Lillydale Lake is a 100+ ha regional recreation reserve in Lilydale (outer-east Melbourne, Yarra Valley/Yarra Ranges), built around a 28 ha artificial lake. The reserve is managed by Yarra Ranges Council and is a popular family destination — playground, off-lead dog areas, fishing jetty, picnic and BBQ shelters, ~10 km of shared paths and a non-powered boat launch. The MTB offering is a single dedicated skills trail (~1.1 km, blue / beginner) built and maintained by Yarra Ranges Mountain Bikers (YRMTB), opened around May 2017. It is one-way, sign-posted, and aimed at newcomers and kids practising fundamentals — berms, small jumps and rock gardens — before progressing to bigger Yarra Ranges networks at Warburton, Wesburn or Silvan.
This is not a destination MTB park: it's a "first ride" / family-stop park that pairs with the broader Lilydale outing. Riders typically combine the skills loop with a lap of the lake's shared paths and the playground/cafe stop. YRMTB is the same volunteer club that drives Warburton Bike Park, Wesburn Pump Track, Coldstream Pump Track and Silvan trails, so Lillydale Lake sits inside a much larger council-club partnership across the Yarra Ranges shire.
The lake itself is post-flood infrastructure — Melbourne Water built it in 1988–1990 after the 1984 floods on Olinda Creek, and the reserve was developed by the (then) Shire of Lillydale. The "Lillydale" double-L spelling is preserved from the old shire name; the surrounding suburb is "Lilydale" (single L).
Lillydale Lake reserve (1990): Following the September 1984 floods that hit Lilydale township, Melbourne Water and the (then) Shire of Lillydale jointly designed a flood-mitigation lake on Olinda Creek. Construction ran 1988–1990; the lake opened on 7 July 1990. The 28 ha lake (440 m dam wall, ~3 m average depth) sits on land formerly part of William Nicholson's Crown allotment 26, which had been used during the 19th-century Cave Hill limestone quarry era and was described pre-development as "a wasteland" of rubbish and abandoned cars. The reserve was hand-planted with thousands of trees by the council and community. Ruins of an 1850s flour mill (Cashin's mill) survive at the northern end of the dam wall. The "Lillydale" double-L spelling preserves the old shire name; the surrounding township is "Lilydale" (single L).
MTB skills trail (~2017): Yarra Ranges Mountain Bikers conceived, designed and supplied much of the labour for the beginner-friendly skills trail. The trail had opened by mid-May 2017 — Visit Yarra Valley and Dandenong Ranges promoted the opening on 11 May 2017 and YRMTB posted about the completed project on 16 May 2017. It is the council's first dedicated MTB feature at the lake and complements YRMTB's larger projects in Warburton, Wesburn and Silvan.
30-year milestone (2020): The reserve celebrated its 30th anniversary in 2020 with council communications, by which point it had become "the most popular project Council has ever done" (per quoted councillor) — multi-generational visitation and ongoing planting events.
Masterplan (2024): Yarra Ranges Council adopted a 15-year, ~$6.1 M masterplan on 9 April 2024 after April–June 2023 community consultation (385 contributors, 89% support). Plan focuses on accessibility, active-transport connections, additional parking and toilets, multi-sports area, fitness equipment, climbing space and shaded picnic areas. Driven partly by projected 43% population growth in the area to 2041 (incl. 8,000 new residents at neighbouring Kinley development).
