Embark on the Emerald Lake Loop, a demanding jogging route that takes you deep into the rugged Alaskan wilderness of Kachemak Bay State Park. This difficult 17.5-mile (28.2 km) journey features a significant 2329 feet (710 metres) of elevation gain, promising a substantial workout over an estimated 3 hours and 47 minutes. As you push through the varied terrain, you will discover the serene waters of Grewingk Lake before reaching the beautiful Emerald Lake, offering moments of quiet solitude amidst the expansive landscapes.
Planning your visit requires careful consideration, as access to the Saddle Trail Trailhead is exclusively by water.

Always be prepared for the unpredictable Alaskan weather by carrying sufficient supplies and layers for this extensive and remote adventure.
The Emerald Lake Loop stands out as a premier jogging experience within Kachemak Bay State Park, connecting you to two of its most prominent natural features. The trail offers a unique opportunity to immerse yourself in the raw beauty of the region, far from paved roads and urban distractions.
