How to Reserve

1. Reserve the Group Campsite

Call Reserve America at
1-800-444-7275 or visit the Reserve America web site at www.reserveamerica.com
Be sure to reserve the Group Camp, not the family camp.

Most Friday and Saturday nights at the Group Campsite are very popular, and get reserved up to seven months in advance. See the Reserve America website
for information about the earliest possible time to make a reservation for a specific date.

2. Reserve the Observatory

Call the Observatory at
707-833-6979 to leave a
message with your name, phone number, preferred dates,
and a brief description
of your group.

You will receive a call back to discuss the reservation, plan any special program features for your group, and take your credit card information for the reservation.

The Observatory should be reserved at least two weeks in advance of the date of your event.

Cancellations must be made at least 48 hours prior to the event.

In the event of a cancellation, a rain check will be provided if weather is likely to make observing impossible. Observatory docents provide a program which is entertaining and informative regardless of weather conditions.

Refunds are not provided.

Observatory rentals are limited to private events to which the general public is not invited.

If you are interested in conducting a public event at the observatory, please leave a message with a description of the proposed event and your name, phone number, and preferred dates.


Best Times

The dates near the New Moon are very popular (when skies are darkest and astronomical objects aren't washed out by moonlight).

We also have groups reserve us to specifically observe the Moon during quarter phases.



Observatory Fee: $165

A large group campground is located adjacent to the Observatory.
It has a spitted barbeque pit, picnic tables for 50 guests, an area for tents, and adjacent parking large enough to accommodate RVs.
The PlanetWalk and other hiking trails are nearby.

Enjoy the quiet beauty of Sugarloaf Ridge State Park during the day and spend quality time with RFO telescopes until late at night—without having to drive home.

"You guys were awesome! Thank you so much. The kids not only had a lot of fun, but they learned a lot, too....That observatory really is a key to opening those young minds. Thank you."
