**Location & Access:** Henrys Lake South Shore offers an undeveloped gravel boat ramp located at 6,470 feet elevation in Island Park, Idaho, approximately 15 miles west of West Yellowstone, Montana and 60 miles northeast of Rexburg. Access via Red Rock Road off Highway 20 (milepost 398), then north for about 5 miles.

**Facilities & Requirements:** This is a primitive access point with a boat ramp and basic camping available at no charge. All paddlers and boaters should note that Idaho's Invasive Species Law requires IISF stickers for any registered boats and non-motorized vessels (kayaks, canoes, rafts) over 10 feet in length. Inflatable vessels under 10 feet are exempt. Contact (208) 525-7121 for sticker information. Camping is limited to 10 days within any 30-day period, and pets must be leashed. The site features a wildlife-viewing platform and is known for excellent trout fishing. Road conditions can become hazardous when wet or snow-covered, so check conditions before visiting, especially in winter months.

Henry's Lake lies high in a mountain bowl (elev. 6,470 feet) 15 miles from the west entrance to Yellowstone National Park. With a backdrop of Sawtell Peak, the shallow lake is known for its trout fishery. The Henry's Fork of the Snake River originates here, just below the Continental Divide between Idaho and Montana. The South Shore Boat Access has an undeveloped boat ramp, primitive camping, fishing, and a wildlife-viewing platform. Additionally, this is stop along the Idaho Birding Trail, and a state-designated Important Bird Area. Wildlife abounds in the Henrys Lake area, including several rare species such as the white spruce, found nowhere else in Idaho. The Henrys Lake area is an important migration corridor, so if you come at the right time, you might see moose, elk, or pronghorn migrating back and forth from summer range in the highlands to winter range in the desert north of St. Anthony. We hope you enjoy your experience at Henrys Lake and take home some memories with you. If you follow “pack it in, pack it out” principles, you will help make your next visit, as well as that of others, just as special.
