July 2006 - I just booked passage through the Wind River Reservation to the Ink Wells trailhead. The same price was quoted for either 2 or 3 people. The current cost is $600 round trip for the transportation (total), plus $45 round trip per person for tribal permit fees. That comes out to $245 pp r/t for 3 people, or $345 pp r/t for 2 people.
Ramona still handles transportation through the reservation. Her number is 307-486-2318. She lives next door to the Crowheart store.
Pick-up is normally from the Crowheart store at 8am. Return pick-up from the Ink Wells trailhead is 11am-12pm. You can leave your car at Ramona's house.
A tribal permit is required to cross the reservation. Permits are available from the Crowheart store. The store opens at 7:30am on Saturdays.
