The trailhead for Greider Lakes Trail has a dedicated parking area. You'll need to stop at an information kiosk to register before starting your hike. Arriving early is often recommended, especially on weekends, as parking can fill up.
Yes, you will need a valid recreation pass for parking at the trailhead. The trail is located within the Morning Star Natural Resources Conservation Area, which is part of the Sultan Basin Watershed. While there isn't a separate entrance fee for the conservation area itself, standard Washington State Parks or Forest Service passes are typically required for parking.
The trail is generally dog-friendly, but dogs must be kept on a leash at all times. Remember to pack out all pet waste to help preserve the natural environment, especially since the area is part of a public water supply watershed.
The best time to hike is typically from late spring through early autumn. In spring, you can enjoy vibrant wildflowers, while autumn brings brilliant red berry bushes. Summer offers the most reliable weather. Winter hiking is possible but can involve snow, ice, and slick conditions, making it significantly more challenging.
The trail offers varied terrain. The initial two miles are relatively flat, following an old road with several small creek crossings. After this, it becomes significantly steeper, rough, and root-ridden, with numerous switchbacks. You'll encounter sections where water flows down the path, making wooden stairs and puncheons slick. Obstacles like blowdowns and washed-out sections can also be present, sometimes requiring minor detours.
Beyond the challenging ascent, the trail leads to two beautiful alpine lakes. You'll first reach Little Greider Lake, a peaceful spot with attractive forest. About half a mile further is Big Greider Lake, set in a dramatic talus-lined bowl with Greider Peak towering above. Early in the hike, you'll also pass by Reflection Ponds, a marshy area known for its diverse insect and bird life.
Yes, as the trail is within the Sultan Basin Watershed, which supplies public drinking water, strict rules apply. This includes no swimming in the lakes and proper disposal of all waste. You are also required to register at the information kiosk before proceeding on the trail.
Yes, while primarily known as the Greider Lakes Trail, the route also passes through sections of the Boulder Lake Trail and the Greider/Boulder Lakes Trail, offering potential for extended exploration if you're prepared for longer distances.
The area is home to various wildlife, and sightings of black bears are possible. You might also spot different bird species and amphibians, especially around the marshy Reflection Ponds near the trailhead.
The most significant challenge is the steep, sustained ascent after the initial flat section. The path can be very rough, root-ridden, and slick, especially where water flows down it. Volunteers have carved steps in some steep areas to assist. Good quality hiking boots with ankle support and hiking poles are highly recommended for stability and to ease the strain on your knees during the descent. Be prepared for potential blowdowns or washed-out sections that might require minor scrambling.
While the initial two miles are relatively easy, the trail quickly becomes challenging with a significant and steep elevation gain over rough terrain. It's often described as a 'solid workout.' If you're a beginner, be prepared for a strenuous climb and ensure you have appropriate gear and fitness. It's not an ideal choice for those new to hiking steep, rugged trails.
