Hiking
The Redfish Lake to Alpine Lake trail plunges you deep into the Sawtooth Wilderness, offering a quintessential Idaho alpine experience. You'll traverse through dense conifer forests, marvel at the immense boulders of the "Garden of the Giants," and climb steadily through switchbacks that reveal increasingly dramatic views of the Sawtooth peaks. The reward is the serene, crystalline waters of Alpine Lake, nestled in a rugged mountain basin, a perfect spot to soak in the high-country atmosphere.
This moderate hike covers 5.5 miles (8.8 km) with a substantial 1812 feet (552 metres) of elevation gain, typically requiring about 3 hours and 12 minutes. Many hikers opt for a boat shuttle across Redfish Lake to shorten the initial approach, allowing more time for the alpine sections. As it's in a wilderness area, remember to pick up a self-administered wilderness permit at the trailhead, and plan your visit for late spring to early fall for the best conditions.
This route is a gateway to the vast Sawtooth Wilderness, known for its pristine nature and geological wonders. Beyond Alpine Lake, the trail connects to other multi-day backpacking options, making it a popular starting point for deeper explorations. The area is also known for vibrant fall colors from huckleberry bushes in September, adding another layer of beauty to the already stunning landscape.

Yes, the route primarily follows the Redfish Creek - Baron Creek Trail for much of its length. It also briefly intersects with the Redfish Inlet Trail near the beginning.
Given the moderate to strenuous difficulty and significant elevation gain, bring plenty of water, snacks, sturdy hiking boots, and layers of clothing. Sun protection, a map, and navigation tools are also highly recommended for a wilderness experience.
The Redfish Lake area, where the boat shuttle departs, offers amenities such as a ferry dock and campground. However, once you take the shuttle and enter the wilderness, there are no facilities, so plan accordingly.
The initial, more gradual section from the boat dock to Flatrock Junction might be suitable for families. However, the sustained and steep climb to Alpine Lake is quite challenging and might be too strenuous for younger children or those not accustomed to significant elevation gain.
