The trail is definitely difficult. Beautiful views. If you are planing on camping at Thousand Island Lakes, pack light!

Solid full day hike! We arrived at the trail head at 7 am and there were a tons of cars already since they probably belong to backpackers. We took the River Trail to Thousand Islands Lake and the High Trail on the way back to make a loop and maximize the views! We hiked this trail last week and it was in the mid 80s with very dry air and not a single cloud in the sky, which makes the hike even more exhausting from the heat. I would recommend taking the High Trail in the morning instead since it has a lot of exposure and it does add an extra 200 feet of going up and down compared to the steady incline of the River Trail.

Phone died so we recorded only the way up. Since the route has some ups and downs (especially the first couple of miles), to find the true elevation gain one needs to add a few hundred feet. In all, 25.4 miles and a bit more than 5,000' of elevation gain. Amazing views of Ritter, Banner, Lyell, and 1000 island lake from the top.

We went up the river trail to thousand island from Agnew and didn’t fully appreciate how much uphill there was on the way back via Garnet and Shadow lakes. Hands down most scenic hike we’ve ever done, but it was uphill both ways! The recording says 18 miles but I missed out a section and my other half’s recording said 24 miles so most likely somewhere in between as there was some extra exploring here and there. We took our pooch and he loved it.

Great trail, everywhere. Some heavy use near Agnew Meadows, but most well-maintained. The un-maintained Mary Muir trail from Garnet Lake to Thousand Islands Lake was easy to find, and follow. Typical mosquito activity, so bring your repellent.

Thousand island is magical! The first 5 miles are rather tedious and filled with bugs. Did our own loop with pct on way to thousand island and jmt back. JMT was better! Forgot to turn off the recording at the car at Mile 19

Much less crowded than the lakes basin. If you drive down to Red’s Meadow before 7 AM or after 7 PM you avoid the $10 entry fee. I chose to do a through hike with the final destination being Silver Lake by June Lake. 6/29/20

This was a solid day hike we completed on 10/11/19. The views and scenery on this hike are wonderful! Lots of vibrant colors and stunning views. The trail had at least 5 water crossings which was water flowing down the hill and over and through the trail. These crossing were often partially frozen and created beautiful icicles. What I loved about this hike were the leaves changing to fall colors, colorful and plentiful flowers, cool rock formations, great views and the lakes are a jewel!

Ok! So I did this trail (Oct 4 & hiked back out Oct 6) last weekend, here are some pointers: this route is probably the easiest way to reach 1000 Islands, during this time of year it is COVERED in butterflies, the hike in/out is STUNNING with sweeping views of the mountain ranges, there is no shuttle from Mammoth Ski Resort this time of year so you just park at the Agnews Meadows trailhead (after a $10 car fee). Just continue to follow the trail markers for the PCT and 1000 Island Lake. Super dog friendly hike, didn’t have any issues. TOTALLY RECOMMEND! P/s VERY cold at night during this time of year (hit 19 degrees the first night). And yes, permit needed. Got mine from the Ranger Station in Mammoth Welcome Center.

Went up to Thousand Island two consecutive days! The first day I took the much harder Shadow, Garnet and Thousand Island loop but I heard from hikers how much easier the PCT route was so I decided I couldn't leave Agnew Meadows without checking out this route too! I thought this way would be harder cause it starts ascending but once you get past the switchbacks you go up gradually as it starts to level off and you get a great view of the Minarets and Shadow lake on the other side. Since the trail starts at high elevation there isn't anymore crazy gains in elevation making this a long but enjoyable trail. I took it out and back and it was way easier than the loop. But both ways are beautiful and full of memories.

We took the River Trail from Agnews Meadow up to Thousand Island Lake, then back along the High Trail and dropped back into the back side of the parking lot by the pack station. Beautiful views. Was chilly at times (even a few snow flakes!), but we were prepared. Definitely not for the faint of heart, but well worth the effort!

All clear and well marked trail with few small and easy creek crossing. Was there 8/15 and it’s getting chilly at the top when the wind blows. Do the loop past Ruby and garnet lakes if you can. Ruby was my favorite this time of the year.

We hiked up there from PCT High Trail) and exited at River Trail (Shadow Lake) last July 18 to 21. Thousand Island Lake is a paradise, the weather was perfect, it wasn’t windy, or cold as we expected! There are still snow patches but it was dry and no mosquitoes as we were told. The trail going to Garnet Lake was sketchy since the trail was covered with snow ,We almost lost our track, good thing we had navigation device. Garnet Lake was swampy and swarmed with mosquitoes! The trail uphill going to Shadow Lake was a little scary for me esp coz we had kids. it was covered with snow going uphill. It was doable tho but take extra caution. Our nine year old, 12 yo and 16 yo girls did fine and was actually sledding parts of the snowy hill. This is one of our most favorite backpacking trip as a family. - Marichelle Bustamante

Great trek. We did the PCT High Trail out, and the River Trail back. The High Trail was the more impressive of the two. Hardly any snow left on the trail by this time. Mosquitos were a bit of a nuisance
