A very unique hike through an obsidian lava flow beneath Paulina Peak in Newberry Crater, Oregon. Throughout the flow, there are interpretive signs telling the history of the area, from the eruption 1,300 years ago, to the colonization of plants and animals, to the use of the glass by native tribes and its trade throughout the west. You'll have great views up to the top of Paulina Peak above you and across Paulina Lake.

This is fabulously unique. Definitely not your typical hike through the woods. It is short and relatively easy, but beyond the first viewpoint there are a couple of areas where you have to negotiate some big pieces of sharp obsidian almost the size of a boulder.

I would recommend this trail to anyone wanting to see large pieces of obsidian and to look at the awesome power of lava flows. Not much shade and can get pretty bright and hot during the summer. Highly recommend.

Super interesting! I can see why dogs aren't allowed. This trail would chew up their paws.

Great big beautiful Obsidian rocks everywhere. Illegal to remove from the trail with a 500.00 fine. Trail is easy but there are stairs at the beginning of the trail. Not good for disabilities. Dogs must wear shoes as the rocks are prolific and jutt out of the ground very sharp, and could easily injure your pup. I

easy hike to the top and back. So much obsidian!!!! Anybody could do this hike.,Great views of flow, the trees, and Paulina Lake. Not supposed to take any obsidian from the site, but as long as its a small piece, I don't see the harm.

Really unique spot. Short stair walk followed by a kind free flow scramble over obsidian. Good for kids but probably not pets (sharp rocks.)

A beautiful northwest day! This trail and the interpretive information was more interesting than I was expecting--a pleasant surprise. Length of the trail was just right for the scenery. Definitely leave your dogs home due to the sharp obsidian all along the trail.

Do not bring your dog. Saw a couple dogs limping away after the hike. The path is literally broken glass.

It's a very unique experience. The trail begins with a some pavement, then stairs, and then rocks and dirt. It's short for sure and offers neat signage and picture opportunities in several spots.

One of the things I loved was seeing the various texture together within the rocks layers of obsidian with lava and pumice. The view from the top was beautiful.

Great interpretive trail with super interesting facts. There was a ranger at the top of the climb who gave us more interesting history of the area. I like these types of trails because they’re different and interesting. Neat view of the “pond” at the bottom of the slope and also mount bachelor and South Sister

A fun, short, uphill hike. The kids loved seeing all of the "shiny" rocks. There is a swampy area nearby that was pretty and it is really nice to read the information that is available to read along thr path. The only thing to watch out for is that there are many sharp rocks to watch out for, so wear shoes.

This was one of my favorite hikes in the Newberry National Volcanic Monument. The hike begins with a series of steps, before you wander along the obsidian rocks. It was a beautiful hike with very interesting views with smooth and rough obsidian rock surrounding you. What made this hike my favorite was the contrast between the obsidian rock and the forests surrounding it. made for a beautiful contrast in view.

Majestic and awe inspiring, if you're someone who is impressed by mother nature and her amazing feats that is. The drive up the mountain is beautiful, with much more than just the flow to see. Please be aware your car will require a pass, purchased at the entry gate, and that it is absolutely illegal to remove anything. Allow others to enjoy the Obsidian Flow as you did, and resist the urge to grab a souvenir...in other words, don't be that guy. Dogs are not advised on the flow without footwear, the obsidean will cut their pads, and please also wear proper shoes. Do not wear sandals, heels, or anything open toe as the trail is undeveloped. I recommend bringing a water bottle as well. This is an easy hike once you make it up the stairs. My 3 year old can smash it. Just watch where you place your feet and be extra careful on the still present snow patches. Also know, there are no safety rails once you reach the trail head and the area is not handicap accessible.
