Square Lake is an alpine tarn located at about 7,021 feet (2,140 m) elevation. It is accessed via a short spur trail off the main Ides Cove Loop Trail. While the spur trail itself is short, the overall journey to reach the lake is considered to have a moderate hiking difficulty due to the alpine environment and elevation gain involved in accessing the Ides Cove Loop Trail.
The time it takes to hike to Square Lake depends on your starting point and the specific route you choose along the Ides Cove Loop Trail. The lake itself is just a few hundred feet down a spur trail from the main loop. Hikers should plan for a full day to comfortably complete a significant portion of the Ides Cove Loop Trail and visit the lake, accounting for elevation and terrain.
While the overall area is alpine and involves moderate hiking, families with older children or beginner hikers might consider shorter segments of the Ides Cove Loop Trail. The spur trail to Square Lake itself is short once you reach the main loop. However, the journey to the trailhead and the initial sections of the Ides Cove Loop Trail should be evaluated for suitability based on the family's experience and fitness levels.
Generally, trails in the California Coast Ranges, especially in national forests or wilderness areas, often permit dogs on leash. However, specific regulations can vary. It's always best to check with the local land management agency (e.g., Shasta-Trinity National Forest) for the most current rules regarding dogs on the Ides Cove Loop Trail and around Square Lake before planning your visit.
Square Lake is an alpine tarn at over 7,000 feet, so winter conditions can be severe. The area will likely be covered in snow from late autumn through late spring, making access challenging. Winter hiking would require specialized gear such as snowshoes or skis, and experience with avalanche safety and navigation in snowy terrain. The best time to visit for typical hiking is from late spring through early autumn when trails are clear.
Given the alpine environment, hikers should always be prepared for changing mountain weather. Essential gear includes sturdy hiking footwear, layers of clothing (including waterproof outer layers), plenty of water, snacks, sun protection (hat, sunglasses, sunscreen), and a map and compass or GPS device. Depending on the season, trekking poles can also be beneficial.
