June is the useful early-summer comparison: 48% of peak at Olympic and 53% at Rainier. Both are near half their own peak in June. That does not promise snow-free mountain walks at Rainier. Check its seasonal planning guide before choosing dates.
September averages 420,210 visits at Olympic and 234,962 at Rainier. By October, their relative shares fall to 42% and 32%. Compare these months with your intended trip, rather than choosing the lowest bar alone.
Relative visitation, month by month.
These picks compare distance below each park's own peak. A gap below ten percentage points is too small for a preference here. Access and the trip you want still decide.

|---|---|---|
| January | Either | January: Olympic 13% of peak; Rainier 6%. Similar seasonal position; choose by your planned stops. |
| February | Mount Rainier | February: Olympic 15% of peak; Rainier 4%. Rainier has the lower relative share. Verify the route for your dates. |

Different trips, not a ranking.
A rainforest walk and a mountain meadow walk answer different wishes. Olympic also has mountains; Rainier also has forests. The choice above highlights what to build a short visit around, rather than claiming either park has only one kind of scenery.
For weather and seasonal access, use the Olympic and Mount Rainier timing guides. Before driving, check Olympic conditions and Rainier conditions. These historical charts cannot tell you what is accessible today.
Common questions.
Should I choose Olympic or Mount Rainier for one day?
Choose Olympic if the rainforest or beach is your priority, or Rainier if you want a mountain-focused day. Keep the plan to one area and check travel time from your lodging. This page does not assume that every trip starts in Seattle.
How close is Olympic National Park to Mount Rainier?
There is no single useful park-to-park distance: your Olympic stop and Rainier entrance determine the drive. Map those exact endpoints. Start with Olympic's directions guide and Rainier's official area pages above. Plan separate park days rather than assuming they fit into one outing.
Which park has fewer summer visitors?
Rainier records fewer total recreation visits. Its busiest month is July, while Olympic peaks in August. In July, Olympic is at 80% of its peak and Rainier at 100%. Those park-wide counts cannot tell you which trail or parking lot will be quieter.
How we compare these two
Monthly figures are average recreation visits for 2021–2025. OLYM and MORA are separate park reporting units. Each curve divides that park's monthly mean by its own highest monthly mean. The ten-point comparison rule is an editorial cutoff, not a statistical significance test. Recreation visits count visits rather than distinct people and do not measure parking demand. All figures here come from the NPS Visitor Use Statistics Data Package, 2025.
