Trail users can turn left, heading east toward the Belgrave Rail Trail, which initially runs on-road along Larissa Avenue and via Ringwood Lake. The Mullum Mullum Creek Trail takes an immediate right turn west towards Eastland Shopping Centre. A road crossing at Warrandyte Road and a tunnel under Ringwood Street sends you to the end of the EastLink Trail. Continuing under the EastLink onramps leads you under Deep Creek Road and into Yarran Dheran. The path continues north west past sensitive flora and fauna by the concrete path mixed with a series of timber bridges and boardwalks.
