Yellowstone Thorofare Expedition

Yellowstone Thorofare Expedition

A true bucket list expedition into the heart of the most remote wilderness area in the lower 48.

The Greater Yellowstone Ecosystem is one of North America's largest and most important intact ecosystems. The heart of that ecosystem is the Thorofare region. Straddling the southern boundary of Yellowstone National Park and the Teton Wilderness, the Thorofare is further protected by Grand Teton National Park to the west and the Washakie Wilderness to the east. To put it simply, the Thorofare is the furthest point from a road in the lower 48 states. It is also the backdrop for one of our lifetime's greatest conservation success stories. The endemic Yellowstone Cutthroat trout population in Yellowstone Lake return to this area annually to spawn. Bears, eagles, otters, ... the entire ecosystem counted upon the spawn. Those same Yellowstone Cutthroat trout populations were decimated by the introduction of Lake Trout in Yellowstone Lake, then hit even harder by the 1988 Yellowstone fires, and the entire system felt the hit. Through aggressive conservation efforts, Yellowstone Cutthroat continue to make a comeback, and with them come a handful of only the most adventurous anglers. Two days of hiking will bring us to our base camp at the headwaters of the Yellowstone River. For 5 days, we will explore the Yellowstone, Thorofare, and other small tributaries. Walking into a wilderness this vast is like stepping back in time. Historic ranger cabins are the only sign of human development, and wildlife encounters are more common than human. Chances are you will never be in a place this wild again. * Offered in partnership with Martin Outfitters Special-Use Permit # BUF485802 an equal opportunity service provider.

On departure day, your trip leaders will help you check in and wait with the group until the last participant's flight leaves the ground.

Do I need to have fly fishing experience? 

Our Adventures are made up of students ranging in experience from total beginner to expert. Regardless of your skill level, your guides, along with a variety of water fished, will make you a more confident and independent angler. 

Do I need my own fishing equipment?

Students are responsible for their own fly rod, reel, line, and a few other personal fishing items. Please get in touch with us for a complete packing list. Don't have your own gear? Not a problem. We have top-quality Orvis rods and reels available to rent.

What other equipment will I need?

We will send you a complete packing list if you are interested in signing up for one of our Adventure Academies. Group gear, such as tents, stoves, etc., is all provided by LFFE. Personal equipment such as sleeping bags and backpacks are all available to rent.

Lillard's programs give your child the chance to focus on fly fishing while exploring the best nature has to offer. Our son has done two of these camps in the last two years and each time has said "it is the best two weeks of the year!" Will Lillard and his whole team create an awesome adventure around fly fishing, but also promotes independence of the child (packing their own pack!) and friendship between the anglers as well! We highly recommend this experience!

Lillard Fly Fishing Expeditions was started in 2010 as a graduate thesis for my Master's Degree in Environmental Conservation Education at NYU. The operating premise was simple - by coupling amazing wilderness fly fishing camps for teens with environmental education and service learning we can help inspire future generations of fly fishing conservationists. We have been growing our unique list of trips and experiences ever since.

When it comes to choosing a summer program for your teen the options are endless. For the teen who loves to fish, be outside, and has a strong sense of adventure we have made the choice easy. We are the leader in teen fly fishing adventures and are dedicated to providing the best backcountry fly fishing experience with opportunities for teens to engage in leadership training, community service, and backcountry camping.
