Hennessey Meadows / Riordan Trailhead

Hennessey Meadows / Riordan Trailhead is a trail on public land, open to foot travel and the activities the terrain allows in Idaho, managed by USDA Forest Service.

Check the length, surface and elevation before you go and carry water — conditions change with the season.

On site and nearby you'll find Hiking.

The surrounding public land supports the usual mix of outdoor recreation.

Summer is the heart of the season here — warm days, long evenings and the fullest access — but also the busiest. Late spring and early fall are quieter and often more comfortable, and some access closes once winter sets in.

Hennessey Meadows / Riordan Trailhead is reached by public road; follow the site's posted directions for the final approach.

Check the weather and any closures before you go, carry water, and tell someone your plans. Cell service is often limited on public land — download maps in advance and be wildlife-aware where applicable.

Practice Leave No Trace: pack out all trash, stay on designated routes and roads, and respect posted rules, closures and fire restrictions — bans are common in dry summer months. Keep pets leashed where required and give wildlife room.

Go early on summer weekends to beat crowds and heat, bring layers and your own water, and double-check current conditions and seasonal access before you commit to the drive.
