Climbing Navigation & Tactical Crag Maps — Precision Approach Pathfinding

Navigate remote crags with tactical confidence. Sendr provides high-fidelity approach pathfinding, offline vector topography, base-of-wall coordinates, descent routes, and smartwatch wrist navigation.

GPS Approach Routing from Trailhead to Wall

Step-by-step approach pathfinding maps every turn from the parking lot directly to the base of your chosen sector or boulder problem. Eliminate bushwhacking and wasted daylight.

Offline Vector Topography & 3D Terrain

Download rich topographic maps before heading out. High-resolution contour lines, cliff bands, boulders, water sources, and descent gullies remain fully visible without cellular coverage.

Suunto & Smartwatch Wrist Navigation

Send approach routes and waypoint coordinates directly to your Suunto or compatible smartwatch. Keep both hands free for trekking poles or scrambling across talus fields.

Interactive Path Studio for Custom Trail Mapping

Create and publish custom approach paths, scramble variations, and descent abseil lines. Snap to established mountain trails or draw freehand lines across rock slabs.
