The GDTA’s largest fundraiser of the year.
Did you know that the Trail Supporter Campaign has been the GDTA’s largest source of non-grant funding? This funding is critical to enable all the work that happens behind the scenes in order to build, maintain, and promote the GDT. Your continued support contributes to the GDT’s legacy, improving and protecting the trail for future hikers who will walk 1095 km from Waterton to Kakwa.
