Mountain progression planner
Build a research shortlist from region, month, elevation, activity style and self-reported route experience.
Build a shortlistTools
Mountain planning, comparison and discovery tools
Use practical tools built around transparent assumptions. Calculations run locally where possible and avoid pretending that a simple formula can replace current mountain conditions or professional judgment.
Acclimatization planner
Check sleeping-elevation changes across an itinerary and identify plans that rise aggressively.
Open plannerMountain conditions estimator
Estimate temperature change with elevation and calculate wind chill from a wind speed you provide.
Estimate conditionsAltitude pressure and oxygen explorer
See how standard atmospheric pressure and oxygen partial pressure decrease with elevation.
Explore altitude pressureExpedition cost planner
Build a complete trip budget from current costs for travel, permits, guiding, equipment, accommodation and contingency.
Build a budgetElevation gain calculator
Distinguish summit elevation from net gain and gross ascent across a route sequence.
Calculate ascentMountain height visualizer
Place three mountains on the same sea-level baseline and compare summit elevations proportionally.
Visualize heightPeak comparison visualizer
Compare elevation, prominence, activity, glacier travel, season and permit context side by side.
Compare peaksRoute context explorer
Review route style, glacier context and structured altitude-stage information where verified data is available.
Explore routesSeason explorer
Scan common climbing and trekking months across the mountain dataset.
Explore seasonsPermit and access explorer
Review contextual permit and access notes without reducing complex rules to a yes-or-no field.
