Mount Teneriffe


Day Hike - Mount Teneriffe

This day hike is Mt. Si from the less-traveled backside. We'll go up the Teneriffe trail to the back of haystack rock. For a nice loop we'll come back down the main Mt. Si trail to the Talus Loop trail and back to the Teneriffe trailhead parking lot.

COVID-19: Learn about our most up-to-date guidance for participants and leaders on our COVID-19 Response page. All participants and leaders must agree to the COVID-19 Code of Conduct before participating in this Mountaineers activity.

  • High Point Elevation: 4,043 ft

We will meet at the Mount Teneriffe Trailhead at 9:00 a.m. Directions can be found on Google Maps (search Mount Teneriffe Trailhead).  If you've been to the Mt. Si parking area before, the Mount Teneriffe parking area is further down the same road, on the left. Nice parking lot and new bathrooms.  A Discover Pass is needed. 

I will meet the group at the trailhead. Anyone who wants to carpool should do so with the goal of being at the trailhead and ready to hike at 9:00. 

This is a moderately challenging hike on the lesser-traveled backside of Mt. Si. If you've hiked Mt. Si before, this is a nice change of scenery with a similar grade. Please note that this is a 10 mile hike, so please be conditioned to do this distance and elevation gain at a moderate pace. We will take short breaks when needed for clothing adjustment and, weather permitting, stop for lunch behind haystack rock.  We will not be climbing up haystack rock itself.

As we get near the top of this route, the weather can get very chilly. Please bring extra clothing, hat, mittens, etc., in addition to the 10 essentials. Given our colder weather lately, I recommend that you bring microspikes in case we encounter snow.  Most folks will also want trekking poles on this route. 

I will send out a weather update two days before the hike.
