If you like (sometimes steep) inclined usually unpaved rocky, trail and then this is for you. When you start your loop if you go to the right it’s straight up a steep hill that’s rocky and will get you to the top quicker. The other option is to the left and it’s a longer route with some zigzagging mostly leveled but with steep inclines and stairs. I recommend taking the extra loop known as the eucalyptus trail. I believe it’s an additional .3 miles. The view is very lovely. The sign is nice. Overall I would recommend.

Very nice for a brisk hike, the zig zag portion is upgraded, making the area more accessible and easier to walk through. Caution with some steps (they are very high and low). Overall beautiful !

Nice hike. The hike has a big change in elevation. Parts are very steep. Hiking shoes are best, but can get away with wearing good walking shoes. Nice views. I was there on a Friday afternoon. Not many people there.

How fun to hike this hill with the giant letters you've been seeing for years. Steep ascent in the beginning, then a steep descent in the middle, leading through a surprisingly varied environment for such a small space. Nice little hike.

Good trail up to the flag, the letters trail is very steep and slippery but fun I went up three different ways to try them all. Then I went across it went up to San Bruno Mountain and that was great but once I got to the radio towers I continued on West and let me tell you that Shell peters out despite showing something on AllTrails and they became terrible with the final climb over a tall chain-link fence so I think maybe it goes north and down from the radio towers but safer to go back east

Dog owners be warned; I took my dog along with me on a hike here today and came home to find that he had 3 ticks on him! All three were different sizes, much like a small beetle. Tread with caution if you bring your dogs and make sure you check their fur thoroughly after. It felt like a small bump and when I moved the fur, I saw the tick’s legs move. Other than that, it was a nice scenic hike.

Half of my life, I have driven by the sign “ South San Francisco The Industry City “and I have never thought to hike up there. So I did ....I was here on 6/12/20. It was not difficult to find parking. It has two ways to get up and down. My way up was very rough with some areas have small grainy gravel that make it slippery terrain. I came down by stairs and hiking around those letters. It is very steep, super fun, and pretty rough,if you don’t have right shoes. This is not like Hollywood sign. I couldn’t able to take a picture the whole sign in the background while I was on the trail. But it is outstanding view of south San Francisco when I got up to the top,and what fun than sitting on the big letter S :). My letter “S”is standing for SOUTH SAN FRANCISCO. Now your turn to choose your own letter. Happy hike folks.

Pretty steep ascent if you take the stairs. Definitely not "easy." Took me 40+ minutes for 1.2 miles.

Love this trail for a quick hike to an amazing view and a great workout! It’s never too crowded and I love bringing my pup. I find myself coming back to this trail again and again— it’s great!

This is a perfect hike if you are looking to get out of the hotel while on a work trip. Close to SFO and a fairly easy climb with a nice view.

Short trail with some elevation gain. WATCH OUT FOR TICKS. I've had some on me every time I've taken this trail in the Spring.

Short but used to work nearby and walked form the Terminal Produce Market and through town and up this trail a couple of times out of curiosity. I had seen the sign for years so I walked up to it...
