10 best things to do at Rattlesnake Ridge and Lake
1. Hike 2-miles up to Rattlesnake Ridge with an 1,175 foot elevation gain.
The 2-mile hike up to Rattlesnake Ridge can be accessed at the northern end of the lake, near the lawned recreation area and parking lot. This moderate hike is one of the best mountain trails within close proximity to Seattle, but gets super busy on weekends, especially during warmer months. Always check in advance if the trail to Rattlesnake Ridge is open. Can you see people at the top of the rock face?
The elevation gain to Rattlesnake Ridge is 1,175 feet above the lake, with superb views of Mt Si, Rattlesnake Lake and the Snoqualmie Valley. There's lots of drop-offs and cliff edges along the way, so extreme caution should be exercised near the unfenced sheer ledge, as lives have been lost here.
2. Enjoy wading or swimming in the crystal clear waters of Rattlesnake Lake.
The water temperature is usually around 62 to 68 degrees in summertime, but you can check the latest temperature here. There are no lifeguards, so you're swimming at your own risk. The beach on the eastern side of the lake is a gravel and sand mix.
3. Enjoy a BBQ or picnic on the shores of Rattlesnake Lake.
Rattlesnake Lake has a large lawned area, perfect for BBQs and picnics on lazy summer days, and a convenient restroom nearby. However, grills, picnic tables, and fresh water are not available at the lake, so bring everything with you. The whole area is owned and run by Seattle Public Utilities, who aim to keep it as pristine as possible.
4. Go kayaking or paddleboarding at Rattlesnake Lake.
In warmer months Rattlesnake Lake is popular for kayaking and paddleboarding, but there are no rentals at the lake. There's also a boat ramp, but only self propelled and electric boat motors are allowed. Always wear a lifejacket.
Take your kayak out on the shimmering waters of Rattlesnake Lake, with an 111-acre surface area to explore.
5. Go fishing for different species of trout.
Rattlesnake Lake has year-round fishing and is stocked with cutthroat trout and rainbow trout, but there are selective gear rules in effect for fisherman.
6. Learn about the ghost town of Moncton below Rattlesnake Lake.
It's fascinating to learn that the railroad township of Moncton used to sit at the site of Rattlesnake Lake. It had a population of around 200 people, and a school, saloon, restaurant and shops.
The town was flooded in the spring of 1915 when a new reservoir was built upstream behind a masonry dam, causing the water level of Rattlesnake Lake to rise by a foot each day. Within two months of the dam's construction, the town's homes and businesses were completely submerged.
7. Bike or walk along the southeastern shore of Rattlesnake Lake.
Take the beautiful 3/4 mile trail along the south-eastern edge of Rattlesnake Lake. The path starts at the beach area, and ends near the Cedar River Watershed Education Area. There's no loop path around the whole of Rattlesnake Lake, because the northern shore is closed to pedestrians.
The lakeside path has plenty of interpretive signs along the way, explaining the local history.

It's free to visit The Education Center at Rattlesnake Lake.
A fascinating model demonstrates how water travels from the Cascade Mountains to the Cedar River Watershed and down to 1.4 million residents in the Seattle area.
In 2000, the Cedar River Watershed Habitat Conservation Plan was implemented to protect 91,339 acres of the watershed and 83 fish and wildlife species. Over 200-miles of old logging roads are being returned to a natural state to prevent sediment from entering the water system. Stream habitats are also being restored.
Step outside the Education Center to the patio with a telescope, where you can see hikers up on Rattlesnake Ridge.
10. Check out the cool Rain Garden.
The first thing you notice when the approach the Education Center, is the steady beat of drums. It's easy to mistake this for a live musical performance, but the sound is actually dripping water cascading from the roof, to pound the tops of the drums in the Rain Drum Court.
