Ryder Lake is accessed via the Stillwater Trail, beginning at the Christmas Meadows Trailhead off of Mirror Lake Highway. The trail heads due south from Christmas Meadows along the Stillwater River. It winds through lodgepole pine forests and skirts alpine meadows, gradually gaining elevation.

After 3 miles, the trail forks. Take the right fork, as the left leads to Amethyst Lake (another popular hiking and backpacking destination). Another 1.5 miles later, the trail forks again. This time, take the left fork (the right fork leads to Kermsuh lake). Both junctions are well-marked with posted wooden signs. The trail continues south for another 1.5 miles before slowly turning southwest. The trail ascends a steep gulch for 0.5 miles, before plateauing for the remaining 1.5 miles.

Many small lakes dot the landscape before reaching Ryder Lake. Hikers will know when they reach Ryder Lake, however, as it is far larger and more prominent than those already passed. It features many campsites around its shore.

Those interested in fishing (with a fishing permit, of course) will find many opportunities to fish at the lake, as well as along the Stillwater river on the hike up. The High Uintas are notorious for their fickle weather, so be sure to bring warm clothes and rain gear. A camera is also a must for capturing the amazing alpine landscapes, as well as wildflowers and wildlife that are present during summer months. The trail features several stream and marsh crossings, so be prepared to get your feet wet. Amethyst Lake attracts the majority of visitors from Christmas Meadows, so expect plenty of solitude around Ryder Lake.
