The Refuge at Laguna Colorada is undoubtedly the best lodging for many scores of miles. One could ask for more salubrious facilities but if you've got this far, do you need them? No. This is about location not room-service.
Our room slept 8 on concrete pads with mattresses on top. The cardboard under the mattress goes a little way to relieving the chilling effect of the base but a sleeping bag is recommended. The fact that the beds are only 15 inches apart helps keep the room temperature above freezing most of the year. The rooms are unisex but most people added clothes to go to bed so this was not an issue. Ear plugs were a great asset.
Our block of about 40 beds shared 3 toilets, one with a door and one with a seat. All could be made to flush with practice. A wash basin with working tap provided a steady trickle of cold water. We also had a hot water shower (quite cheap, coins needed). The fact it was used by visitors from other blocks suggest this is not provided in all blocks. Take a torch to find the ablutions after dark.
Guides and cooks have access to simple kitchen facilities. Tables along the main passageway provide a communal dining area. There is room enough to move the tables to a drier area when frost-melt drips through the roofing.
An electric socket and extension lead were provided centrally so visitors could recharge batteries although the generator is only run for a few our each evening so queues can develop.
There is ample parking (acres of desert on the door step).
The views of the surrounding snow-capped mountains and the magnificent Laguna Colorada made our stay truly memorable.
