Hi Gregory, and welcome to planDisney!
First, I am a fan of the beautiful surroundings found at
The Campsites at Disney's Fort Wilderness Resort! I must admit that the
Horseback Trail Riding at Fort Wilderness Resort has been on our bucket list for a while, so I can understand wanting to experience it for yourself.
I did some research, and it looks like the calendar provides dates out to around 90 days from the date you search. I took the liberty of doing a sample search for dates, and it looks like your date of July 13 is available and has the following times: 8:00 AM, 9:30 AM, 11:00 AM, 12:30, and 2:00 PM.
You can book the Trail Rides by calling 407-WDW-PLAY or walk in at the front barn at the
Tri-Circle-D Ranch, located at the entrance of Disney's Fort Wilderness Resort & Campground. The 45-minute horseback trail ride does incur a per person fee, but it is worth it to have a different experience while you are at
Walt Disney World Resort!
We would love to help you in any way we can during your planning phase; let us know how we can help.
Have a magical experience!
