"The 700L/Plumb Line Area offers a varied collection of south-facing crags and boulder fields along a scenic creekside setting in Wyoming’s Laramie Area. With classic lines ranging from technical cracks to powerful boulder problems, this spot combines accessible hiking with dynamic climbing for a wide spectrum of skill levels."
Located at nearly 8,000 feet elevation in Wyoming’s Laramie Area, the 700L/Plumb Line Area is a dynamic climbing destination that blends a range of south-facing crags with popular bouldering spots. The setting along a riparian creek corridor offers not only a pleasant approach but also a chance to pause and observe local wildlife, setting a calm yet adventurous tone to the day. The area serves as a collective for several named crags including The Acres, The Labyrinth, Hasselhoff, Worm Drive, The Citadel, and the Short Wall — each bringing its own character and climbing style.
Approaches vary depending on your chosen crag. The 700L road, though sometimes gated to protect erosion-prone areas, offers the best access to cooler, tree-lined sections like The Acres and Worm Drive. Alternate access onto 700C is slightly shorter for areas like Plumb Line and Citadel Crag but demands more cautious driving across rough patches and a bit of route-finding on foot. The trail from the parking area is short and enjoyable, following the creek south with stable footing.
The climbing here ranges from boulder problems that build finger strength and technical prowess to moderate trad routes that challenge movement on clean lines. Notable classic climbs like Organic Slab (V1) welcome those easing into the area, while more demanding problems like Eight Ounces To Freedom (V9) reward seasoned boulderers with powerful moves. Trad climbs like Plumb Line (5.9) and Euroboy (5.10) deliver well-regarded challenges with solid protection options, making the area friendly for a mix of skill levels and styles.
Many of the crags strike southward, meaning sun exposure is a central consideration — especially on warm summer days. Enthusiasts should plan their sessions for mornings or late afternoons to avoid the peak sun beating down on more exposed boulders and walls. Spring and fall emerge as ideal climbing seasons here, offering balanced weather and lush views along the creek.
Protection quality is generally very good across the trad climbs, with fixed bolts present but traditional gear often preferred in crack systems. For bouldering, multiple pads and spotters are recommended since many problems are on sun-baked rock with limited natural shade.
The descent from many climbs is a straightforward walk-off or short hike back to approach trails, easing the transition from the action to rest. The forested paths provide quiet spots for regrouping and appreciating the isolation of this Wyoming spot — far from crowded crag scenes.
With a route spectrum concentrated around 5.8 to 5.11 and boulder grades spanning from beginner to advanced, the 700L/Plumb Line Area is a compelling playground for climbers who value variety within a scenic outdoor setting. Combining technical trad lines with accessible bouldering and a pleasant creek-side hike, it rewards both early explorations and dedicated return trips for those getting familiar with the Laramie climbing scene.
Sun exposure on many boulders can intensify heat especially mid-summer, so hydration and timing are key. Some approach roads involve locked gates or rough conditions—check status before arrival. Rock quality is generally solid but always inspect holds carefully before committing, as the area includes both sport and trad routes with varying protection.
Plan climbing sessions early or late in the day to avoid strong sun on exposed south-facing rock.
Use 700L for access to The Acres, Worm Drive, and Hasselhoff; 700C offers quicker, but rougher, access to Plumb Line and Citadel Crag.
Carry more crash pads and spotters for bouldering problems due to limited protection and uneven landings.
Check gate status on 700L road ahead of your trip as it may be closed for erosion control.
Approach varies by crag with access roads 700L and 700C; parking off 700C is the easiest for Plumb Line and Citadel areas. Protection comprises traditional gear plus some bolts on sport lines. For bouldering, bring multiple pads due to sun exposure and limited shade.
