Pratt Lake Trail

Trip

Day Hike - Rainbow & Island Lakes

Sneak in one more trip to visit beautiful alpine lakes before the snow sets in for the season -- on this 11-mile hike, we’ll see Talapus, Olallie, Island, and Rainbow Lakes. We’ll aim to do this at a moderate, 1.5-2mph pace so that we’re able to take photos and enjoy conversation along the way.

We’ll consolidate carpools at the Preston P&R (Exit 22 off I-90). We’ll aim to be on the trail by 9am, so we’ll meet at the P&R at 8:15am and leave shortly thereafter. If you need to meet us at the trailhead, please be there by 8:45am and let me know in advance so we’re not waiting for you at the P&R.

Trailhead directions: We’ll start this hike from the Talapus Lake Trailhead. Take I-90 to Exit 45 and go left onto USFS 9030. After 0.9 miles, turn right to stay on USFS 9030. After 2.3 miles, you’ll arrive at the trailhead. NW Forest Pass required.

Visit four (!) alpine lakes in one hike: Talapus, Olallie, Island, and Rainbow Lakes. We’ll start from the Talapus Lake Trailhead and hike an easy 1.7 miles in to Talapus Lake. From there, we’ll hike toward Olallie Lake and split off at the junction for the Pratt Lake Trail (2.4 miles in). We’ll hike up and around Olallie Lake, peeking down on it from above, and then splitting away from the Pratt Lake Trail (going left on trail 1009, 4.6 miles in). We’ll reach our highest elevation (4400’) after 5.7 miles, and shortly after, we’ll reach Island and Rainbow Lakes. We’ll break for lunch there, stopping to admire the view, and then head back down in the afternoon.

We’ll take this at a moderate pace (1.5-2mph) which means we’ll be out for most of the day -- if folks are interested, there are plenty of options for dinner in Issaquah. The trail will be muddy and there may be rain, so make sure you’re ready for a wet day. Luckily, lakes are still beautiful when it’s misty!

Required equipment: the Ten Essentials (always). We’re well into fall now, so if you haven’t done this already, please take time to look through your kit and make sure you’re prepared for the weather change. Having rain gear and insulation (extra layers) is important at this time of year. You may also wish to bring traction (microspikes, etc.) in case we encounter a bit of snow at the higher elevations.
