The club holds regular observing nights for its members at the Linden Observatory site in the Blue Mountains.

Visitor Information

Visitors may attend our Club Observing Nights at Linden but must book at least 3 days before the intended observing night. Club Only Observing Nights at Linden are reserved for club members only. Due to basic and limited facilities, we can only cater to a small number of visitors. This email address is being protected from spambots. You need JavaScript enabled to view it.

All visitors to the Linden site must arrive by sunset so that visitors can park safely and get an overview of the site while it is still light. On arrival, ask to see a committee member so that we know you are there. Visitors are requested to give a donation of $10 per person to the Linden Trust and WSAAG for the upkeep and improvement of the site.

We do not recommend children under the age of 12 be brought to the site. There is no lighting and there are many rock outcrops and high escarpments that create fall risks for wandering kids. All children must be supervised vigilantly by their guardians while on site. For families with children we recommend Penrith Observatory .

Visitors to Linden should wear closed-in shoes and not open sandals or thongs. Appropriate clothing should be worn as it gets quite cold at night, especially in winter. In the hotter months, you need to apply an insect repellant because of mosquitoes. As it is a dark site with uneven terrain, a red-light torch (or torch with red cellophane) is recommended when walking about the site at night. You should be aware that facilities are very primitive - outside toilets and a storage shed with sink. Bring your own refreshments.

It should be noted that members will be giving up their own observing time to show visitors around the night sky. Most of the telescopes on site are brought to the site by individual club members and are owned by those members. Visitors may look through a member's telescope only where invited to by that club member. We ask that visitors leave no later than 3 hours after sunset to allow all members to continue with their own observing.

Visitors are expected to act responsibly while on site and follow any reasonable directives given by a committee member. All visitors enter the site at “their own risk”.

If it is very cloudy, raining or windy, observing will likely be cancelled. If not sure, check with the committee before making the trip to Linden. Otherwise you may be disappointed if observing has been cancelled.

Visitors please note:

No smoking is permitted at the Linden Observatory site. This includes all grounds and buildings. No pets are to be brought onto the site as it is a wild life sanctuary.

Beames' Observatory (Dome)

The old Beames' Observatory (Dome) and its 24" telescope are not operational and only have historical value as it is impractical to use for observing. It is not open to the public.

Evans 30 inch Telescope (visitor restrictions)

Due to public risk and safety concerns, members of the public are not generally given access to the Evans 30" Telescope.

Visiting astronomers with astronomy club or professional astronomy associations are welcome to book observing times via email at This email address is being protected from spambots. You need JavaScript enabled to view it.. A booking is conditional on at least two accredited WSAAG members being available to operate the Evans 30” Telescope.

 General Directions from Sydney

From Penrith, take the Great Western Highway, to the Blue Mountains, and travel for approximately 30 minutes. A road sign for Linden appears approximately 2 km or so before the Linden turn off. A street sign for Tollgate Drive, on the left hand side of a sweeping bend, indicates the turnoff for Linden.

Tollgate Drive curves back over the Great Western Highway via a narrow bridge. Watch for oncoming traffic. After crossing the bridge, take the first turn right into Glossop Road. Travel the length of Glossop Road as the Observation Site is the last property.
