From the heart of Somerville, with its cafes, bakeries and shops, this relatively urban trail travels along the service road beside Frankston-Flinders Rd until it crosses Deanswood Drive and becomes a dedicated path. Through the small town of Tyabb with its antiques precinct, the path continues alongside Frankston-Flinders Rd. It runs parallel to the railway line eventually passing the Bluescope Steel Mill and finishing at Graydens Road at the northern end of Hastings.

This part of the trail is the first part of the Western Port Bay Trail that runs from Somerville to Balnarring.
From the Somerville Trail you can continue into, and through, Hastings along the Hastings Trail.
