We just drove through the pass, but there were many runners and cyclists there.

It's a pretty tight, two lane road without much of a shoulder. I would go single file.

Guardsman Pass is a paved two lane street that runs through the mountains. I am not aware of restrictions if there are any but I would think that it would be dangerous to use a side by side because of the cars on the road.

Yes plenty of them. There are not any restaurants if that is your question. I would suggest stopping by Legers sandwiches or even better uptown fare for a lunch to go. These are both in Park City. Once you are in Guardsmans pass you will see several spots for a great picnic.

I don’t think they have a scheduled time. It depends upon the snowpack and melt.

Yes

Yes. They only close it by winter.

Papa TOny's answer is correct. Need to call Breckenridge Chamber of Commerce or Police.

It is a beautiful location. I would imagine if you asked the Huber City people. You would have to truck everything up there. I would only attempt this in the summer.

Paved but very narrow in spots. On the way to Brighton (past the pass) there is one curve that was pretty damaged (with graded gravel surface) and only passable by one vehicle at a time. You just have to watch for oncoming traffic and take turns. This spot was only about 100 feet or so long and passable in a regular passenger car. The Brighton route takes you through nice national forest scenery all the way down to Salt Lake City (eventually running into 215 beltway) Alternative route is to go toward Midway into Heber Valley and hit the main highway (US 40) back to Park City via Kearns Blvd or I-80.
