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.
