What you need to know for the day of Kosi

11 Mar 2024

Before you leave home

Check the weather and come prepared

The weather in Thredbo is highly changeable on any given day. Please check the weather forecast in advance and come prepared for all conditions.  We recommend sturdy walking boots or shoes that have been worn in, waterproof jacket, light woollen jumper or fleece, thermal top, gloves, a warm hat, sunglasses and sunscreen. Remember to also pack at least one litre of water, lunch, snacks and any medication you may need.

The Eagles Nest café positioned at the top of the chairlifts will be open for light refreshments from 9.30 am on both mornings.

Expect trail upgrades 

The NSW National Parks and Wildlife Service (NPWS) is upgrading the Mount Kosciuszko Summit walk in Kosciuszko National Park to repair flood damage, make the track more resilient to future weather events and improve accessibility to the popular Mount Kosciuszko summit. Please take the time to read the attached document regarding the upgrades and what to expect on the trail.

Download the Emergency Plus App
Please download the Emergency Plus App in the event there is an accident within your group. For assistance on the day, call Ski Patrol on 6459 4147 with coordinates of your location from the app.

Telstra will be upgrading its mobile network around Thredbo with work to take please over 9 days commencing 15/03/2024. Your mobile service may be impacted at various times during this period.

Friday 15 and Saturday 16 March – morning

Wet weather plans 
If the weather is inclement and Kosi Challenge is unable to proceed (due to snow, rain, wind or thunderstorms) Thredbo Management will cancel the chairlift and trekking in Kosciusko National Park. You will receive an SMS by 6.30am on the morning of your climb with further instructions and alternate plans.

Arrival and registration
Registration will be setup outside the Thredbo Alpine Hotel Bar. It will be clearly identifiable with RCA signage. You will need to arrive and register 15 minutes before your selected time wave. This will give you enough time to check-in, grab your complimentary RARE merchandise and chairlift/gondola ticket included in your registration, and join your group at the marshalling area.

Any questions on the day can be directed to an RCA team member wearing an orange branded RARE vest.

Chairlift ticket and complimentary RARE merchandise

Thredbo will only allow you to access the chairlift if you have a pass.

All passes will be handed out at the registration desk on the morning of your climb, along with your dedication flag and complimentary RARE branded cap.

Please note that your chairlift ticket also includes use of the gondola. 

In Honour Wall

An 'In Honour' wall will be on display for those who are climbing in honour of a loved one. If you have not submitted a photo prior to the event, please bring one along to add to the wall. Permanent markers will be available for you to leave a personal message on the wall if you wish.

Registered participants only

Your safety and wellbeing at Kosi is our number one priority. Attendance numbers are strictly limited by NSW National Parks. RCA reserves the right to decline entry to any persons who risk jeopardising the safety of the event, including those who have not registered for an in-person ticket.

During the climb

Safety and incidents
Please note there is a time limit of 15 minutes once you reach the summit. No more than 100 people can be on the summit at any one time. 

Marshals, guides, RCA staff and medics will be wearing orange high vis RARE vests. Please alert them to any incidents. They are equipped to call for assistance if needed.

Please do not run along metal walkways. This can be dangerous, especially in wet weather

Restrooms and rubbish
There are four toilet locations: inside the Thredbo Alpine Hotel Bar, at Valley terminal, at the Eagles Nest café, and just before the summit climb on Kosi.

Please do not leave rubbish behind in our beautiful National Park.
