Dalmaji-gil and Moontan Road share the Haeundae hillside but offer different walks: the road climbs past sea-facing viewpoints, while Moontan is a forest loop. Decide whether to return to the starting point or continue toward Cheongsapo before setting out.
The loop and its return
Visit Busan describes the Moontan Road loop as 2.2 km, taking about an hour at a leisurely pace. Lights operate from sunset to 23:00 and from 05:00 until sunrise, according to the current Dalmajigil and Moontan Road guide. The forest path connects with the wider coastal route; continuing toward Cheongsapo means the walk no longer returns to the same starting point.
The route is hilly. Wear shoes suitable for an incline and turn back at Haewoljeong if the group does not want the forest loop. The pavilion is a practical pause point, not a reason to complete the whole coastal line.
Getting to the start
For Dalmaji Road, take Metro Line 2 to Haeundae Station Exit 1 and transfer to village bus 2 or 10 toward Haewoljeong Pavilion; the official guide lists a five-minute walk from the stop. Buses 100, 139, 141, 200, 39 and 1003 stop near Mipo/Moontan Road, followed by a walk of about ten minutes. Use the official route details to choose the start that matches your plan.
Choose the finish before sunset
The route is free and listed as open at all times. That does not make every section equally easy after dark: pick the lit Moontan loop if you want a defined return, or set a bus stop, Cheongsapo or Songjeong as the finish if extending along the coast. Check the last transit from that endpoint before you leave Haeundae.
If Dalmaji is one stop in a larger Haeundae day, pair it with either the beach or Cheongsapo rather than trying to add every point along the ridge. The climb, crossings and photo stops determine the pace more than the map distance.
