    Route Description for Mason Lake via Ira Spring Trail

    Mason Lake via Ira Spring Trail is a wonderful hike, offering pretty much everything you would want in an outing: gorgeous mountains, carpets of wildflowers, sunny ridgelines, and crystalline alpine lakes. This trail can be used as a daytrip hike or a short backpacking adventure if you arrange to stay at Mason Lake Backcountry Camp, which is a fantastic spot. This trail does get quite busy, but it’s well worth the effort to enjoy the picturesque setting. The trail honors late conservationist and nature photographer Ira Spring.

    The hike begins from the parking lot, passing through thick forest along some leisurely switchbacks. You’ll cross Mason Creek at about 1.3 km. A new bridge has been constructed here to safely ferry hikers across in all seasons, as this was previously a difficult crossing when the water hit its springtime highs.

    After crossing the bridge, continue through the forest to a junction at 2.6 km. Go left here. You’ll begin to gain elevation more aggressively, switchbacking above the treeline into a fantastic alpine meadow. The views here reward your efforts, which continue to hte junction with the Bandera Mountain Trail. Stay left again.

    After the junction, climb north to the summit crest, which provides excellent views over the surrounding mountains and to Mount Rainier on clear days. This is the best spot on the hike to stop for photos!

    Descend over the north end of the ridge, dropping about 91 m in elevation to Mason Lake. The trail wraps around the lake to the camping areas. This is the end of the trail, but there are a couple of extensions possible to lengthen your trip.

    Option 1: You can make a side trip to Bandera Mountain by taking the Bandera Mountain Trail at the junction. This is less than a mile in distance but quite steep, gaining 213 m in about 0.8 km.

    Option 2: Take the main trail around the north bank of Mason Lake to the junction with Mount Defiance Trail. Go left and hike for 2.1 km to the spur trail that heads to the summit. The views are excellent, but it’s a bit of a scramble to get up here.

    If you’re satisfied with your trip and not looking for an extension, retrace your steps back to the parking lot (or pitch your tent and settle in!).
