The Grand Sumorum Jeju: Which Pool Fits Your Stay?

The Grand Sumorum is at 118 Maksukpo-ro beside Jeju Olle Trail 7. Its pools differ by building and weather: the heated infinity pool is in the annex, the indoor pool is in the new building, and the Garden Pool is in the main building.

Match the pool to your arrival time

The Grand Infinity Pool is listed as a year-round heated pool. The hotel gives seasonal hours of 08:00–18:00 in winter and 08:00–20:00 in summer; weather and sunset can change them. Its adjoining jacuzzi operates 08:00–20:00. The hotel describes use as free for guests, but facility access can still be affected by onsite conditions.

The indoor pool runs 08:00–20:00 and has a regular closure on the first Monday of each month. The official notice also lists a dated maintenance closure for October 12–16, 2026. Check the live notice for later maintenance before relying on it as a weather fallback.

Location suits a coastal return

The official address is 118 Maksukpo-ro, Seogwipo. Jeju Olle Trail 7 passes by the hotel; the city centre and Jungmun are around a 15-minute drive according to the property’s directions. This is a coastal base, not a walk-to-everything downtown address, so decide how often you will leave and return before comparing rates.

For a late arrival, a pool closing before you return has no practical value for that night. Compare the room, view, breakfast and transport on their own, then count the facilities you can use on your actual dates.

Confirm the room and facility details together

Check the exact building and room category on the reservation page; the hotel has main-building and annex rooms. Before paying, confirm pool access, seasonal hours, the first-Monday closure, weather restrictions and any maintenance announcement for your dates.
