A Mount Riga name is not a verified falls entrance
The historical route describes a winding dirt road, a pullout and a steep descent to Wachocastinook Creek. The saved state park match points to the Undermountain trailhead on a different approach. It does not confirm that creek pullout or a lawful water-entry route.
Resolve public roads and private boundaries
Mount Riga Incorporated states that its own lands and waterways are private and require permission, warning that GPS can direct people onto private roads. Apply those rules wherever the intended route enters its property; do not infer that every state trail or the entire creek is closed.
Beach permits and falls visits are separate
Ostrander is not Riga Falls
The owner advertises limited guest access at Ostrander Beach under its own permit and seasonal terms. Its published 2026 beach season ended September 7. That is a separate beach, not a falls swimming permit or evidence of a current opening at this creek.
Camping has its own restriction
The owner's site says its public campsites remain closed because of invasive-species concerns. That statement is scoped to its campsites, not a blanket trail or falls closure. Do not use an old no-camping field or another park campsite as permission for an overnight stay along this route.
Choose a confirmed approach or stay land-based elsewhere
The town's wetlands map provides watercourse context, not bathing permission. Confirm the exact entrance, lawful parking and allowed activity before travelling. No safe steep descent, jump depth, supervised pool or current water-quality result is established.
Getting There
The archived dirt-road mileage and steep descent are not verified present navigation. Confirm lawful approach and land boundaries before choosing a falls visit.

Access Notes
Do not substitute Undermountain trailhead for the historical pullout. Owner permission applies to its private property; exact route boundary unresolved.

Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.
