This is a hard loop trail to Mount Si in Mount Si Natural Resources Conservation Area.
We did not see the turn off for teneriffe falls. This trail goes by Teneriffe Falls.
Getting Started
Park at mt si parking area. We arrived at 5am and the gate at the new parking area for teneriffe was closed.
Taking Children
I wouldn't suggest this trail for kids as it is a long hike unless they are experienced. There is also a bunch of snow on the connector trail on the top. As well as boulder fields on si.

I started early in the cool morning up the Mount Si Trailhead. Had the trail to myself for most of the way up and only six coming down. I’m at the base of the haystack in about 2 hours. I came all this way, the weather is perfect, sunny and clear, not hot today but there is a stiff wind blowing. I climb the haystack. It’s slow going making a safe ascent. The views are worth the effort. Going down the haystack by retracing my ascent. I found was easier going feet first on my behind holding on with my hands. Bring garden gloves!
My return down I took the Si Teneriffe Connector trail eastbound to the Mount Teneriffe Trail. Turned west onto the Talus Loop Trail back onto the Mount Si Trail. It’s a nice loop.

Hiked Monday 4/22/19 saw over 50 people on the trail mostly all on descent, saw 2 people on the teneriffe/si connector trail on top and 3 people at the very top where it seems the technical climb is. Started at 5am. 9.5 miles in 7.07 hrs. Elevation gain 3459. Tried to park at teneriffe parking area, but the gates were closed there when we arrived at 5am so we parked at Mt. Si which was open. Bathrooms were really gross and on the other side of the trees torwards the trail. Only 3 other cars in the lot when we arrived. We Started on Mt Si trail, then took the first talus loop trail, then took teneriffe trail, then took the teneriffe/Mt. Si connector trail ( patchy snow at first, turns to deep slippery snow, microspikes were very helpful. Rocks in the creek crossings were also slippery.) Teneriffe was a long steady climb, Mt Si trail was more on the steep side. Teneriffe to Si connector had little to no views. Took Si on the way down. On Si trail there is a boulder field. Had a great time. After this trail we hiked Rattlesnake Ledge. Parking lot was full in the first couple areas on the way out. I think there are 4 or 5 big parking areas at Si. Picked up 4 bags of poo and trash at Si. This is a great trail, but be prepared for the climb.
