A good question.
A local answer.

Check current guided tours or private transfers that include the nature reserve and a workable return time.

Compare the experience length and total family price with a standard zoo visit or another guided outing.

Choose one reserve walk that fits your time and fitness, then check current access, entry and weather conditions.

Book or arrange the return journey in advance because the sanctuary may be less convenient for an on-demand pickup after dark.

Check the current pedestrian map and path closures, then follow the lakeside route at an unhurried pace. The view can be part of the outing, not merely a transfer.

Drive carefully around dawn and dusk, when animals can be near roads. Do not stop abruptly in traffic for a photograph.

Choose a walk that matches your daylight and fitness, and carry water. If weather turns, keep a nearby museum or gallery as an easy backup rather than forcing the hike.

Choose a signed short walk from the current reserve map and check opening hours and weather. Tell someone your route and expected return, especially if you start early.

Check the reserve's current visitor information for transport and access before assuming a regular city bus reaches the entrance. A tour or private transfer may be more practical than several connections.
