OverviewOften overlooked because of its proximity to the ever-popular Mount Si, Teneriffe makes for a great training hike or snowshoe outing. With a few different ways to make it to the rocky summit block, you are pretty much assured solitude no matter which way you go.
The main trail follows a series of logging roads and steep trails from a small school bus turnaround east of the Mount Si trailhead (960') for nearly 7 miles, switchbacking up to a section of clearcut (3200') between the summits of both Si and Teneriffe. From there, the road cuts east to a 4200' saddle, and then another mile to the summit (4788'). A more strenuous and challenging (and fun) scramble route follows a boot track up the SW ridge of the mountain, passing a beautiful (but probably somewhat seasonal) Kamikaze Falls.
The views from the summit look down into the Middle Fork and Snoqualmie valleys. Rainier and the usual cast of Cascade peaks are well represented.
Getting ThereGo east from Seattle on I-90 and take Exit 31 to North Bend, continuing east on North Bend Way (the main drag through town). In a little less than a mile, turn left on Mount Si Road. Drive approximately 1.2 miles past the Mount Si trailhead to a school bus turnaround. On the left is a gated forest road. Park here, but don't block the gate or the turnaround, as you will more than likely get towed.
Red TapeNo permits required, but remember the mountain is in the Mount Si Natural Resources Conservation Area, and subject to the rules and all - leave no trace, no overnight camping, careful with the flora and fauna, etc...
The NRCA was established in 1987 by the state legislature to protect outstanding geologic features, examples of old-growth forest, wildflower communities, and wildlife habitat. The 9,560 acres are managed by The Washington Department of Natural Resources (DNR), and include four mountain peaks – Mount Si, Mount Teneriffe, Green Mountain, and Little Si..
When To ClimbThe mountain is a year-round option, but care should be exercised in the winter of course. Snowshoe ascents up the main trail are common, but there are photos out there of a pretty hefty summit cornice. Just use common sense and check conditions (weather and avy) before you go.
CampingNo camping is allowed in the Mount Si Natural Resources Conservation Area. There are however, a handful of options farther east down the freeway and up into the Middle Fork Snoqualmie area.
Mountain ConditionsRattlesnake Mountain Weather has a live Mount Si cam and a pretty detailed site that gives the current conditions on the other side of the valley from Teneriffe.
If you plan on ascending during the winter or spring, take care to note avalanche conditions and make the appropriate decisions before heading out.
