How we built this page.
An independent guide using official data. Not affiliated with or endorsed by the National Park Service.
- Crowds
- 2021–2025 monthly averages. NPS recreation visits, compared with the park’s own busiest month. Visits are not unique visitors or a count of people on a trail.
- Weather
- 1991-2020 climate normals. NOAA’s Moran 5WNW HCN station. These describe typical weather at the station, not every part of the park or a forecast.
- Roads & lodging
- Normal seasonal schedules. NPS guidance and official operator information. Confirm access, hours and availability before you travel.
Historical records and data-quality checks
- Visit history: 1979–2025 NPS monthly recreation visits.
- Weather history: 1911–2025 daily observations, separate from climate normals. We average daily highs and lows and total the rain for each month.
- Complete months only: every day must pass our quality checks for that metric. Missing or incomplete records stay blank; we never interpolate.
- Excluded measurements: flagged, presumed-zero and lagged values. Trace rain counts as zero measurable rainfall.
