Enjoy the many free Outdoor Activities on Midpeninsula Regional Open Space District preserves. All activities are led by trained volunteer docents and are free of charge. Some activities require reservations. Please refer to the Reservation Information page for full details.
For all activities, heavy rain at the activity location will cancel that activity. In the event of light rain or the threat of rain, the docent will make the decision at the designated meeting time and location.
If you have a group of 4 or more people who would like to attend a docent-led activity listed in Outdoor Activities, please contact the Docent Programs Coordinator at (650) 691-1200 to discuss in advance. Other arrangements may need to be considered for your group.
Reservations are required for certain activities.
Reservations for a given activity are only accepted within the two-week time period prior to the activity date. The maximum number of people allowed for a group reservation is four (4) people. The online reservation forms activate in the individual listings two weeks prior to the date of the activity.
--Emails and voicemails regarding activities are not monitored after hours or over the weekends, but will be processed the next business day.
--If your plans have changed after you have made a reservation and you are no longer able to attend, please let us know so that we can release your reservation to someone else.
