Highlights
The Natural Bridge Loop is a scenic trail with a hiking option located just northeast of Buena Vista. The trail snakes back and forth over small ridges and through steep gullies before reaching the Natural Bridge rock formation. While an impressive photo opportunity from the road, the optional .75 mile hike to the bridge allows for an up close look and an amazing view of the Arkansas River Valley below. The return trip is equally as impressive with panoramic views of the 14,000' Collegiate Peaks as the backdrop. Bring your hiking gear and some water if you plan to hike to the bridge as it's a steep non-maintained trail up the mountainside.

Description
This trail is part of the Fourmile Travel Management Area northeast of Buena Vista. The Natural Bridge route follows FS 373 and part of FS 311 making a large loop. The road surface is mostly sand and/or smooth dirt as the trail climbs up and out of the valley. There are some steep gullies to navigate before the trail drops in elevation near the Natural Bridge hiking trail. The route then circles back toward Buena Vista giving a panoramic view of the Collegiate Peaks for the return trip.
