Upcoming Open Space Events

RangerRangers help groups make new discoveries. Sometimes the tiny things are fascinating.

Nature Programs
LARPD offers exciting ranger-led adventures almost every weekend. These programs are great for families and individuals. Most do not require advance registration but some do (please check descriptions). Call the ranger office at 925-960-2400 with any questions. 

Keep an eye out all year for the District’s 70 Miles for 70 Years Challenge. As LARPD celebrates 70 years of operation in 2017, the Open Space staff are offering a special challenge to encourage participation in nature programs. The Challenge will be a series of specially designated walks, hikes and bike rides of ranger-led programs for participants to log miles. Those who earn at least 50 miles will receive a 2018 Sycamore Grove calendar. Anyone who logs 70 miles will also earn a 2018 Sycamore Grove parking pass. And the person with the most miles at the end of the Challenge will receive admission for two on a regularly scheduled guided hike of Brushy Peak Regional Preserve. Look for the 70 Miles for 70 Years Challenge programs each month in 2017.

An Early Morning Walk in the Park – 70 Miles for 70 Years Challenge (RSVP)

Saturday, July 22                                                                    8 a.m.

The park in the early morning is often less crowded and more serene than at other times – it’s also a lot cooler. Come on out for an early morning jaunt and beat the crowds and the heat. Many of the critters that call the park home will be starting their day and, if luck works out, the group might see some of the night shift animals on their way home. Bring a camera or binoculars if you like. Please RSVP by calling 925-960-2400 or emailing Participants will earn 2.5 miles toward the 70 Miles for 70 Years Challenge.

Creekside Storytime

Sunday, July 23                                                                      10 a.m.

LARPD rangers and Livermore Public Library librarians will entertain families with children's books about nature and wildlife.

Participants are encouraged to wear closed-toed shoes and clothing that can get wet during the creek exploration. Please email and ask for directions to our special meeting location – it's not normally open to the public. For other questions, please call the Library at 925-373-5504.

Summer Star Walk

Saturday, July 29                                                                    8:30 pm

The warm evenings of mid-summer are the best time to go for a star walk. The crescent moon in the western sky should be dim enough that to see Delta Aquarid meteors. Participants will stop along the way for some star stories and possibly even see some owls. The hike will be approximately 3 miles, on mostly unpaved trails.

Evening Bird Walk

Saturday, Aug. 5                                                                     6:30 p.m.

This program offers a chance to mix it up for this month’s bird walk. Instead of heading out in the early morning, wait until the birds go out for dinner. Last summer delivered some rare (for Sycamore Grove Park) species in the Nature Area, so that's where this program will be. Due to possible extreme temperatures, please RSVP to Ranger Patti will then be able to contact you in advance if the program needs to be canceled due to a park fire weather closure and also give directions to the Nature Area Entrance.

Young Scientists Creek Survey

Saturday, Aug. 26                                                                   10 a.m.

All ages are welcome, but trails are dirt and gravel so strollers are not recommended. If you have not been to the Nature Area Entrance before, please email for directions to this special area.
