I love Sheeba Park. Spent happy 26 years walking in the park. The guards are very courteous, welcoming, even ask after you if they don't see you for a long period of time.
I'm giving it 3 stars because of some external to park reasons. First, it is now very noisy around the park, due to traffic. Second, also because of traffic it's air is full of fumes by evening. Thirdly, the huge LED sign in the crossing burns into my eyes if I walk there after daylight. So you see the Park itself is beautiful with a well laid trek, good parking area, but it is outside the park that makes it less desirable for me to go there. No, I cannot go there after Fajar. I'm sure the traffic noise and that horrid LED sign will not be a problem, but the air quality surely would be.
