Goodwin Lake - Granite Creek Thru Hike

The journey begins at the Goodwin Lake trailhead. Goodwin Lake and Jackson Peak are popular day hikes, so expect some trail traffic. The trail gradually ascends, with stretches that feel flat, leading to Goodwin Lake. Consider filtering water here, as the next reliable water source is about three miles away. If the car shuttle setup has delayed your start time, Goodwin Lake is an excellent first night's camp.From the lake, follow the trail around its eastern shore and begin the steep switchbacks up toward Jackson Peak. If you have the time and energy, drop your pack and take the opportunity to summit Jackson Peak for stunning views.Afterward, the trail descends gradually into the Flat Creek valley, staying high along the eastern slopes. Good camping spots can be found in the headwater meadows below Cache Peak, though even better campsites await about two miles farther ahead at Turquoise Lake.From Turquoise Lake, it's all downhill. The trail follows Granite Creek, descending at a gentle grade with some steeper sections as the valley narrows into a canyon. It's about 12 miles from Turquoise Lake to the Granite Creek trailhead. If you plan to camp along this stretch, consider stopping sooner rather than later, as campsites become scarcer as you approach the trailhead.At the end of the trail, you'll find both developed hot springs and free, natural hot springs down the road below Granite Creek Falls. Keep in mind that if you're backpacking this route between April and July, the developed hot springs will likely be your only option due to high runoff from snowmelt.

The developed hot springs have been around since 1933. A pool near the location of the undeveloped hot springs was used for a scene in the "River Runs Through It".
