Mount Rainier in April: what the park service says

April brings Mount Rainier's spring, when the park says ephemeral waterfalls run and a quieter, more leisurely trip is possible, though weather may decide which facilities are open. Expect Paradise to top out in the mid-40s°F, and Ohanapecosh, low in the southeast corner, nearer 58°F. Rain is very likely in spring, so check the status of roads, campgrounds and trails before you plan the day.
