Great hike. Gorgeous views. My grandkids loved playing in the lake. We will definitely do it again.

Not too much variety in scenery...good workout, and well maintained trail but no views until the top.

We arrived at the trailhead at 8:40am today. We find a parking spot in the parking lot. The trail was not very busy when we hike. The view at the top was stunning! It’s a relatively easy trail in my opinion, not so much as moderate. When we hike down, the amount of people gets larger and we feel fortunate to start early.

Started the trail at 830 am to avoid a lot of the crowd but it was still pretty packed at that time of day (probably because it’s a weekend). Moderate hike to Rattlesnake ledge and the view was definitely worth it! We continued on to Eastridge (I think that’s what it was called) which is 2.4 miles up from Rattlesnake ledge. There is a great view if Mt Si from the top with a bench to enjoy the view.

I went a couple months ago on a Monday afternoon and it was still crazy busy! The view is beautiful and the hike up was very scenic.

I went up the new trail and down the old trail. I packed light and alternated between jogging and “striding out“ on the steep sections. It took me 1 hour 40 minutes to the top. Here’s what I learned:

Top 10 tips hikers need to know for Mailbox Peak:

1. Parking is a nightmare. Instead of battling for a parking space, park 10 mins down the road at Twin Falls Middle School. Bring $2.75 (each way, so $5.50 total) or your Orca card to pay the fare. There is a sandwich board where to stand for the shuttle, which comes ever 10-15 minutes. You can’t miss it, and it beats the hassle of parking.

Note: there are pit toilets at the parking lot once you get dropped off from the shuttle and you walk uphill. Please close the lid of the toilet, guys.

2. Once dropped off by the shuttle, walk up the paved hill until you get to a gate across a gravel road (on your left). Just look for the big gate/bar across the road... That is the start of the trail. Follow this gravel road uphill until you get to the trailhead. (You’ll see a sign) Head left, and walk uphill until you get to the top!

Note: these directions are for the “new trail.“ If you want the “old trail,” keep going up this gravel road until you come to another sign on your left that indicates Mailbox Peak. Head left and up!

3. Most important tip: bring water. Seriously bring LOTS of water. There are no creeks, streams, or lakes. I jogged/fast-walked the entire thing, so I wasn’t hiking long, so I thought I could get away with just 2 liters. I STILL ran out of water 1/2 way down. Sure I survived, but I felt pretty gross driving back. Recommendation: bring a gallon of water. Yes it’s an obscene amount, but you will thank me. You will have a difficult time choking down that much water, so sprinkle some Kool-Aid powder or power aid mixture to give you an incentive to drink it.

4. Mailbox at the top: Bring a sticker for the mailbox. Don’t be that guy who puts food in the mailbox. That’s why there are flies everywhere—from the person that day who put a box of raisins to cook in the mailbox.

5. Old trail? Or new trail? Unless you are in marathon running shape, do NOT take the old trail up OR down. The old trail is very technical with lots of roots. Seriously you can’t walk 12 inches without getting your foot caught on a root, which is exhausting (or challenging!).

Recommendation: take the “new trail.” The volunteers who put the new trail together did an absolutely INCREDIBLE job with it. It’s smooth, rolling, and easy to pass people (double wide!). You will thank me! But if you choose the old trail, unless you run Spartan races continuously, you will tell yourself “We should’ve listened to that review on AllTrails.”)

6. Sunscreen, yes or no? Virtually the entire trail is shaded, which is perfect for summer hiking. Up until the last part, when you hop out onto the exposed rock, only then do you start to bake. Recommendation: right before you come out of the trees, slather up. Seriously the sun is 27,000,000°F and your dreams of your “light sunburn turning into a tan” is only an illusion.

7. Beer at the top? Yes, getting to the summit is exhilarating, but celebrating by drinking a diuretic is the last thing you want to do to your body. Remember, when you’re at the top you are only 50% done with the hike. 90% of mountaineering accidents happen on the way DOWN, when fatigue is setting in and gravity is pulling you down. You need to be on your A-game going downhill, not buzzed. Save the beer for when you get home, and even then re-hydrate. If you insist on sipping a beer at the top, just know there are a lot of people laughing at your pretentious hipster self.

8. 10 Essentials: bring them. From a first aid kit (including mole skin) to a flashlight. The only thing: bug repellent isn’t really necessary. There is no standing water nearby, and odds are when you are sitting up on the summit, away from the mailbox, there will be a slight breeze to keep the bugs away.

Tip: trekking poles will save your knees if you are hiking. Running? They will get in the way.

9. Save cell phone battery life: Using the All Trails app to record your hike, right after you press “record“ (at the start of your hike of course) switch your phone into airplane mode. This will save your battery and it will still be tracking your GPS signal. Tested on a very well-used battery on an iPhone 6s, and still had 80% battery life after the entire hike.

10. Dogs: there are quite a few. I love seeing them. But please if you’re a dog owner, bring bags for the dog poo and pack it out. Don’t kick the poop off the trail into the bushes... I know it’s “natural“ and there are a lot of animals that poop in the woods, but we can still smell it fermenting—especially after 100 dogs/day go on the trail. Plus dog poop has a very distinct odor that tends to ruin the moment. And of course, lots of water for doggo!

This is a fantastic hike that every WA hiker must go on.

It was a beautiful hike. But for dog owners beware of the rocks that could be too hot for your dogs paws.

Nice fairly easy hike. A few little short inclines, but nothing too tough. Hiked it with or 2 year old in a backpack and she even did a couple of short stretches. The hike itself is gorgeous with amazing rock features, but the views at the end are a little lackluster. We started early, which turned out to be a good idea as it got pretty crowded and pretty warm on our way down. Overall a nice short morning hike. Also, everyone was very friendly and all the dogs were well behaved.

Easy hike, short with many families. I took Nook Trail off Bus Trail. Nook Trail is more difficult and has a climb. Not for children or beginners. There’s not much to see at the top but it’s a good training trail for my hike later this Summer in Lolo Lolo National Forest in Montana.

Nice shady hike on a hot day. Great views at summit.

Pretty gradual with switch backs the whole way. The whole trail is shaded. took me about 3.5 hours I believe.

such a great experience!! This place was my first mountain hike ever. Seeing those kinds of beautiful view made me so much interested doing mountain hiking. It inspired me alot and that I won’t never forget this place. After I went here last 2 months ago, I started to do more hiking trails and discover myself that i love hiking.

Gets steep at the top but the overall hike itself is easy and doable. For the hike, the views at the top are breathtaking. Recommend hike for all Seattlelites and visitors to the area

Hard, but worth it. Amazing views

The Mount Si trail is a decent trail to hike. There are minimal scenic views throughout the trail because it’s mainly wooded. When you get to the top of the trail you finally get to see mountain and valley views. If you want the best seat in the house, go around to the back side of haystack and make the climb up. It’s a little challenging and should be done with caution, But if you make it to the top of haystack it makes the boring first hour and a half of the hike worth it.

Parking is very limited unless you arrive there very early like 6:30 am and the trail is not difficult

this was my very first hike. I made some mistakes. if you are going with more experienced hikers distribute the weight of bags thoughtfully. I had a backpack and it was way too heavy it made the experience way more hard than it needed to be. Learned a lesson! Also might wanna go with someone patient and helpful if you are a beginner. I had to stop a lot. Also remember to stretch! The view tho. so beautiful

Love that it’s consistently steep and mostly shaded. The opening at top to panoramic views is an epic payoff.

One of the best trails in the area, beautiful 360 degree view. Last starch is pretty hard. It is more than 13 miles loop but not sure why it says 8.2 miles.

Hiked this trail a couple days ago, on Friday afternoon. New trail to me, and a bit out of shape, but felt like this hike was a good workout with a reward at the top!
Be prepared for a steady incline that gets your heart rate up, and know that this is a popular trail...lots of people and traffic... do your best to follow hiker etiquette!
It's a long way to the top, but you'll definitely be rewarded for your hard work when you see the views! Love that the lake is there, too...great spot for a family day with multiple things to do and see. Will be visiting again, for sure!

Use the directions through this app to get there because I’ve had friends directed to a different place when they looked up the location. Parking is free! The lake at the bottom of the trail is so beautiful. It looks even better once you’ve reached the top. This hike is as busy as everyone says it is. Sadly, people leave their trash around, like pistachio shells, gum, etc.

Not a bad hike but a lot of people at the top. I’d recommend going before 8am if you want to avoid the crowds.

It is good challenging trail.

The trail itself is kind of boring. It's a nice forest and all, but it's a bit monotonous, not to mention, very busy and you may have to park quite a ways away. there's also no views until literally the very, very end of the trail.. not even a glimpse. the view at the end though IS stunning, but gd it people, don't play music on trails and stay to the right when you can.

It was beautiful at the top but get there before 7. Very busy and most people there have zero trail etiquette

This was my second hike. Hard, but rewarding when you got to the top.

enjoyed the hike, the view from the ledge is beautiful, although crowded. we chose to hike the extra half mile to the east ledge which we had to our selves for a peaceful snack break.

Hike #3 ✓

The lake view from the ledge is very rewarding.
