Groove Tube offers a captivating line along the left wall of The Alcove in the Pool Wall sector near Ouray, Colorado. This single-pitch, 90-foot route stands out with its extended, water-formed groove that challenges climbers to rely on solid stemming and body positioning throughout the ascent. The groove’s texture invites you to press firmly against the rock as you navigate its length, feeling the subtle echoes of water’s persistent force shaping this passage over time.

Unlike shorter climbs nearby, Groove Tube demands sustained effort from start to finish, testing endurance and technique more than quick bursts. The route’s sport bolt protection, approximately a dozen strong and spaced with regularity, allows confident clipping though carrying a few extra quickdraws is wise given some uncertainty about the exact count. The grit of the stone combined with the groove’s natural contours yields secure foot placements and hand jams, making this an enjoyable challenge for climbers comfortable at the 5.9 grade.

Starting from the base, the approach leads you to the alcove’s cool, shaded environment, buffered by weathered walls that cradle the climb and shelter you from harsher elements. The surrounding rock hums with quiet energy, as small breezes trace through the pool wall’s cracks and ledges. On a sunny day, the angle keeps you cool without losing warmth, making it an ideal climb during spring and fall when temperatures balance between crisp and comfortable.

For those planning the ascent, solid climbing shoes with reliable edging and smearing capabilities will serve best on the varied rock textures. Hydration is critical here, especially in early summer, when the sun can intensify quickly. Bringing a helmet is strongly recommended—the route sees moderate foot traffic and loose rock occasionally dislodges within the alcove’s confines.

Groove Tube's accessibility from Ouray, a town known for its historic charm and outdoor offerings, means you can combine your climbing day with excellent dining and recovery spots nearby. The Pool Wall sector itself offers a selection of other sport climbs, giving visiting climbers a full afternoon or morning of varied routes within easy reach.

Whether you’re refining your stemming technique or seeking a solid 5.9 with thoughtful protection, Groove Tube delivers a straightforward yet engaging experience. It’s a chance to feel the rhythm of the rock, pushing steadily upward through a groove that guides and challenges in equal measure.
