Are you interested in birds? If so, you may want to check out Lake Hodges located in Southern California. Right now is the perfect time to take a short hike to see the Grebes nesting on the lake.
Grebes build large nests at water level on the sticks and branches that are protruding from the water. It is quite a sight to see. In-between the sticks there are lots of nesting birds. My son and I were lucky enough to see one of the birds take a break from the nest and go for a swim, exposing a couple of yellow eggs. Of course the mommy did not go far from the nest and kept swimming close to check on the eggs.
It is an easy walk from the gravel parking lot to the Pedestrian Suspension Bridge where you can view the Grebes nesting. Once on the bridge just look west (away from the freeway) and you will see the nests. I highly recommended that you bring binoculars to view the birds. You can also see them by zooming in with your camera. Without binoculars or a camera you will not be able to see the birds in detail. Also, be sure to bring water. Even though it is a short walk, Escondido gets very hot depending on the time of day you are there.
Besides viewing the Grebes, Lake Hodges offers other activities as well. You can bring your mountain bikes or hike on the many trails around the lake. If you walk to the end of the bridge and turn left, there is a nice hike to a stream and then back around past the lake. A drive to the other side of the lake would also allow you to rent kayaks, which my family and I did one year.
To get to the Pedestrian Suspension Bridge to view the Grebes, take exit 26 W. Bernardo Drive/Pomerado Road off I-15 in San Diego, CA. Head left (West), pass the bridge, and park in the gravel lot on your right off West Bernardo Drive. There is a pathed bike/walking path from the lot to the bridge.
