4/5 hike and I would rate the difficulty as 2 out of 5 difficulty. At the entrance, the sign says 2.3 miles to the falls, but I think this if off. You will come across a San B sign about 2 miles in, I think this is the indicator for the 2.3 miles because the falls are MUCH further up and I would say that the hike to the falls is between 2.5 to 3 miles, with a RT of probably 6 miles.
Let's start off with the directions:
I would not advise taking a car that is NOT 4 wheel drive up to the sand parking lot as indicated in the previous reviews. There is another sand parking lot probably 0.5 miles after you cross the small bridge mentioned in Jon K's post. It's roughly 3 miles from here to the entrance with the sign and the other parking lot.
Keep in mind, Third Stream Falls is NOT clearly marked, you have to go off trail to get to it. Also, the actually trail follows the riverbed most of the way. If you think you are about 3 miles in and still on the trail but don't hear the water anymore, you might have passed it.
Jon K below probably has the best directions so I advise you follow his. The problem is, this is the mountains so his directions aren't perfect. The main thing you have to keep in mind is once you cross the riverbed mentioned in Jon K's post (which is dry of course), stay to your left of it and continue hiking up. Keep an eye out on your left side. You should soon notice that the left side gets taller and taller and eventually looks like 100ft cliffs when you look up. THIS IS YOUR BEST INDICATOR that you are almost at the entrance to the falls. The left side will start to open up and once it does, follow it up and you will be at the falls. You will have to climb up lots of rocks but it's not big or dangerous. As long as you stay to the left of the riverbed you can't miss this 100ft wall of rocks entrance. There's are only 2 directions, one is going left and following it to the falls and the other is continuing up the riverbed.
The actual hike:
This hike is a GREAT workout for your calves! Went with a group of 7 people. We started at the very bottom parking lot so the RT ended up being probably 12 miles or so (3 miles up the bottom parking lot to the actual entrance, roughly 3 miles from the entrance to the falls since we actually passed it, and the 6 miles back down all the way). Keep in mind you will be hiking up hill pretty much the whole way there, but it's a gradual incline to say the least. Bring lots of water because you will be in the sun most of way up. The trail is clearly marked up until you cross the riverbed to find the falls. The scenery is mediocre, but a hike is a hike, so it's still great nonetheless. There are a lot of bugs, most gnats, but there will probably eventually be mosquito so maybe bring some bug spray. You can definitely bring a water filter if you want, there is plenty of water you can grab that come off the rocks and what not (not the stagnant water of course). The actually falls isn't huge, but it's nice sight and the pool of water is about thigh deep (I'm 5'4) and it the water is REALLY cold. If you wish to stick around and enjoy the water, I advise to start the hike before 11am so you can enjoy the warm weather and the cold water.
The hike RT totaled to be about 6 including the time we spent hanging out at the falls. Would I do this again? Yes, start early though! We started at around noon and didnt get back to our car till about 6pm or so. Good for groups? Yes. read more
