Why Backpack the Alice-Toxaway Loop in Idaho’s Sawtooths

The Sawtooth Mountains in central Idaho are a backpacker’s paradise with rugged, scenic views, and it’s far less crowded than other popular Northwest ranges. With jagged peaks, crystal-clear alpine lakes, and miles of backcountry trails, the Sawtooths are one of the best places in Idaho for an overnight backpacking trip. On our second visit to the area, we opted for the classic Alice-Toxaway Loop, hiking it counterclockwise and spending one night at Toxaway Lake. If I were planning it again, I’d stretch it into a two-night trip with a night at either Twin Lakes or Alice Lake as well.

While the standard Alice-Toxaway Loop is about 19 miles, it’s easy to add extra lakes or summits. We decided to extend our route by climbing an additional pass that isn’t part of the traditional loop—and the views were absolutely worth it. Our version included a detour to Edith Lake and a quick, easy summit of Sand Mountain before dropping down to Toxaway Lake for the night. The next morning, we continued from Toxaway to Alice Lake and then back to the Tin Cup Trailhead, finishing with 24.5 miles and 4,758 feet of elevation gain.

    2-Day Alice-Toxaway Loop Itinerary

    Day 1: Tin Cup -> Edith Lake -> Sand Mountain -> Toxaway Lake
    Distance: 11.5 miles (18.5 km) | Elevation Gain: 2,930 feet (893 m)

    We started at the Tin Cup hiker trailhead at Pettit Lake and shortly after starting we took a right fork to head up and over the ridge. The first few miles were in the forest and nice and shady. We hit our only creek crossing for the day around mile three. It was running high, up to knee deep, so we switched into sandals to cross. After that it was an easy and mostly flat trail to Farley Lake, where we ate lunch. From Farley we forked right and began gaining elevation up to Edith Lake, which was beautiful but just a stop along the way.

    Above Edith Lake, heading up to Sand Mountain

    Past Edith we entered the high alpine, filled with rocky peaks and small tarns, along with a little bit of patchy snow (nothing that you could not cross in trail runners). We continued up to the pass below Sand Mountain, dropped our packs in the saddle, and hiked up to summit Sand, which was a very short detour and well worth it for the views. From there we hiked up to another rideline above Toxaway, and then descended to the lake to find a campsite.

    Toxaway Lake is huge and has many campsites surrounding the lake. We opted for one a little higher up that we could have both lake and mountain views. Our spot also felt secluded even though there were others camping nearby. We went down to the lakeshore for dinner and to filter water, then headed back up to our campsite for the night. The mosquitos were not awful until dusk, then they really started to come out. We were already in our tent by then so they didn’t really bother us.

    Day 2: Toxaway Lake -> Twin Lakes -> Alice Lake -> Pettit Lake
    Distance: 10.6 miles (17 km) | Elevation Gain: 1,127 feet (343 m)

    We woke up just before sunrise to watch the light come over the peaks. The mosquitos started coming out shortly after sunrise, so we set up our Thermacell Backpacker on a fuel canister to create a bug free zone while we made breakfast and packed up camp. Once packed up, we headed back down to the water to fill up our bladders for the hike over the pass to Alice Lake.

    After ascending above Alice, we reached a couple beautiful, high alpine lakes and tarns, along with an exposed trail up to the pass. Coming around the corner, there was a large patch of snow at the pass proper, but it was easy to walk on. I was blown away by the view of Twin Lakes below, and was happy that we decided to hike counterclockwise to get this amazing view at the top.

    From there we descended to Twin Lakes and then to Alice, with amazing views along the exposed trail. We stopped for lunch at Alice Lake, and then continued on down. The trail between Alice and Pettit Lake has at least four creek crossings that can’t be avoided, so be ready to put your sandals/water shoes on. We ended up leaving our Teva sandals on for several miles, knowing that we had more crossings ahead. It saved time instead of having to put our trail runners on and take them off again. Other than the creek crossings, the trail was in good shape until a short section of down trees from a large avalanche that must have come through over the winter. There were cairns to follow across a boulder field to get you back on track.

    The rest of the hike out was very gradual, and a little cooler once we got into the trees. Then you hike along Pettit Lake until you get back to the Tin Cup Trailhead where you started.

    Route Variations & Add-Ons

    One of the best things about the Alice-Toxaway Loop is how customizable it is. The standard loop is already packed with incredible views, but you can easily add side trips, extra lakes, or even a summit if you want to stretch the adventure.

    Edith Lake Spur (Highly Recommended)

    As detail in the itinerary We added a side trip to Edith Lake, which sits in a quiet basin away from the main loop. The climb is steady but short, and the extra miles are absolutely worth it for the turquoise water and peaceful shoreline. This detour adds roughly 2–3 miles depending on how far you explore.

    Sand Mountain Summit

    If you want an easy, non-technical summit with huge panoramic views, Sand Mountain is a great option. From the ridge near Edith Lake, it’s a short and mellow climb to the top. This adds less than a mile and gives you one of the best perspectives of the Sawtooths.

    Twin Lakes Overlook

    Whether or not you camp here, take a quick detour to the Twin Lakes overlook. If you’re hiking counterclockwise, the elevated viewpoint hits you with one of the most dramatic reveals of the entire loop. It’s a short, worthwhile spur off the main trail.

    Snowyside Peak (Advanced)

    For experienced hikers comfortable with off-trail travel and class 2/3 scrambling, Snowyside Peak is a big, rewarding add-on. You’ll get sweeping 360º views across the Sawtooth Wilderness. Only attempt this in good weather and low snow conditions.

    Alice Lake Out-and-Back

    If you want a shorter option, Alice Lake makes a perfect out-and-back day hike or overnight. You’ll still get alpine lakes, big granite walls, and postcard-perfect views without committing to the full loop.

    Permits & Leave No Trace

    The Alice-Toxaway Loop sits inside the Sawtooth Wilderness, which has a few important rules.

    Permits

    You do not need a reservation permit, but you do need to complete a free self-issued wilderness permit. You’ll find the permit box about one mile from the Tin Cup Trailhead at the wilderness boundary on your hike in. Fill it out, keep the top copy with you, and drop the rest in the box.

    Leave No Trace Ethics

    • Camping: Camp on durable surfaces atleast 100 feet from lakes and streams. Stick to established sites where possible.
    • Campfires: Campfires are prohibited in certain high-elevation and sensitive areas. Always check current fire restrictions at the local ranger district before you leave.
    • Food storage: Use a bear canister, bear bag, or hang your food at least 200 feet from camp and 10 feet off the ground.
    • Stay on trail: Cutting switchbacks causes vegetation damage and erosion.
    • Pack out everything: All trash, food scraps, and toilet paper. If you packed it in, pack it out.
    • Waste disposal: Dispose of human waste properly by digging cat holes at least 200 feet from water, trails, and camp.
    • Don't feed wildlife: Human food is harmful to wildlife and creates problem animals.
    • Leave rocks and plants: Don't build cairns, pick flowers, or move large rocks.
    • Be considerate of others: Respect people's space and wild experience by keeping noise to a minimum.

    Backpacking Gear List

    We usually both carry the Hyperlite Mountain Gear Southwest 55L, but I decided to test out my new Unbound 40L on this trip. After a full day on trail, I realized I still prefer the Southwest for overall comfort, and I’d recommend it as the best ultralight pack for multi-night backpacking. It’s also great for a quick overnight, and Garrett was perfectly happy with his.

    FAQ: Alice-Toxaway Loop Backpacking Guide

    How difficult is the Alice-Toxaway Loop?

    The standard loop is rated moderate to challenging due to elevation gain, creek crossings, and some exposed sections near the passes. If you’re comfortable with 10–13 mile days and carrying an overnight pack, this loop is totally doable.

    Do you need a permit to backpack the Alice-Toxaway Loop?

    You do not need a reservation permit. Permits are self-issued at the wilderness boundary ~mile into the trail. They’re free and help track visitor use.

    When is the best time of year to hike the loop?

    Late July through mid-September offers the most reliable snow-free conditions. Early summer can still have snow patches near the passes. Mosquitos peak in July.

    Can you do the Alice-Toxaway Loop in one day?

    Yes. Many trail runners and strong hikers complete it in a long day, but the best scenery is worth an overnight.

    Is the loop better clockwise or counterclockwise?

    Counterclockwise gives you the most dramatic reveal of Twin Lakes from above.

    Are dogs allowed?

    Dogs must be on leash while on trails from July 1 through Labor Day. Keep them under control, as loose dogs can harass wildlife, livestock, and other visitors.

    Are there designated campsites?

    There are no official designated sites, but there are many established backcountry spots around Toxaway, Twin Lakes, and Alice.

    Is there cell service on the trail?

    Cell service is very limited to nonexistent. Download offline maps before you go (Gaia GPS recommended) and carry a satellite messaging device such as a Garmin InReach Mini 3.

    Final Thoughts

    Backpacking in the Idaho Sawtooths is such an amazing experience. Every time we go, it reminds me of the Enchantments in Washington but with way less people. If this loop seems like too much for you or your group, there are a lot of other shorter options that make great one night trips. If you are planning a trip to Idaho, I highly recommend adding the Sawtooths to your itinerary, even just as a day hike.
