The N86Tralee to Dingle road (which is S2 throughout) begins at a roundabout junction with the N70 on the Tralee south-eastern bypass and follows the old route of the N70 along Castlemaine Road and then onto Dan Spring Road.
The route passes the Carlton Hotel, the Aqua Dome, and the former terminus of the now defunct narrow-gauge railway to Dingle, before heading out of town after junctions with the R551 (Prince's Street) and the R874 (Canal New Road), with the Blennerville windmill coming into view in the distance.
In less than 2 km, the N86 passes the famous old windmill that was the last sight of Ireland for the hundreds of thousands of emigrants that passed this way in the years following the Great Famine. The route then continues along the south coast of Tralee Bay to the small village of Camp, where it TOTSOs left at a junction with the R560, which runs to Dingle via Stradbally and the Conor Pass. Turning south, the N86 next crosses over the hills to Anascaul. It then runs west towards Lispole and Dingle.
