Perched on the rugged face of McQuirks Mountain within the Green Zone, 5.7 In Slippers offers a brief but engaging trad climb that tests your steadiness and gear skills alike. At just over 100 feet, this single-pitch route carves a line through steely cracks and jagged holds, demanding more than just brawn—it requires sharp attention to protection and movement in equal measure.

The climb begins with an inviting approach: moderate crack systems offer familiar hand jams that ease you upward, warming your body and your confidence. But don't let the easy start fool you. Midway through, a subtle crux presents itself in a compact section where holds tighten and gear placements become less forgiving. This section nudges you to focus intently—choose each move deliberately, and carefully assess your protection before committing. The risk lies not in immense technical difficulty but in the precision and patience the route demands.

Protection is straightforward but needs care. Racking a single set of cams to 3 inches prepares you well for the placements here, though be ready to navigate small seams and thin edges that push you to feel the rock's textures and fit your gear just right. The anchors are simple—a solid tree at the top provides a natural belay spot, emphasizing the climb’s backyard appeal and straightforward descent.

Surrounding the route, the Green Zone offers a quiet wilderness atmosphere with trails leading through dense forest patches and open ridges. The ascent to McQuirks Mountain is accessible but unassuming, making this climb an ideal choice for a half-day adventure where you can enjoy a mix of physical challenge and natural quietude.

Timing your climb early in the day can be advantageous: the west-facing wall catches the morning sun, warming up cool rock but retreating into shade by mid-afternoon. The best seasons tend to be late spring through early fall when the weather is stable, and the woodlands around the base buzz softly with insects and bird calls.

While the route’s grade is friendly at 5.6 PG13, careful preparation is key. Protecting the crux moves calls for precise placements, and the tricky section is unforgiving to rushed attempts. Pack enough water, wear shoes with strong edging capability, and double-check your anchor setup for a smooth, satisfying experience.

Whether you’re brushing up on crack techniques or seeking a straightforward climb with a subtle challenge, 5.7 In Slippers wraps practicality and adventure into a compact, memorable package. It’s a spot to refine your trad skills without the fuss of long approaches or complex logistics, all set in the quiet majesty of New Brunswick’s wild lands.
