The Loch Swimming Safety Guide safety guide

About This Route

The Loch (short for The Loch Vale) lies at the end of a 5.8-mile round-trip trail from Glacier Gorge Trailhead in Rocky Mountain National Park, at 10,500 feet amid Icy Peak and Stonewall Peak. This permitted swimming spot (unlike nearby restricted lakes) features a large, wind-sheltered tarn ideal for careful strokes, though glacial origins ensure bone-chilling temps. NPS permits confirm access; the forested approach via Alberta Falls offers shaded relief. Ideal for experienced hikers seeking solitude over Jewel Lake crowds.

Safety Considerations

Wind shear on open water causes capsizing risk; enter perpendicular to swells. Hypothermia amplified by elevation; monitor core temp. Boggy shores suck boots; use boards for stability. Bear activity peaks dawn/dusk; secure food. Lightning exposure high; NPS data shows 20+ strikes yearly nearby. Acclimatize 24 hours prior. Group minimum two; rotate spotter duties every 5 minutes.

Essential Gear

Drysuit for variable winds (Kokatat Gore-Tex). Neoprene hood and pogies. USCG PFD. Waterproof headlamp for evening returns. Water filter (Sawyer Squeeze) despite no drinking advisories for swimming. Insect repellent for mosquito-heavy Loch Vale.
