Tiger Mountain is supposed to be hikeable most of the year. We went in August and trail conditions were great!
We didn't park at the trailhead parking lot so we hiked a short distance through the forest to our destination.
I would rate this hike as medium in difficulty. My children might disagree. The climb was uphill the entire 3 miles to the top with an elevation gain of 2100 ft. which was a bit tiring for the boys. The trail however, was wide and very well maintained.
The hike through the forest was calming and peaceful and we enjoyed looking at all the scenery.
I would say this hike was a great one for the challenge, but the views at the top weren't the best I have seen. So, if you are looking for a great hike for the climb, this is a good choice. After all of the great hikes I have done with my boys, they were underwhelmed with the views at the top and my oldest son was expecting more for all of the work it took to get to there.
To get here drive I-90 east of Issaquah to Exit 20 (High Point). Go right and right again on Frontage Road (hard to see sign). You will see this sign. You can park here without a parking pass. There is a trail that leads from this spot to the actual trailhead that is .3 miles away.
If you would like to park at the trailhead, drive past this sign and follow a dirt road for less than a mile and you will reach the parking lot. A Discovery Pass is required to park here. Discovery Passes (I found out) are different than Northwest Forest Passes, so you will not be able to use your Forest pass here. They are $10 for a day pass or $30 for the year.
There are bathrooms just past the trailhead opening.
To get to the High Point just follow the West Tiger #3 signs. If you have hiked Tiger mountain, let me know what you thought. Happy Hiking!
