Idaho Hwy 20 Mt Home to Arco?

[Finally_Time]

I see from the map there are two ways to get from I-84 to Arco. ID from Mt. Home; Hwy 20 which looks like it climbs over a twisty pass or continue on I-84 then take Hwy26, (about 11 miles longer) I'm in a 28+ foot motorhome towing a car. I'm not crazy about two lane roads over passes. Recommendations?

Thanks for the info. I took Hwy 26 I just didn't feel like more twisty mountains, even if it is only for a short stretch. H-26 was ok except for two or three miles very rough road; felt like the expansion bands on the old concrete highways.

Thanks for the question and answers. I'm also going from Mtn Home to Craters of the Moon National Monument in late July. Was wondering about Hwy 20. Good to know I can go either route.

We've driven both towing. Both are good. Hwy 20 climbs with some turns, but nothing major and is a scenic route. Hwy 26 is good too, more stops because of going through small farming communities.

I took 26 a few years ago. Good road.

26 is a much easier drive than 20; neither is bad. 20 is just more climbing and tighter curves.

I've never taken 26, but my guess is it goes through congested farming community & the road is probably narrower than Hwy 20.

I've been over 20 many times & it is a good hwy & not your typical 2 lane. It's also as stated above very open & not a lot of traffic.

Sorry- didn't specify- I took highway 20 off the 84. It's a little winding at first, but nothing to be nervous about. I thought it was a beautiful drive.

I drove it last year with my Tundra and 21 foot trailer. No problems, almost no traffic. You can see for miles.
