Alta / Peoria County, Illinois · Up to 4 miles return · Improved state rail-trail; historically crushed limestone
Start: Alta public trailhead at mile 0, North side of Alta Road near Alta Lane, Alta, IL. Follow IDNR directions from Allen Road through its left curve at Alta, then about 0.7 mile to the signed trail lot on the north side of Alta Road. Walk from designated lot spaces to the main trail. The Wyoming depot office is a separate arrival, not this start.
Ride: Follow the main state trail north toward Dunlap. Turn after two outward miles or before the first street, barrier or unsuitable loose tread, then retrace. Omit road / sidewalk sections within trail towns and the separate Peoria city continuation south of Alta.
Distance: Chosen four-mile maximum return from mile 0. Whole-trail 24.7 / 26-mile descriptions are broader scopes, not this outing.
Permission and effort: IDNR expressly permits bicycles on the improved main state trail. IDNR accessibility information rates the state trail easy; its activities page identifies a slight grade. Expect a gentle railway alignment rather than zero slope, and walk uncomfortable lot transitions.
Planning: Daylight within posted state-trail access. No ordinary trail or parking tariff established in reviewed sources; posted terms govern. Yield to people walking, announce passing and obey posted controls. No road detour is supplied.
Access reviewed October 20, 2026 Central (October 21 UTC): Current IDNR start and activities pages retain Alta public access. The prior October 16 region closure-table review had no Rock Island entry; a blank row is not field clearance. Stop for new barriers, debris, hunting-related local restrictions or unsuitable tread. The limestone composition is from historical manager-provided designation evidence; current IDNR describes an accessible easy trail without a new composition inspection. Require firm improved tread and turn before a soft or degraded section.
Bring water and choose suitable weather. Parking walking is extra. No surveyed parking-space pin or navigable GPX is supplied.
