O’Brien Lake Trail

O’Brien Lake Trail is a hard 10.4-mile (16.7-km) out-and-back from Taylor Creek Day Use Area. Follow the Taylor Lake Trail through forest to the O’Brien junction in the meadow near Taylor Lake, then take the rougher branch to the lake below Mount Bell. The distance is the full return walk; the map traces the physical corridor once. This route goes directly to O’Brien Lake and does not include the optional Taylor Lake spur.

The connected mapped route measures 16.7 km round trip. Some directions list 18.8 km for the direct outing without explaining the extra distance, so check which line you are following. Allow about six to seven hours; the long climb and rough final branch take more time than the mileage alone suggests.

The trail climbs steadily through forest, with switchbacks, creek-side stretches, footbridges and occasional openings near the meadow. The main Taylor Lake Trail is much easier to follow than the O’Brien branch, but it is a long uphill approach before you turn. Taylor Lake itself is a separate short detour; it is a worthwhile add-on if you want both lakes, but it adds distance and time.

At the junction, cross the creek and follow the narrower, less-maintained tread toward the lake. This final section has roots, rocks, wet ground, short ups and downs, and occasional fallen trees; it can be slower and harder to follow. The mapped route ends at the lake shore. Turn back there; continuing beyond the lake is a different outing.
