Alien Rock and Bloc are looking forward to welcoming everyone back as from Monday 26th April 2021, provide Scottish government roadmap remains on track!

Both walls will then be open 10am to 9:30 pm Mon-Fri and 10am to 6:30 pm Sat-Sun.
Thanks for being patient during this time, we're sure everyone is super psyched to be climbing again.

Obviously there are still changes to our operation, a brief summary of which is listed below:

-Firstly. These are very trying times and we have done our best to ensure people feel safe to use our walls. However if you still feel nervous unsure or that the risk is too high
perhaps it will still be too early for you to resume indoor climbing.

-If you feel unwell have a high temp, persistant cough, lack of smell or live with someone who is self isolating then please do not come for now.

-For now pre booking at no cost is still required to ensure your entry to the wall.
2.5 hour time slots are available as detailed in booking system.
Wall shut for 30minutes between slots.
The booking system shows available spaces and how many have been booked. A very limited number of walk ins mayl be available.

As per government guidelines:

-The calculated capacity for alien rock is 28 persons

-The calculated capacity for alien bloc is 60 persons

- The booking system is in operation at both centres: this will be 2.5 hour sessions, bookable upto 2 weeks in advance.

Please note, if you are not as yet registered to climb at alien rock or alien bloc please follows the links to the registration pages first.

Please note you should only register to climb at alien rock if you know how to belay/tie in, either through experience or having completed a beginners course.

-At times queing for entry may be unavoidable so please dress appropriately.

- We are adhering to current guidelines on social distancing, with customers expected to keep 2 metres apart when using the centre.

- Hand sanitiser is available throughout both centres, and customers are encouraged to clean hands: before, regularly during and after each session.

- Masks are required in all areas of both centres. except whilst actually climbing in the climbing areas.

These items will all be subject to change at any time. We will continually monitor expert advice and overall centre operation and make changes as necessary. It's important that everyone feels comfortable and safe using the centre, and we will be doing our utmost to ensure this.

Here’s an update of how our walls are currently operating.

- All sessions still need to be booked using our booking system, link above. This seems to be working smoothly so far. If people could make sure to cancel sessions if they can’t attend: to cancel, follow the link in the email confirmation, select Ticket Options and Cancel ticket.

- Regarding the new Scottish government rule, of a maximum of six people from two households meeting socially: if people could make sure to also stick to this when visiting with or meeting others at either centre.

- Everyone should make sure to keep adhering to the 2m social distancing rule when using the centres. With cases remaining stubbornly high, we want to maintain as safe an environment as possible by sticking to these best practises, and thus avoiding any additional restrictions or future lockdowns.

- Currently we are still not running any instructor led sessions at Alien Rock; this includes beginner’s courses and any kid’s sessions. We will continue to monitor government guidance and introduce things gradually when safe to do so.

- We have a slight change to the rules regarding adult members supervising novices or U18’s. An adult member can now supervise 2 novices/U18 per session if they are all from the same household or 1 novice/U18 per session otherwise. Adult novices can only be supervised at Rock.

- Again thanks to everyone who has visited since we re-opened and got on board with all the changes to our operations. It’s been really great to see all the regulars back and lots of new faces enjoying Rock and Bloc again!


alien one combines a fantastic selection of amazing climbing surfaces that all fit ingeniously into the vaulted ceiling of the former church building.

Many of the features were hand crafted on site and are truely unique, an unusual and welcome surprise in a world that is becoming ever more franchised and "mass-produced". Your first word on entering alien one is likely to be "Wow!"

From easy slab to wildly overhanging roof there is something to inspire and challenge every climber whatever their ability and wherever they have climbed before.

To maintain long term interest and provide a variety of challenges, the majority of climbing "routes" to the top are removed, cleaned and changed around on a 4 monthly basis. There are around 200 different routes to keep you entertained.

The walls provide top-roping, leading and bouldering in one location.The 40 top-roping lines provide much of the entertainment with the rope providing protection from above.
For those climbers with more experience, the 12 overhanging lead lines provide a greater challenge, since they must clip the rope into protection points as they go.

Each line usually has three distinct colour-coded routes to the top made of individual bolted on holds. These "bolt-on" holds come in thousands of variations of shape and size from tiny fingernail sized edges through to double handed "jugs".

Climbing without a rope is available in the fully matted bouldering wall (up to 4.8 meters high).
The wall varies from vertical to 45 degrees overhanging.
The main, larger bouldering facility for alien rock is now situated nearby at alien bloc .

Before climbing, all climbers must register at reception and new climbers must fill in a registration form either in center or online. (membership is free!).

Please note you should only register to climb at alien rock if you know how to belay/tie in, either through experience or having completed a beginners course.

Sorry but due to the current covid-19 restrictions we are unable to offer any courses or kids clubs at the moment. The following information pertains to normal times.

An experienced registered climber can sign-in up to two beginners (of any age). Another option for inexperienced climbers is to attend a pre-booked beginners course. Hire equipment (boots, harness ,belay device) is also available.

All climbers under 18 years old must have a completed alien rock parental consent form.

Groups of novices (more than two per experienced climber) must be taught by a qualified instructor.

While not climbing, the reception area also provides drinks, snacks and climbing equipment for sale (in the Tiso shop).

For bus and travel information see the location page.
