Overnight trip to Gilbert Peak from the Conrad Meadows Trailhead.
Getting to the trailhead
There is a bit to unpack here. First, contrary to the information on the hike finder map, the trailhead for all the referenced hikes is the Conrad Meadows Trailhead. Shortly after, the South Fork Tieton Road is blocked by a gate. It appears that it used to be possible to continue for another 2 miles and start the hikes there, as evidenced by an old information board along the way, but it's no longer the case.
Second, to get to the trailhead I'd strongly recommend to drive on the South Fork Tieton road from its beginning at Rimrock Lake to the trailhead. My GPS sent me through a shorter way that featured a subpar forest road and a few scared, free roaming cows.
Third, this trailhead is very popular among equestrians. We saw at least 5 horse trailers and many horses in the meadows (and two groups of horse riders on the trail).
Surprise Lake
Follow the South Fork Tieton Road until it is blocked. There you will find a sign which indicates the beginning of the trail. The trail goes through various meadows and light forests. Very scenic, but unfortunately not much shade. Eventually once crosses Conrad Creek, which runs quite deep with significant current, over a partially damaged bridge: It is tilted and some boards are loose, but it felt safe.
After following the river a bit longer, we took a left at the fork. That's about when the trail starts gaining about 1000 ft of elevation. Luckily, there was more shade in this part. Just before reaching Surprise Lake there were some small snow patches, nothing problematic. Surprise Lake is completely unfrozen and really nice - except for the mosquitos which were a pain.
Note that there are several creek crossings over logs all the way to the lake. None of the creeks have dangerous water flow, but the logs are often wet and unstable.
Warm Lake
After one passes Surprise Lake, snow takes over the trail. Every once in a while the trail is visible, but one really needs a map and or GPS. One passes various meadows and there is often water running under the snow. On a good note, we did not encounter any hazardous water flow, but that might change in the future depending on how rapidly the snow melts, so be careful.
Finding the trail that brings you close to the ridge ("Klickitat Divide") was hard, and we mostly went off-route to make our way. Eventually we found the trail in a large area where the snow was mostly melted out. We had to navigate little snow (and no steep snow), but this might be different depending on the route taken. Once one attains the area below the ridge, turn sharp to the left and walk on a pretty level area, almost entirely on snow. Every once in a while we saw the trail peak up under the snow. It's not until one reaches Warm Lake that the snow subsides. About a fifth of Warm Lake is unfrozen and the surrounding area is entirely unfrozen.
Gilbert Peak
From Warm Lake, go straight up the ridge. It's steepish snow, around 30 degrees, but currently the runout is as benign as it gets if you pick a route which goes straight up and bypasses some places where the snow melted and rocks are showing. Worst case, you will slide back down to where the snow levels. We used ice axes, but it was more like a good to have.
Once on the ridge - and this is different that what is in the description of the Gilbert Peak page - one can get up to Gilbert Peak without touching any snow. We walked maybe 30 feet over flat snow patches, and that could have been avoided. For the most part, there is a climbers trail and we have found it very straightforward to follow the ridge (once again, different than the experience described in the Gilbert Peak page). None of the route is exposed, so if you do find a spot with exposure, you are off-route.
The summit block has two short class 3 sections. One at the end of the climbers trail, and another to reach the peak. No significant exposure on the path we took until the last 10 ft or so to reach the summit. This stretch is a walk-up on small rocks, very easy, but exposed. There is a summit register at the top.
The views from the top were great and were dominated by Mount Rainier, Mount Adams, and Mount Saint Helens.

You're welcome. I do have the GPS track:
https://connect.garmin.com/modern/activity/7038902623
Let me add a few comments: I've turned my watch off on the way back at Surprise Lake since not much battery life was left. Both routes from Surprise Lake to Warm Lake are probably not the way to go as they did not follow the trail. The shorter trip was on the way down. It's completely off-trail and featured some snow and scrambling. The longer trip was the route up and if you compare with the trail you'll see that I took the turn way too late. I would recommend trying to find follow the snow-covered trail. If you encounter a stream with heavy flow and a large snow bridge (the South Fork Tieton River according to the map), you've missed the turn off and I would backtrack about 1000ft, that's where the trail should roughly be. Also - the snow bridge looked good this weekend but given the current heat it might become unstable soon.

I wish I had this!
This scramble was chosen from the Washington Scrambles book and I chose to do this without any GPS lol and that was a mistake on my behalf. Sort of. It was still righteous but I was not able to find Warm Lake.
I setout around 5 PM and chose to forgo Surprise Lake in leiu of the loop that I thought would bring me to the "Upper Surprise Camp" and eventually warm lake. That's the 1120 that bears Right and goes uphill.
I found a camp at night and decided to call it a night near the established fire ring. In the AM packed up and crossed the stream and proceeded to where I expected the trail to "Fade away" per the book. following the trail towards the NW and climbing to 3300' I eventually oriented to the Gilbert Peak but something didn't look right, however, it did look magnificent. Holy moly.
I continued and around 3400' I found the "Lake" that I believed to be warm lake, but it was not warm. It was indeed georgeous as far as alpine lakes go. Something akin to Broken Top mountain in Oregon for sure! I continued up the SW side per the book but eventually had to retreat as I don't think I could have safely gone further than 7400'. I was entirely on the wrong side. I never found warm lake. Later I learned I had encountered "Barren Lake." There's two gnar rock scrambles in loose rock that ascend a couple hundred feet and each and a large snowfield. I wouldn't attempt this route without technical gear, but I will return and go the surprise lake side.
After reading your notes and finding the GPS tracks you have, I actually believe the way you came down is the correct way to Warm Lake up what appears to be a dried out creek or whatever of rocks that goes up. I see where you went initially and that's where I had camped but I crossed the water near camp and proceeded to go left at the fork in the trail per NW as the book instructed. I was WAYYY off but the old map in the book makes it appear that I was in the correct place.
NEXT TIME! I gave a few hikers the 411 as I came down. I hope everyone else followed the GPS to Warm Lake and made it! Barren Lake is cool too and I'm about to research the beta on a summit of Gilbert from Barren Lake. Best of luck and happy trails!

seems I could have made it
Seems (maybe, your mileage may vary!) I could have made the scramble from where I was ~7200', but I would have had to cross the snow finger that sort of makes its way to the ridge where you start from Kickton Divide. It ends but I have some grainy photos where bug spray must've splattered but it looks like maybe you could almost reach the wall below the snow on the divide ridge and then climb up a bit. I think it's melted and broken now and I'm uncertain if one could safely cross from there and continue to scramble up to the SSW side. It would be splittersends for sure and I'd love to learn from anyone who has made it from Barren Lake! email my username @ gmail dot com!

UPDATE
So, I took the creek bed up that someone else told me was the way up. It was NOT the GPS tracks on All trails but seemed more direct. It was a bushwack and a scramble and prob saved a bunch of time but was a push. On the way out I took the GPS tracks from All trails I loaded and I still would have missed the intended "trail." I'll post a waypoint later but I don't know how anyone would know to start at this location or make it to their objective without someone showing them. It is very hidden. Summit is nice. Stayed at Warm Lake and did the summit per the Washington Scrambles Book. Looking at doing the Beckey route from Barren Lake some day in the future. NOT THE NEAR FUTURE THOUGH :) Time for another

Awesome TR, and helpful as I consider going in via Snowgrass Flat to ski soon. Did you find that the mosquitoes went away above treeline, or were they bad everywhere?

Thanks. The highest point where we encountered mosquitoes was on the lower portion of the Klickitat Divide. That is what is to the left of the large snowfield on the bottom of first picture until the rock cliffs. We camped where the picture was taken, at around 6700 feet, very shortly after attaining the ridge (on the GPS track you can it is a little bit South-East). Each of us got about 20 bites even though we spent most of the time in the tent.

Thanks! Sounds like I'll need bug spray for sure. Worse case I can just bail ;)

You're welcome. Bailing is never a bad option :-) but I should mention two things: First, we did not have bug spray with us. Second, my impression was that the mosquitoes were not bad at Warm Lake. If you plan to camp, consider doing it there.

Quick question, did you go Friday/Saturday or Saturday/Sunday...just curious because helps to gauge how much more snow melted from the heat Sat-Tues. :-)

Thanks! I was up to Warm Lake last Aug 4 (trip report on wta) and know where the trail goes without snow. But since several friends want me to take them up there July 8 (their only time to go - a gamble, I know!), if you have any pics of that semi-scree slope between 5800-6000 before you attained the ridge and turned sharply left and that area right when you attained the ridge or any other pics of the snow up there and don't mind sharing, my email is same as my wta profile name @gmail. Many thanks. No worries though!

I have one picture of the plateau area that I will send you per email. It's taken from our camping spot, just as the second picture I posted. The "semi-scree slope between 5800-6000" is completely snow-free in that elevation range. It's the 5400-5600 elevation range which had lots of snow which obscured the trail. I am not sure about the range in between as we were completely off trail. The area right before attaining the ridge can be seen in the second picture, it's almost entirely covered in snow. I give a short description in the first paragraph of the "Gilbert Peak" section.
