup Tyvek or paper version of the map is good to have just in case your batteries die or you don't have service). Check out some map-reading basics here.
Food - Snacks/lunch will keep you going as you burn energy walking or climbing. Nuts, seeds, and chocolate are favorites on the trail.
Sunscreen and insect repellent
Rain Gear and Extra Clothing - Rain happens. So does cold. Be prepared for changing weather. Avoid cotton--it traps water against your skin and is slow to dry. If you are wearing wet cotton and must return to your starting point, you risk getting chills that may lead to a dangerous hypothermia. Choose synthetic shirts, sweaters and/or vests and dress in layers for easy on and off.
Compass - A simple compass is all you need to orient you and your map to magnetic north.
Light - A flashlight or small, lightweight headlamp will be welcome gear if you find yourself still on the trail when darkness falls. Check the batteries before you start out and have extras in your pack.
First Aid Kit - Keep it simple, compact, and weatherproof. Know how to use the basic components.
Firestarter and Matches - In an emergency, you may need to keep yourself or someone else warm until help arrives. A firestarter (this could be as simple as leftover birthday candles that are kept inside a waterproof container) and matches (again, make sure to keep them in a waterproof container) could save a life.
Knife or Multi-tool - You may need to cut a piece of moleskin to put over a blister, repair a piece of broken equipment, or solve some other unexpected problem.
Emergency Numbers - Know the emergency numbers for the area you're going to and realize that in many locations--especially mountainous ones, your phone will not get reception.
Common Sense - Pay attention to your environment, your energy, and the condition of your companions. Has the weather turned rainy? Is daylight fading? Did you drink all your water? Did your companion fail to bring rain gear? Are you getting tired? Keep in mind that until you turn around you are (typically) only half-way to completing your hike--you must still get back to where you started from! (Exceptions are loop hikes.)
Check the weather forecast before you head out. Know the rules and regulations of the area.
The Leave No Trace Seven Principles
Plan Ahead and Prepare
- Know the regulations and special concerns for the area you'll visit.
- Prepare for extreme weather, hazards, and emergencies.
- Schedule your trip to avoid times of high use.
- Visit in small groups when possible. Consider splitting larger groups into smaller groups.
- Repackage food to minimize waste.
- Use a map and compass to eliminate the use of marking paint, rock cairns or flagging.
Travel and Camp on Durable Surfaces
- Durable surfaces include established trails and campsites, rock, gravel, dry grasses or snow.
- Protect riparian areas by camping at least 200 feet from lakes and streams.
- Good campsites are found, not made. Altering a site is not necessary.
- In popular areas:
- Concentrate use on existing trails and campsites.
- Walk single file in the middle of the trail, even when wet or muddy.
- Keep campsites small. Focus activity in areas where vegetation is absent.
- In pristine areas:
- Disperse use to prevent the creation of campsites and trails.
- Avoid places where impacts are just beginning.
- Pack it in, pack it out. Inspect your campsite and rest areas for trash or spilled foods. Pack out all trash, leftover food and litter.
- Deposit solid human waste in catholes dug 6 to 8 inches deep, at least 200 feet from water, camp and trails. Cover and disguise the cathole when finished.
- Pack out toilet paper and hygiene products.
- To wash yourself or your dishes, carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap. Scatter strained dishwater.
- Preserve the past: examine, but do not touch cultural or historic structures and artifacts.
- Leave rocks, plants and other natural objects as you find them.
- Avoid introducing or transporting non-native species.
- Do not build structures, furniture, or dig trenches.
- Campfires can cause lasting impacts to the backcountry. Use a lightweight stove for cooking and enjoy a candle lantern for light.
- Where fires are permitted, use established fire rings, fire pans, or mound fires.
- Keep fires small. Only use sticks from the ground that can be broken by hand.
- Burn all wood and coals to ash, put out campfires completely, then scatter cool ashes.
- Observe wildlife from a distance. Do not follow or approach them.
- Never feed animals. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
- Protect wildlife and your food by storing rations and trash securely.
- Control pets at all times, or leave them at home.
- Avoid wildlife during sensitive times: mating, nesting, raising young, or winter.
Be Considerate of Other Visitors
- Respect other visitors and protect the quality of their experience.
- Be courteous. Yield to other users on the trail.
- Step to the downhill side of the trail when encountering pack stock.
- Take breaks and camp away from trails and other visitors.
- Let nature's sounds prevail. Avoid loud voices and noises.
