Sulphur Works is a 0.6 mile lightly trafficked out and back trail located near Mineral, California that features a great forest setting and is good for all skill levels. The trail is primarily used for walking and nature trips and is accessible year-round.
Lassen Volcanic National Park charges a fee to enter. Fees are $30 per vehicle or $25 per motorcycle. If you are entering on foot, horse, or bike the fee is $15 per person. During the winter (Dec 1 - Apr 15), entrance fees are $10. You can also purchase a park specific annual pass for $70. Access to the trailhead via Lassen peak Highway closes during the winter months and will reopen in the spring. A short, paved walk where plopping mudpots and smoking steam vents can be seen close to the roadside. Although paved, the sidewalk trail will be too steep for most wheelchair and stroller users without assistance (over 10% most of the way).
April 23, 2021Great little jaunt on snowshoes, without snow, a perfect little walk or drive for the kiddos. Check out my experience visiting Lassen in the winter for more detail: https://youtu.be/OTjJQvISgfM
March 13, 2021Really cool! Like a mini Yellowstone. Short trail and snow was packed down enough to walk on without snowshoes. Visited 2/27.
February 28, 2021Went when it was snowing . So I rented some snowshoes. Not crowded. Feb 2021
February 12, 2021stunning!
January 24, 2021Very cool but the
January 22, 2021We cover this trail in the first half of the video. https://www.youtube.com/watch?v=aDPfwqUGTJQ The trail is easy and perfect for first time snowshoeing! Easy access from the visitors center and some epic views!!
November 26, 2020In the snow when the road is closed, this is a 2 mile out and back trail from the visitor center. Fun little stop, takes about an hour.
November 3, 2020November 1, 2020Not a trail. Worth 10min
October 17, 2020Short walk along the road to see some bubbling mud pots. Worth the stop.
September 14, 2020A few feet from parking lot. Boiling mud pit is worth the quick stop and photo op. Good if you cant make it out to Bumpass Hell trail!
August 26, 2020August 2, 2020This isn’t actually a hike, just a short walk from the parking lot that follows the road. The attractions are viewed from the sidewalk and are the closest you’ll get to a boiling pit unless you go off boardwalk on the bumpass hell trail. I would say it’s still worth a quick stop since it’s such a unique set of landmarks!
July 4, 2020It’s a super short walk (distance from the parking lot to the entrance of a grocery store). It’s a quick stop on your way to other attractions. It smells really bad.
November 18, 2019I came to this Sulphur Works again ( 11/17/2019) since I visited the park. No need to hike, just park your car in the parking lot, walk up for few hundred feet and you are there. I love to see hot mud still active. Smoke and smell up to the air at one, I don’t know how hot or warm of the liquid in the pool, I was here last year in summer and the smell of the pool so bad, I think fall season the pool smell must better. I will stop here again when I come back to this park.
September 3, 2019Not really a hike... just right off the road. Still a cool sight to see
September 2, 2019I hiked the full mile up to the lake, which was quite uphill. If you're looking to conserve energy/time don't hike all that way up (nothing special about the lake up there), but only up to the point where you see a little boiling pond to the right, then back down to the parking lot and across the bridge to the boiling mudpot which was the most impressive active feature I got to see up close. Bumpass hell active features are quite far (I presume for safety), so I wouldn't skip coming here to get a good close look at that boiling mudpot.
September 2, 2019Not a trail...just a stop on the road...a worthy one. Also trailhead for Ridge Lakes Trail ...but I’m out of daylight.
July 15, 2019This gets a 4... as a road stop to see close volcanic features. No real trail! See below for trail definition. Photo op, look at mud pits for 15 min, then go on to the real hiking.
July 14, 2019Sulfur Works are the volcanic features along Highway 89 (Lassen Peak Highway) and not the trail profiled and shown on the map. What is shown is actually the first 0.6 mile of the Ridge Trail which is a moderatly difficult trail. If a real hike is what you are looking for, I recommend you check that trail out and hike all the way up to Ridge Lakes.
July 8, 2019I have no idea what people like about this park, and what got it a 5 star rating overall from almost 2k reviews. We wasted the 4th of July long weekend by going there. The park is very far from any accommodation, and only after you get there they tell you that their website is telling a half truth when it says the trails are open.. they are technically open but you have to have snow gear to be able to trek on 4-20 feet deep snow.. melting on sloping trails!! The Sulphur Works is fine but just a quick stop is all what you can do there. The Cinder Cone is in another part of the park that is another hour drive (and back), and the Devil's Kitchen/Boiling Spring Lake/Terminal Geyser trails are in yet a third part of the park that you can only reach by driving on a dirt road after 2 hours of driving around the park in narrow roads with no cell coverage (limited mobile phone GPS). All in all it was a weekend of driving, from San Jose up to the closest place where we could find accommodation (redding), the. In and around the park. Totally NOT worth it.
October 26, 2018Facinating.
October 13, 2018Awesome mud pots
September 9, 2018No hiking, just walking from your car. A wheelchair would have noooo problem. The boiling mud pit is impressive to say the least and its only about 2 feet from the sidewalk! I saw an elderly woman at the fence near it get blasted with a burst of sulphuric steam and she had to jump back into the road to avoid getting scorched. Her glasses were completely fogged and her hair was damp. Must've smelled great. Be careful.
June 19, 2018No actual trail, a short walk from the parking lot gets you up close with the mudpots. Educational experience for the kids and adults too. Due to Bumpass Hell being closed for repairs this short walk has a great alternative to seeing the mudpots in the area. Easy enough for kids and even witnessed a person in a wheelchair doing the walkway. The sulfur smell isn’t as bad as some say and didn’t bother me, but bothered my husband. Great short walk and would definitely return again in the future
May 9, 2018Very short hike sulfur beds interesting
May 1, 2018As others have mentioned, this is a walk near the parking area with some nice informative exhibits and an up close and personal taste [and smell] of volcanic mud pots and ecosystem impacts. Worth a stop.
April 8, 2018Walked up to the sulfur pools in the snow, went sledding
September 15, 2017June 13, 2017furthest point allowed to drive to as of 6/11/17... you can walk the rest of the road bed but undrivable until trees and rocks are removed... i walked about 2 miles up to near Bumpass Hell... pretty sure any offroad hiking must use snowshoes as there is still many feet of snow pack
