The best way to get to this cache is walking from Plaza Pelangi along Jl. Kuning, past the shaded rows of shopfronts.
In the Taman Pelangi kaleidoscope (Jalan Biru, Puteh, Ungu, Hijau, Nila, Kuning), the Jalan Kuning / Jalan Biru combination stands out for pedestrian appeal. The walk from Jl. Tebrau along Jl. Kuning is lined with attractively tended, pleasantly shaded and interestingly varied shopfronts. Jalan Biru starts from the intersection with Jl. Kuning which is lined with another cluster of attractive and varied shops and restaurants. The street's elevation provides some nice views and glimpses into the densifying JB city centre.
Suburban Johor Bahru doesn't generally have the density, walkability or traditions of suburban park usage, so this well-tended though dated park is usually empty. In fact, it's unusual to even come across a small suburban park. Taman Pelangi is also a high income area with lots of gated compounds probably not housing families with lots of young children looking for a place to play in a public park.
As well as a park, this small linear green area provides a street network combination for pedestrians to conveniently access Jl. Biru.
