Okay, so here is the clearest directions I can give to the entrance. Head towards the clubhouse or venue where it looks like people can hold receptions. Go down the concrete driveway & keep going straight until you see a little sign that says "Callippe Trail" & it states a bunch of rules for the trail. I took the trail to the right, I didn't see the trail on the left until I was walking back. The trail has certain spots where you are hiking right by the holes so you have to be extra quiet if that's the case. There are shady parts of the trails so it isn't too bad. The trail is enough for a one person single file line, so if you're going to hike with someone, they will be either behind you or in front of you. The trail ends at the entrance of a neighborhood, it's weird. I was so confused. I just turned around & went back to where I was parked. I guess you're walking on the sidewalk half the time? I don't know, still confused. I'll be back, just to see what the other trail has to offer :)

There is a short portion of the trail that takes you through a neat area that is completely away from the golf course. There was a stream and small pools of water that were a nice sight after some rain. The trail is relatively easy and we did a loop that takes us 70% on a dirt path and 30% up the paved road that we drove up to get to the parking lot. Directions: You will drive up a single paved road that has houses to your right and left. If you entered the address found on this Yelp page, you will need to keep driving to the end of the road. At some point, you will reach a parking lot that is designated for the clubhouse. We parked in the parking lot. If you are standing in the middle of this parking lot facing the entrance of the clubhouse, you will want to go towards your 7 o'clock to a paved path that looks like it's for golf carts. Once you are down, make a left towards the hills away from the golf course. There will be a trail you can take on the left and another on the right if you keep walking. We took the one on the right that took us clockwise around the golf course.

"Green Rolling Hills with Lots of Cows--Most Friendly but one Looked at me with Menacing Eyes."…read more I parked at the summit, and took the trail north. It's about 3 miles if you go all the way to the driving range at Bridges Golf Course. At that point the trail peters out. It looks like they are constructing a new trailhead there. The trail is open, so don't count on any shade in the summer. It's pretty much green hills, with a compacted dirt trail. Fortunately, it's not rutted. I found the hike mildly interesting, but honestly, nothing special. Near the golf course practice center, I saw a lot of range balls on the ground. I was tempted to take them, but I threw most of them back onto the range. I'm pretty sure I did not hit anyone, but a few times I heard some klunks, followed by shouts. I wasn't sure what that meant. They might have been mad that I still had 2 golf balls in my jacket. I did not notice I had borrowed some golf balls until I was pretty far away. These trails are good for beginner hikers, since there aren't any wild animals around. I'm pretty sure there aren't any rattlesnakes or mountain lions. But if there are, I did not see them. And even if I did see any, I had some golf balls I could throw at them. The only wild animals are herds of cows. And there are lots of them! At one point I had to go way around a huge herd. I'm not really afraid of cows, but one kept looking at me with menacing eyes and did not budge from the trail. I was afraid of that one. Could it be a boy cow? I was afraid to get close to find out, so I honestly don't know if it was a boy or girl cow. But he or she looked mean. The whole time I went around the cows I kept saying pleasant things like, "Hi Susie," or "Hi Betsy, how are you?" I'm pretty sure they knew I was a friendly man. I was surprised they knew English. So over all, a pleasant hike. Nothing really special, but plenty of parking makes this a convenient location. The incline is really not too steep, so most hikers will find this an easy hike. For yelpers who are geocachers, there are plenty of geocaches on this trail. I put out about 8 new ones, so there will be lots to find. Keep in mind that there really aren't any facilities such as restrooms or drinking faucets. On the other hand, it's really not a very long hike. Just watch out for that cow with the mean looking eyes.

"Scary Alligator (or was it a Crocodile?)"…read more This open space and trail is part of the East Bay Park system. It is definitely NOT the crown jewel of their park system. For a long time, it was just a dirty old parking lot and a poorly maintained trail. The big old parking lot is still there, but there are some nice additions behind that area. There's a good-sized parking lot off Tassajara. From this point, the park really doesn't look like much. Well, you're about half right. There is a trail that leads out of the park, and if you go left you join up with another paved trail, sort of like the Iron Horse Trail. This trail is well maintained and looks quite new. If you take the trail out of the rear parking lot and go right, a trail continues next to the US government property for about a half mile or so, then just sort of peters out. There seems to be a homeless person living near this area, next to the creek, close to the US government fencing. I started to go underneath a big oak tree, then spotted some strange looking pieces of trash. I did not go any further. There is a new, well-designed bridge crossing over the creek. Believe it or not, the bridge is actually a site worth seeing--beautiful woodwork along the top edges of the bridge. You can see the giant concrete pieces from an old bridge. If anyone has a photo of the old bridge, please post. The only photo I have shows it in big pieces. There aren't many facilities in this park. There is a big outhouse in the dirt parking lot. That's about it. Oh yes, here's the rest of the story: Near the old parking lot, there are some wood piles. One big log looks like an alligator snout. I admit I jumped when I first saw it. Then, I realized that this area probably doesn't have many alligators. A friend of mine explains that seeing animals in nature is a sign of spiritual wisdom. I'm sure he's right. Check out the alligator photo I posted. Scary, huh?
