Bandera Mountain - Ira Spring Trail - 7.0 Miles Round-Trip

The Ira Spring Trail climbs over 3000' in just 4.0 miles to Bandera Mountain, a strenuous trek with exceptional views across the I-90 gateway to the Central Cascades. Since views are limited on the true summit, most hikers aim for the Little Bandera promontory, a rocky perch 3.5 miles from the trailhead that's only 80' below the true summit.

Here you'll enjoy amazing views straight down to Mason Lake, Lake Kulla Kulla and beyond to Mount Defiance and the Pratt River Valley:

The trail rises steadily from Ira Spring Trailhead on an old logging road before switch-backing east to Mason Creek (.8 miles : 2,575’), a tricky ford with high water. Once across it passes an old trail intersection (.9 miles : 2,675') with partial views of McClellan Butte.

At 1.6 miles the trail veers off the logging road onto singletrack and begins a steep climb through intervals of silver fir, Doulas fir, salal and vine maple. The trail passes a stand of noble firs (2.5 miles : 3,818’) before thinning with views of McClellan ButteMt. Rainier and the greater South Fork Snoqualmie Valley.

It emerges in open space and crosses a talus field on crib steps and paver stones (2.7 miles : 3,950’) to the Bandera Mountain – Mason Lake Trail split (2.9 miles : 4,190’).

Here travel steepens considerably straight up the open mountainside, gaining nearly 1000' in just over 1/2 mile without the aid of switchbacks. This challenging climb is highlighted by spectacular views of surrounding peaks and Mount Rainier.

Grades ease some through 3.2 miles (4,722’), where you can follow a faint path to the Little Bandera promontory (3.5 miles : 5,164’). Enjoy amazing views straight down to Mason Lake, Lake Kulla Kulla and beyond to Mt Defiance and the Pratt River Valley.

You may also continue .5 miles and 80' up to the true summit of Bandera Mountain (4.0 miles : 5,240'), though views are limited on this heavily wooded point.

Worth Noting

  • The Mason Creek ford at .8 miles can be difficult with high water, especially during the spring runoff.
  • Most hikers will end their trip at the open false summit of Little Bandera (5164’) since the true summit of Bandera (only 80’ higher, but a half mile further) is wooded and does not have views.
  • The open climb above the Mason Lake / Bandera junction to the top of Bandera is extremely steep – trekking poles are helpful here.
  • A fire in the 19th century burned the upper part of Bandera Mountain and the forest has still yet to recover – in its place, silver stumps and bear grass abound.
