Very scenic hike. Starts with a gradual 1000ft descent followed by an ascent about half way through. The hike is not challenging, however the trail is very scenic, with a lot of amazing panoramic views. Do not let some negative reviews discourage you. The last part of the hike does take you on a private road through a household community, but I actually enjoyed seeing all the upscale houses. No reason not to hike this trail.

First half of the trail is great, but the second half takes you on a local road which i didn't love. Would recommend instead taking the trail further east and coming back via skyline blvd trail.

San Lorenzo River is pretty. However, after crossing the river, incessant sounds of gunshot continued through Travestine Springs Trail and most of Saratoga Gap Trail. Sometimes the sounds were very close and extremely made me uncomfortable. There were lots of bugs flying around me all through the hiking. Strongly recommend to carry repellent.

This was a decent hike with some excellent overlooks. However, it doesn't mention in the description that a good portion of the hike is on pavement through a neighborhood. The rest of the hike was nice, though.

Nice trail with lots of shades. Not much elevation gain. Finished in 3 hours

Couldn't exactly figure out where this trail starts from the parking lot. Ended up going to Summit rock and back.

Hiked it Sunday July 3rd. First two thirds okay but not very challenging. Last third was unimpressive - On paved road with little shade. If you like paved road, you will like this section. We did not. Also, the local gun club provided a constant barrage of gunfire for the background soundtrack. Not a bird to be heard.

The loop is actually a triangle formed by 3 trails: down Saratoga Toll Road Trail - Travertine Springs Trail - up on Saratoga Gap Trail. The latter includes a portion on asphalt road. It's a little confusing so better take a map. Most of it is shaded by trees and with nice elevation changes. Very few people too. Great time !

We had a great time hiking the trail, but started to late. It was hot too. Bring lots of water.

I made the mistake of not knowing my start location. We ended up hiking all the way around the park in a big Loop. The map does not do a good job of showing you where you are, so I recommend using an app with the maps installed on it. It was a fantastic trip, with a waterfall. Hiking in the woods we saw a massive redwood tree. Not many people were on this part of the trail I was surprised, it was by far the largest tree in the part.
