Shadow Cliffs Lake — Attraction in Pleasanton

This is NOT a place to go swimming. The water is cloudy and on warm days there is often signage regarding unsafe bacteria levels. I simply don’t enjoy swimming next to all the geese and duck poop. Avoid the busy Memorial Day and other long weekends where it’s so packed there’s no parking and the place is saturated with people. NOT ideal for paddle boat rental - not certain their hours but they usually closed whenever we come by. The boat and dock do not look well maintenance so I’ve had no interest in renting one to see the same view I can see from shore. I actually seldom go to human swimming and boating area - too much duck poop.

This park is excellent for dogs, hiking, running, and bird sanctuary/bird watching. We live close by and walk our dog here regularly, to her favorite doggie swimming area. The BMX bike park is great but unfortunately my children is not that adventurous so we usually just bike along Stanley. They hold the Tri for Fun here as well as many other races and events (kayaking, fishing, swimming, boating). It’s also a great place to go fishing (children under 16 does not need permit). On non event days, it’s just a nice place to chill. Although I know the appeal of being near water in summer heat, this park is definitely better in Spring and Winter (less people and safe...

If you are birder this is a must visit--especially for raptors. The beauty of this suburban area is that there are trails for cycling; walking; nature drawing; and with the recent rains fishing has returned. Yesterday we were greeted by a pair of Red-shouldered hawks who were chasing a Northern Harrier out of their hunting area. What was especially nice was seeing another birder/photographer. This was the first time we had seen this bird at this location. The local Osprey decided to fish in an area not open to the public. The staff uses the fallen trees to keep people safe and discourage bothering the wildlife. I document species of birds while my husband takes pictures. Anyone can download the Cornell Lab Merlin app and teach their young how to treat nature with kindness. We regularly spend around 6 hours walking around and it is a perfect way to be stress free. And, yesterday was no different. We happily spied a female Merlin (another rarity). There are too many species to list all the birds you hear & see. The entrance fee of $6.00 (pay with card when no one is there) is a bargain! The downside--people on speaker phone; dogs off leash; the kids who throw rocks at the wildlife; and the Livermore Airport with lots and lots of...

Dirty and unorganized place. Restrooms are smelly and unclean. Staff including security guards behavior is extremely rude and disrespectful. The place looks like super messy. 6$ parking charge is not worth of this place. Super windy and cold due to lake water. Not a good place to host parties. Not a good place to evening visit because they close by 7PM irrespective of any time. May be convenient for...
