Yes, big trailers can get in there. Ours is only a 2H GN, but the other 4 rigs were all 3 & 4H GN's. About the road to Sheridan~I wouldn't consider it too bad of a climb. We only drove down both years, as we had camped down at Ten Sleep, WY each trip before heading up to B.J. If you have the time, it's a great place to camp 2 or 3 days prior. We camped at Ten Broek Campground where the owners (Daryl & Bonnie) loaded us all up in their large stock trailer and drove us up into the Big Horns. We chipped in for gas, but Daryl just parked up in the mts, and then lead us out. It was an easy walk into the cute little town of Ten Sleep where we visited the saloon, ice cream parlor, eateries and shops. Take a ride up above the town, and it's like riding on the moon~high, dry but a beautiful vista of the city which sits upon an artesian well.

We then drove up rte. 14 from Greybull up to B.J. A stop at Shell Falls is a must. The drive itself is gorgeous and an easy drive.

I think a lot of Bear Lodge's busy season is winter sports, but there were plenty of others camping during late July/Aug when we were there. Bear Lodge is located at the junction of 14A & 14. You DON'T want to pull your rig on 14A, as it's a very steep grade. Our fees were $12.50/night for W/E. Those who needed full hook-ups paid $18.50. No extra for horses. One couple brought their own panels to make a pen whereas we other 5 rigs used picket lines. You need certified weed-free hay which we ordered ahead of time and had delivered right to our sites. Bring your own groceries as the prices at the lodge's little convenience store were outrageous, but maybe that's better now. I snapped a pic of pkg of a 1 lb. package of bologna with an expiration date marked 7/18/05. I took the pic on Aug. 4 with a hefty price tag $8.39!!! W/o picture proof, who'd believe it?

You ride right out of camp into the forest. The riding is endless. You can ride the wide open spaces hardly ever crossing fences. You can ride the Tongue River. Twin Buttes is a pretty ride. You ride upon moose often and coming upon a lone shepherd carrying a lost sheep on his horse was like a scene out of "Brokeback Mountain". That encounter actually got most of our horses a bit nervous~whether it was the site or the smell. But the lone little camper parked amidst the huge herd of sheep down in the valley was breathtaking, too.

A hike down Porcupine Falls is a MUST. We drove there; no horses allowed down that trail~strictly hiking. I can list lots more, but don't want to bombard this forum. Let me know if you want more info!

Where did you find the certified hay?

I used online resources. Also, you can call the forest ranger in that area for help. He/she could probably give you a private grower like we used. Here are some sites I checked with our first trip till my friend found a private grower who hauled the hay right to our camping spots.

Ten Sleep was a great way to start off our WY riding. The campground owners trailered us up into the Big Horns, usually a little over an hours drive. Daryl just drove up and parked~no trailhead to bother with. So exciting.

*interesting watering hole on the way to Garden of the Gods from Bear Lodge camp~just a pipe sticking

up from the ground with running water. The horses loved it, and each one drank w/o hesitation.

I have tons more, but don't want to hog up too much space. Believe me, it is truly God's Paradise and

with tons of riding.
