Park Comparison
Great Smoky Mountains vs Olympic
Two iconic parks, different strengths. Here's how they stack up.

The Quick Take
Great Smoky Mountains
Great Smoky Mountains is the most-visited national park in America: 12 million visitors a year, no entrance fee, and 850 miles of trail spread across 816 square miles of Southern Appalachian forest. Cades Cove's 11-mile loop preserves 19th-century homesteads and reliably puts black bears, elk, and deer in view. Clingmans Dome at 6,643 feet hands you the highest point in Tennessee. The trade-off is the obvious one: this park is busy nearly all the time, October weekends approach gridlock, and Cades Cove traffic can take three hours to circle.
Olympic
Olympic packs three completely different ecosystems into 1,442 square miles: temperate rainforest dripping with moss in the Hoh Valley, glacier-capped peaks topping out at 7,980-foot Mount Olympus, and 73 miles of wild Pacific coastline studded with sea stacks. Few parks combine that much variety. With 3.7 million annual visitors and a peninsula geography, the trade-off is logistics: driving between the rainforest, the alpine, and the coast eats hours, and the rain (200 inches a year in the Hoh) defines half the calendar.
At a Glance
The Crowd Picture
Both parks draw millions, but the crowd experience is different.
Great Smoky Mountains
Great Smoky's 12 million visitors are roughly three times Olympic's, packed into a smaller footprint with no entrance fee to slow anyone down. October's 1.5 million visitors create traffic jams the length of the Newfound Gap Road, and Cades Cove can take hours to circle on a peak weekend. Laurel Falls Trail, Clingmans Dome parking, and the Roaring Fork Motor Nature Trail are the predictable bottlenecks. Backcountry trails past the first three miles thin out fast; the 850-mile trail network absorbs determined hikers gracefully.
Olympic
Olympic draws 3.7 million annual visitors but spreads them across three regions that rarely overlap: most rainforest visitors never see the coast, most alpine visitors skip the Hoh. July and August funnel crowds to Hurricane Ridge and the Hoh Visitor Center, where parking fills by 10 a.m. The coast stays quieter except at Ruby Beach. Off-peak, the park feels remarkably empty given its size; even Lake Crescent and Sol Duc see manageable traffic from October through May.

Trails & Activities
Both parks are trail-rich, but they cater to different trip styles.
Great Smoky Mountains
Great Smoky's 850 miles of trail include one of the East's most demanding day hikes: the 11-mile Alum Cave Trail to Mount LeConte's summit, climbing 2,763 feet through old-growth forest to a backcountry lodge. Laurel Falls offers an easy paved 2.6-mile family option to an 80-foot waterfall. The 5.4-mile Rainbow Falls and 3.6-mile Chimney Tops give moderate-to-strenuous variety. The 70-mile Appalachian Trail crests the park's central ridge. The character is dense, humid, hardwood; fall color in mid-October is spectacular.
Olympic
Olympic's 570 miles of trail let you hike a temperate rainforest, an alpine ridge, and a Pacific beach in three different days. The 17.5-mile Mount Olympus Trail through the Hoh is the park's signature backpack, climbing nearly 3,600 feet from rainforest to glacier. The 17-mile High Divide Loop traces alpine ridges with panoramic views to the coast. Easier options like the 1.9-mile Marymere Falls and the 3-mile Rialto Beach walk give the same ecosystem variety in shorter form.
Camping
Great Smoky Mountains National Park offers significantly more camping options.
