Thomas Falls Challenge Course is conveniently located  between Dallas and Shreveport in Diana, Texas - nestled in the Piney Woods of Northeast Texas. between Longview & Ore City, at one of the highest points in East Texas. 

We take pride in training individuals and groups in the sport of climbing and zip-lining. Our well trained staff comes from backgrounds such as rope rescue technicians, active fireman, and peace officers.

From newlyweds to retired couples, individuals, groups, organizations, birthday, anniversary or special occasion parties, we welcome them all.  Our zip-line guides can escort you on a private or family zip-line experience, or assist you in team building exercises for school, church, organizations, scout troops or company groups.

How zip-lining at Thomas Falls helps the community:

For each Canopy Tour we book, $1 goes toward Gold Star Family Day, a local one day event providing free zip-lining, lunch and water obstacles at Thomas Falls. Gold Star Families are those that have lost love ones in the War on Terror or other military exercises. Thomas Falls is proud to support our troops and their families.

  • I love adventure and Zip lining is right up my alley. I invited one of my best friends and her family to join me and my special needs son to celebrate my birthday at Thomas Falls. I was nervous that my son would not understand how and when to break and that he might not be able to complete the course. The guides and staff were amazingly patient and incredibly awesome to my son, Logan. They took the time to show my little ADHD, Autistic, Down syndrome having son how to safely operate the pull break and made sure that he was safe. Some might be thinking "of course they did, they didn't want to be liable". If that were true they could have just asked us to leave when Logan didn't get it right after the 3rd try. Instead we brain stormed on wording and came up with commands that he would understand and it WORKED! He was able to complete the course. The grounds were very well kept and the picnic area is beautiful. The perfect location for a wedding or other gathering. Something else that I loved was the wagon ride from zip to zip. I have been before where I had to hike from zip to zip and that just zaps so much of the energy and fun. I would HIGHLY RECOMMEND this location.

  • It was a neat place. All the staff were very professional. They knew their jobs and carried them off successfully. That's good since the job was to keep their clients (us) safe.

  • I did the zipline at one of your competitors yesterday and wanted to let you know how you measured up. It took us about an hour and a half and we walked up a TON of stairs. It was fun zipping over ......, etc., but I really preferred the scenery and platforms at Thomas Falls. Their guides didn't interact with us very much. Maybe they were tired but your guides were WAY better.

    What makes your zipline experience stand out is the scenery, the challenge log - no one else has anything like that - your suspension bridge, your guides, the tractor ride to the long platform, and the tractor ride back. You have great facilities in the heart of the Pineywoods and we're planning another trip your way in the fall.

  • I even got the T-Shirt!
