Grand Hilai Sun Moon Lake — Private Onsen + Lake View in Every Room
Grand Hilai Sun Moon Lake (漢來日月行館) opened in February 2025 on the site of the former Sun Moon Resort, directly on the Shuishe shore of Sun Moon Lake. With every one of its 93 rooms offering a private bicarbonate hot-spring bath and an unobstructed lake view, positioned right beside Shuishe Pier and next door to The Lalu, it is the most compelling new luxury arrival at Sun Moon Lake — and the most serious challenger The Lalu has faced in years.
Sun Moon Lake is Taiwan's most celebrated inland destination, and for years the conversation about where to stay has begun and ended with The Lalu. Then, in February 2025, Grand Hilai Sun Moon Lake (漢來日月行館) opened on the same Shuishe shoreline — built on the footprint of the former Sun Moon Resort — and reframed that conversation entirely. The Grand Hilai Group, parent brand of the storied Grand Hi-Lai Hotel in Kaohsiung, committed to a single non-negotiable standard: every one of the 93 rooms would have a private bicarbonate hot-spring bath and a direct lake view. No standard rooms, no city-facing compromises.
"Opened the curtains to the lake, then slipped straight into the in-room onsen. There's nothing else to say — that experience is worth every dollar."
The defining feature is the sodium bicarbonate spring water piped directly into each room's soaking tub. Bicarbonate springs are among the mildest and most skin-friendly of Taiwan's hot-spring types — odourless, slightly alkaline, and praised for softening skin and easing muscle tension. Soaking in a private tub while looking out at the green-ringed lake at first light, or as the last glow fades behind the mountains, is the experience guests describe first and most emphatically when they write their reviews.
Location is the other ace card. The hotel sits directly adjacent to Shuishe Pier, the main departure point for lake cruises to Ita Thao Pier on the opposite bank, and to Xuanzang Temple further around the shoreline. Stepping from the hotel lobby to the boarding point takes under two minutes. The proximity to The Lalu — literally next door — means guests can compare both properties directly; what Grand Hilai offers is broadly equivalent lakefront access and a slightly more approachable starting price, with in-room hot-spring facilities that surpass what The Lalu provides at the same tier.
The floor-11 facilities elevate the stay further: an infinity-edge outdoor pool that merges visually with the lake horizon, plus gender-segregated indoor and outdoor public hot-spring pools for guests who want the communal onsen experience alongside the private tub in the room. The restaurant focuses on Taiwanese and Nantou regional cuisine, with freshwater specialities sourced locally — a genuine expression of place rather than generic hotel fare.
Guest rooms range from 50 to 360 sq m across Deluxe, Superior, and Suite categories. All are finished in a warm contemporary style — natural wood, stone textures, warm neutrals — that grounds the space in the landscape outside. Even the entry-level Deluxe rooms at 50 sq m feel genuinely spacious by urban hotel standards, and the soaking tub is positioned so the lake view is unimpeded from the water. Keeping total inventory to 93 rooms allows the hotel to maintain a staff-to-guest ratio that is reflected in the personalised, attentive service tone guests consistently praise.
The Grand Hilai Group's ownership connection to Fo Guang Shan Buddhist culture — the same heritage that underpins Grand Hi-Lai Hotel Kaohsiung — shapes the atmosphere in subtle but tangible ways. The service style is calm, orderly, and warm; the overall tone is restorative rather than flashy. Some travellers will find this perfectly aligned with the mindset that brings people to Sun Moon Lake in the first place. Others who prefer a more cosmopolitan luxury vibe may feel the environment is on the conservative side.
Honest trade-offs deserve clear mention. Grand Hilai opened in February 2025 — meaning the 218 Agoda reviews accumulated in the first three months are impressive in quality, but thin in volume compared with properties that have operated for a decade or more. Operational consistency over years remains to be demonstrated. Prices on weekends and public holidays rise sharply from the already-high weekday base; at peak periods the gap with The Lalu may narrow considerably. And with only 93 rooms, availability during Taiwan's Golden Week, Lunar New Year, or the Dragon Boat Festival window disappears quickly — sometimes months out.
The bottom line: for travellers whose Sun Moon Lake wish-list reads private in-room onsen + uninterrupted lake view + walking distance to the pier, Grand Hilai Sun Moon Lake delivers that combination more completely than any other property on the lake right now. It is the strongest challenger The Lalu has faced, and at a price point that is — for the moment — fractionally more accessible. If you are planning a trip to Nantou in 2025 or 2026 and this is the kind of stay you are after, it belongs at the top of your shortlist.

- 💡If a long track record of consistent reviews matters to you — Grand Hilai has only 218 Agoda reviews from its first 3 months of operation → The Lalu carries thousands of reviews over 20+ years of operation. If you rely on depth of review data, The Lalu is the lower-risk choice
- 💡If you are sensitive to brand identity linked to Buddhist culture — Grand Hilai Group has roots in Fo Guang Shan → the overall atmosphere is calm, orderly, and somewhat formal; this suits Sun Moon Lake's restorative character well, but may feel conservative to some travellers
- 💡If you are visiting on a holiday weekend or Golden Week — rates jump significantly and all 93 rooms sell out fast → book at least 1–2 months in advance, or target weekday stays for noticeably better value and availability
