You have had some really good replies so far.

In the mountains realty could mean anything

• I’ve done winter camping in snow - in the mountains
• I’ve done summer camping (in snow, shit can go sideways) - in the mountains
• I’ve done subtropical camping - in the mountains
• I’ve done temperate camping - in the mountains
• I’ve done 90 mph wind camping - in the mountains
• I’ve also done some absolutely drop dead breathtaking camping in the mountains

As others have said, beperpaired for it to be colder than you expect.

Are you walking / hiking in, or car?

Enjoy it
