Plan your mountain day with confidence
SummitAgent checks weather, avalanche conditions, road access, gear needs, and trail reports — then gives you a clear go/caution/avoid recommendation for your chosen route and date.
How it works
- Pick a mountain or trail and your planned date.
- Read the verdict card first — GO, CAUTION, or AVOID with the top reasons why.
- Check the weather forecast for trailhead and summit conditions.
- Review avalanche hazard if your route crosses avalanche terrain.
- Look at recent trip reports for on-the-ground conditions.
- Use the 3D map to preview your route and terrain.
- Export your plan, share it, or create a Meetup event.
What's in a planning brief
When you pick a mountain and date, SummitAgent builds a brief with these cards. Each card cites its sources so you can verify anything.
Verdict
