Starting from the main Mount Si lot I made a loop by taking the main line up Mount Si, then east on the top part of the Talus loop trail, followed by the short connector to the Mount Teneriffe trail.  Then I followed this road-trail back down until I picked up the Roaring Creek trail west.  Followed that back to the main line then back down to my car.  Some where between four and five miles.

Things to know.  Driving into the main lot was no issue but watch out for the two growing potholes on the way out.  It's been a while since I have been up the Mount Si main line and starting the loop from here means all the elevation is gained in the first mile and a half.  That's around a not too shabby 1000ft/mile and more huffy than I like.  It's always worth going beyond the Talus loop junction to visit the big trees of Snag Flat, felt like meeting up with old friends.  Before the talus slope the Talus loop trail is much narrower with some loose rock tread, think goat track.  I already had my poles out which kept me from a couple of ankle turners.  The talus slope is the only view of the hike but it's expansive.  The Mount Teneriffe trail is a road-trail never a favorite, still more road than trail.  The Roaring Creek trail is an absolute gem.  First time for me on this section so the waterfall was a surprise and the tread wide and smooth.  Very little elevation loss gain so you don't need to watch your feet.  I found it utterly charming.  If you like forest bathing you will love this section.

So, if I were doing this again I'd start at the paved Mount Teneriffe lot (so much nicer than the main Si lot) and then hike the road-trail (that section is actually pretty nice or at least easy) to the Roaring Creek junction.  Then I'd follow that to the Mount Si main line up to the Talus loop, around the whole loop then back the other way on the Roaring Creek.  I hope that makes sense, if you look at the picture map it should.  Longer but lovelier, and you get to do Roaring Creek in both directions.

We had planned to hike the standard route to the falls via the Teneriffe trail, however the lot was closed(at 10 am). So we headed to the Mount Si lot to take a different route. Not entirely sure why the lot was closed, as it was free of snow. We ended up making a loop so came out at the Teneriffe lot(more later in report).

The bathrooms at mount Si are open, but the women's side is out of TP. One bathroom at the Teneriffe lot is open, but it has nice TP.

Wasn't going to let a closed gate ruin the plans to see this waterfall, so we took the mount Si trail up for the first half mile, then turned onto the Roaring Creek Trail, which links up to the Mount Teneriffe trail. It added mileage, but was well worth it.

There are some blowdowns on the mount Si trail, a few maples fell during the storms, some are clear, others are not. None are big, or too bad getting over though. Someone was already coming through with a saw taking care of some. Thank you!

The Roaring creek trail was lovely, we didn't see anyone else on it, and there are multiple bridges and small waterfalls. Really glad we ended up taking this route.

The old forest road section of the Teneriffe trail is easy, and had some small peek-a-boo views. There is some snow and ice on the lower part of the Teneriffe trail, it isn't on the upper parts, so it's not so bad, but the compact ice is SLICK.

After the turn up the falls trail it gets steeper and the terrain gets rockier. The switchbacks are tight, but nothing too steep. Partway up this section the view opens up for a great view of the valley and surrounding mountains. Wasn't expecting any real views on their trail, so that was a nice surprise.

There are two viewpoints for the falls, the upper and lower. We went to the lower, and that was pretty cool(but the upper is better). The final push to the upper falls is the steepest, but again, not too bad.

This waterfall is way bigger than it appears in pictures. I was really impressed. Waterfalls are usually not my thing, but this one is worth seeing. You can get right up close to it. But be careful as the rocks are extremely slippery, and there are many places where a very bad fall could occur.

Pictures really don't do this waterfall justice, I was expecting it to be smaller and less exciting based on what I'd seen online. If you like waterfalls definitely check this out!

One our way back down we decided to cut some mileage off and take the Teneriffe trail back down to the Teneriffe lot. It was still locked at 3:15 pm. Then we walked the road for the half mile or so back to the Si parking lot.

Overall a very cool waterfall, and a slightly longer venture, but the unexpected beauty of the forest delivered. Hopefully the lot opens up more in the future.

Hiked from the Mount Si parking lot up mount Si, then did the crossover to the teneriffe Trail, down to Roaring Creek trail and looped back to the parking lot.

The road to the parking lot is paved. The parking lot itself is full of potholes, but manageable. This is a Saturday with no rain in the forecast and the lot was not full at 10 am.

Did not encounter any snow on the trail. The trail has been improved over earlier this year.

I did note that the crossover trail had more overgrowth than in past years.

I didn't have much time and chose this on a whim just to get a quick workout. Wish I could have stated a bit earlier. Parked at Mt. Si trailhead where the bathrooms smell very pungent. I only saw a few people before turning onto Roaring Creek Trail and no one after that all hike.

I was surprised to see Teneriffe Falls has dwindled down to a small trickle. So if you were thinking of hiking there to see a waterfall, definitely go elsewhere. A section of lower Kamikaze Trail has a lot of loose rock. More so than I remember.

I seem to struggle a bit with steep climbs like this in the heat. It felt great to get to the top and see the beautiful colors on the horizon. Windy up top, didn't notice any bugs. Had a tough run down.

My Friday trail run was as follows: Mount Teneriffe Falls, back down to TH --> Mount Teneriffe trail to Roaring Creek to Mount Si trail --> Summit of Mount Si --> Connector Trail --> down Mount Teneriffe to TH (about 15.5 miles). I got to the Mount Teneriffe parking lot at about 8:30am and there were only 2 other cars, probably because it was Friday and lots of rain was in the forecast. I couldn't get to the falls because the trail turned into a literal waterfall - i was confused and thought I'd had reached the falls but it was just a washed over trail (see photo). The rest of the trails were great, a few stream crossings but nothing too serious. The mud wasn't nearly as bad as the weekend prior due to a more dry weather week. I saw a good amount of people on Mount Si trail but really nothing compared to a weekend day. Unfortunately, no view at the summit today. No snow on the trail, even on connector. The way down Mount Teneriffe after the connector trail i saw literally 0 people until close to the TH. I also highly recommend roaring creek trail - it's so gorgeous, quiet and GREEN! Luckily, it didn't rain a drop on me the whole time and started raining the second I got back to my car! When I returned to my car about 4 hours later, the lot was barely half full. Happy hiking.
