Confirmed from Trail of Two Forests Interpretive Site's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

👟 good for all levels 2 mentions

“The hike is a smiple easy hike with alot of things to view and see.”

Lovely short trail and a boardwalk along the entire trail, highly interesting seeing all the lava formations along it, and if your daring enough there's a crawlspace, just bring a flashlight if you intend to do it

★★★★★ — Cole , May 2024

Nice quick walk. Very well maintained with elevated deck walk to avoid falling down lava tubes lol. You can walk off on a trail from the parking lot opposed to going on platform. The tubes were still wet from snow but passable if you dare enter the darkness 🤣

★★★★★ — Phil , Feb 2023

So amazing! It's a great short hike around a boardwalk. Just enough signage to explain what you're seeing. Our kids loved crawling through the lava tube (they have one open for you to explore). Worth the 20 minutes before or after doing Ape Caves.

★★★★★ — Rebecca , Jul 2022

A short trail with some great information. The crawl through tunnel is fun, and it's really great to see the smaller lava tunnels, and the growth on top of them! This would be great for kids and anyone else

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
