Started at Talapus Lake trailhead and went up to Talapus, Olallie lakes and took the unofficial trail from the North end of the lake up to the Pratt Lake trail, then out and back to Island Lake. On return trip I followed the Pratt Lake trail further down to the official connection trail to Olallie lake.

Drive: road suitable to average 20 mph in a Prius until you catch up with two Subarus. Then you slow down to about 12 mph for the rest of the way up.  Same thing in the way down, except this time you're stuck behind a Hundai Elantra.  Seriously folks, drive as slow as you want, but pull over to let faster drivers pass. That's what I do when someone faster catches up with me. It's not a race! 

Trailhead: full, parked along the road about 0.1 miles down. Bathroom door jams a little, but opens and closes. Well stocked with TP at 9:15am

Trail: great condition, though 3 people placed poop bags along the trail in the first 0.1 miles. My pup pooped after 0.1 miles, and we returned to the trailhead with the poop bag before starting over. 

No obstacles on the trail to the north end of Olallie Lake. The unofficial trail from Olallie Lake to the Pratt Lake trail is easy to find but a bit overgrown lower down. From the Pratt Lake junction at the top of the ridge to Island Lake I cut out a few dozen Vine Maple and other low-hanging branches, but by far not all that are growing into the trail. No blow-downs on the way to Island Lake, though. 

Back country toilets: all signs are clearly visible and toilets are easy to find.

Talapus Lake: lid is broken (seat is fine). About 1 ft left til full. See Pic.

Olallie Lake: both toilets are full, about flush with the soil level. 

Island Lake: looks it got recently moved. Plenty of capacity left.

Note: DO NOT THROW TRASH OR POOP BAGS INTO THE BACKCOUNTRY TOILET! It turns regular trash into biohazard waste and will end up buried on the mountain. Still bad, but not as bad as dumping it in the toilet: leave it by the side of the trail. That way your mother (or some volunteer) can clean up after you. 

Hello.  Back on the trail with seven other senior hikers today, up to Ollalie. My last trip here was in November ‘24 and Ollalie was frozen and I needed microspikes on the trail. Not today, mid 80s and warm from the TH. 
We all got a parking spot at the TH today a Wednesday. Still lots of hikers up here. Privy is open (wasn’t in November) but no toilet paper. The road up is bumpy and I’m glad to have had my 4Runner. 
This trail is dusty now but generally pleasant.
Some swimmers at Talapus and some at Ollalie. But we went past the first spot at Ollalie to the second or third spot and our large group of eight had the space to ourselves for lunch.  

Left the TH at 10:20 and returned at 2:20. Traffic was bad and there was huge backups in both directions east of exit 45 and west around 436th a huge terrible accident. Yikes.  

I think I’ll go back when it’s less busy and snowy and visit Ollalie again…MJB

First time hiking this trail and first overnight with the kid. Got in to TH quite late and had to park way down ( ~0.3 mi) from TH. Late start at 1130am. extremely doubtful of getting any campsite but lucked out. Beautiful weather - a bit warm in the early part of the night and only cooled down after midnight. No (moving) water source after the bridge right before Talapus. 

Did not need to bring shades and hats as the hike is 99.9% shaded all the way

Loved this hike. We arrived at 8:30 on a Saturday and the lot was already full and cars were already parking along the road. When we left the line of cars parked along the side was really long. The gravel road to get here is bumpy with potholes; we didn’t struggle in our SUV but we did pass a car that was taking it very slow. We started at Talapus trailhead, hiked to Talapus Lake and continued on to Ollalie Lake and then back. It was so beautiful. I love how the moss covers the ground; it almost looks like the ground is glowing green. The path was wide which was nice when needing to pass other hikers. We were under forest cover the whole way, which was such a nice experience. Nice people and good dogs on the trail. Make sure to get your NW Forest Pass; there was someone giving tickets to cars without the pass.

My friends and I planned to hike Talapus and Olallie  lakes and ended up taking Pratt Lake as well. It was a beautiful day and the road going up to trail was easy. There's probably over 2 miles of gravel section going up but it is not something to be worried about because it is fairly easy and less potholes that even sedans can make it through.

Talapus was beautiful. It is less than 2 miles hike with lush trees and a wide trail. An easy hike that you will not even notice your arrival because the walk was enjoyable enough to worry about the destination. A few people camped out the night before mostly family with kids enjoying the water and hanging out with that floating log. I thought it was the cutest.

Olallie was also great, clear water with crawfish crawling in the rock under water where we were standing at. This is another 1.2 miles hike from Talapus. The water was so inviting and people bringing inflatables here and were just hanging out on the water. So bring some of that if swimming and relaxing is in your agenda.

Pratt lake was my favorite. It is another 3 miles to get there, I think. The last 1.8 miles is descending and you will walk through 3 section of boulders on this trail before you reach your destination. Lots of berries, different kinds that we enjoyed eating them. The water was the cleanest among them and I think this is by far the hardest to get into. 

Overall, it was an easy to moderate hike for me but long. My watch says we did over 12 miles total for round trip but it will probably depend on your pace. Enjoy!
