Smoky Mountains in Spring

Spring ushers in cool mornings and pleasant temperatures during the day.

There are over 1,500 kinds of flowering plants that grow in the Great Smoky Mountains, more than in any other American national park.  The park is famous for its displays of mountain laurel, rhododendron, and flame azaleas. Spring wildflowers often are in full bloom by mid-to-late May. The best trails in the park to witness these wildflower fields include the Rich Mountain Loop, the Porter Creek Trail, and the Deep Creek Loop.

Great Smoky Mountains National Park

The Smokies get a lot of two things in the summer: rain and visitors. While the crazy high visitation numbers are undoubtedly due to motorists simply driving through the park’s main roads, the park does see an extremely high number of vacationers in the summer.

When we visited the Smokies in July, almost every morning and evening had rain. It would usually come down in buckets, then the sun would come out and dry it all up. The lesson here is that while you need to be prepared for sudden torrential rain, you shouldn’t let it impact your plans for the day.

Temperatures in the summer here average in the mid 70s for highs, and around 60 °F for lows.

However, it should be noted that all primary roads remain open throughout the winter.
