General Description
At the end of a short hike through the Boise National Forest you will find one of Idaho's most unique hot springs. There is so much flow at Vulcan that the US Department of Energy has been salivating over it's geothermal potential for years. I've heard many a rumor that uncle Sam wants to develop the Vulcan complex into a geothermal power plant. Let's hope that doesn't happen!

Vulcan Hot Springs used to have a couple different soaking options. Now there is primarily one. There are others, but because of the design of the main pool, difficulty awaits for the opportunist soaker. The main pool pool is huge. Without a doubt the largest in Idaho. Almost too large if you ask me, I'm worried that there is too much slow moving water. And yes, Red Spider Mites AKA Chiggers are active at this hot springs, but in low amounts. Just keep your clothing and towel away from the hot springs area.

Seasonal Notes
Accessible all year - dirt forest access road is not plowed during winter; access on horseback or snowshoe.

Camping Notes
There is plenty of Boise National Forest camping nearby along with some great primitive sites near the trailhead. Trailhead camping features a pit toilet, around 5 to 10 nice primitive sites, tons of trash, legions of ATVs and is extremely popular. Avoiding the crowds here means coming during the off season. I.E. not summer.

I don't know how, but our soaking party somehow managed to get Vulcan to ourselves on a busy Sunday afternoon. We hiked in as two groups were on their way out. We soaked, got out, ate a snack and headed back. On our way we passed two more groups on their way in. The second group was dragging along the fixins for some serious drinking. I had a sinking feeling when passing this last group that there would be a tremendous mess left behind.

The size of the main pool has been increased again, lowering the temperature to 103°. The soak was pretty good. I didn't say 'stellar' because I have a feeling that the main pool is too big, meaning the flow is too slow. I have recently been given additional hot springs measurement criteria that will shed some light on this. Next time I visit I will post the new results. Thank you Rick!

I came away with only 1 Red Spider Mite / Chigger bite. Out of my soaking companions, only one came away with bites, and only a couple at that. Once again, all 3 of us filled our extra bags with trash. This was quite the regular routine on this trip. Everywhere we went we were filling up bags with trash. On drive out I felt a quiet, sad feeling hit me as the realization that half my truck was full of trash set in.

Very nice indeed. Instead of 2 or 3 smaller soaking opportunities that often yielded mixed results we discovered that there is now 1, and it delivers! The large, log-dammed pool was a perfect 103°; excellent for toasty prolonged soaking. On our way in we passed a couple and their dogs (running wild off-leash) and a group of 3 on a 4-wheeler that just barley fit on the trail - all on their way back out. Everyone was cordial, and we found out that they were the ones camping near the trailhead. I was primarily stoked that we were able to enjoy Vulcan properly before the late afternoon storm picked up steam and chased us off.

The upper pool below the source was super toasty, while the middle pool was a bit cooler. Slight amount of goobers, tons of what I call a strain of government engineered super-mosquitoes (you've been warned... bring your bug juice or learn the hard way like I did) and no notice of trash made this somewhat worthwhile. The mosquitoes really did me in. Other than that though, AOK. The meadow just before the pull out was loaded with a huge grouping of Elk, a definite plus to the whole trip. On our way to the pools we past a lady with 8 kids! And, on our way out we past a couple scouting for a good HS for their family to soak in.

Just about every possible primitive site or place to park and camp at the trailhead was taken, only one, small space was left and no vehicles were in the TH parking area. On the 5th, there was actually about 3 open primitive sites and 4 vehicles in the TH parking.

There was a huge get-together of some sort going on just west of the trailhead. There was a small fleet of RVs, ORVs and at least 40 or so people, and you can bet they made good use of the hot springs. That's a little too many folks to share a soak with; so I left.

Word is that this weekend some off-duty BLM staffers are throwing a huge $50/head rager at the same location - exclusive invite only, and oh yes, kegs of beer. -That's just great, no additional comments from me because I'll just end up getting myself in trouble.
