Fourth Avenue Trail is a short mountain biking route in Oregon, about 0.9 miles from Carson Heights. The trail is an out-and-back that runs about 0.26 miles, with a front-loaded climb that reaches a high point of 189 feet. The total elevation gain is 45 feet, and the route is nearly flat after the initial rise, which peaks at about 2% grade roughly 0.06 miles from the start. Summer is the most comfortable time to ride. Typical averages from a nearby weather station show July and August highs around 80°F, with only three or four wet days a month, while winter brings highs in the mid-40s and rain on most days. Several other trails sit close by, including the North Horse Loop and Boones Ferry Horse Trail, each about 0.2 miles away, and the West Horse Loop at 0.4 miles. Paddlers can head to Fanno Creek, about 3.9 miles off.
