Frequently Asked Questions

How long does it typically take to hike the Lime Kiln Trail?

The full out-and-back hike is about 10.5 kilometers (6.5 miles) and generally takes around 3 hours to complete. This duration can vary depending on your pace and how much time you spend exploring the historical features.

What is the difficulty level and terrain like on this trail?

The Lime Kiln Trail is rated as easy to moderate. It follows an abandoned 1800s railway bed, offering relatively level sections. However, there's a gradual descent to the river and a corresponding climb on the return, with an elevation gain of about 157 meters (516 feet). The footing can be varied, from old road beds to narrower, stony paths, and can be muddy, especially after rain. You'll be hiking through a heavily forested, mossy canyon.

What historical features can I see along the way?

The trail is rich in history. The most prominent feature is the historic Lime Kiln on the Robe Canyon Historic Trail itself, a moss-covered stone structure from the 1890s. You can also spot remnants of the old Everett and Monte Cristo Railroad and logging operations, including old saw blades, bricks, and sections of steel rail. Interpretive signs provide context about the area's past.

Where can I park to access the Lime Kiln Trail?

The primary access point is the Lime Kiln Trailhead. Parking is available there, but it can fill up, especially on weekends. Arriving earlier in the day is recommended to secure a spot.

Are there any permits or fees required to hike in Robe Canyon Historic Park?

No, there are no specific permits or entrance fees required to hike the Lime Kiln Trail within Robe Canyon Historic Park. Parking is generally free at the trailhead.

Is the Lime Kiln Trail dog-friendly?

Yes, dogs are generally allowed on the Lime Kiln Trail. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all hikers.

What is the best time of year to hike this trail?

The trail is accessible year-round. Spring and fall offer lush greenery and cooler temperatures, making them ideal. Summer is also popular, but the canyon can provide a welcome respite from the heat. Winter hiking is possible, but be prepared for muddy conditions and potentially slick surfaces due to rain or ice.

Is this a loop trail or an out-and-back?

The main Lime Kiln Trail is an out-and-back route. You hike to the historic kiln and beyond, then return along the same path. While there are other paths in the area, the primary trail does not form a complete loop.

What kind of wildlife might I see along the trail?

The heavily forested canyon is home to various birds and small mammals. Keep an eye out for deer, squirrels, and a variety of bird species. The river itself may also offer glimpses of aquatic wildlife.

Does this trail connect with other paths?

Yes, the route also passes through sections of the Lime Kiln Trail River Loop and the Oz-Tom Bypass Trail, offering some variation for exploration within the park.

What should I wear and bring for a hike on this trail?

Given the potential for mud and varied terrain, sturdy hiking boots are recommended. Dress in layers, as the canyon can be cooler than surrounding areas. Bring water, snacks, and rain gear, especially during wetter seasons. A headlamp or flashlight can be useful if you plan to hike later in the day, as the dense forest can get dark quickly.
