Calcite Mine and Palm Wash Loop

The main access point for this loop is off Highway S22 within Anza-Borrego Desert State Park. While the initial access is suitable for all vehicles, reaching closer trailhead parking might require a high-clearance 4x4 vehicle due to rugged road conditions. If you don't have a 4x4, you may need to park further away, potentially adding an extra 2 miles each way to your hike.

The terrain is quite varied, featuring packed dirt, loose rocks, and sandy sections within narrow washes. You'll also traverse parts of old jeep roads, which can be steep and rutted. A significant part of the experience involves exploring twisting slot canyons with smooth, water-sculpted sandstone passages, some of which may have boulder-choked sections. Be aware that some portions are shelf roads with blind curves.

This trail offers expansive desert vistas, including panoramic views of Palm Wash, surrounding mountains, and the dramatic Borrego Badlands. The highlight for many are the spectacular slot canyons with their unique geological formations. You can also visit the historic Calcite Mine site, where you might find small, glistening calcite crystals. Another natural landmark is Locomotive Rock, an imposing sandstone formation with intricate cavities.

While generally rated as easy to moderate, the full loop is considered 'difficult' by komoot, covering over 11 km with significant elevation changes. The varied terrain, including sandy washes and potentially rugged jeep roads, along with challenging navigation in some areas, means it's best suited for hikers with some experience. Beginners should be prepared for a longer, more strenuous outing and ensure they have reliable navigation.
