Koyamaike Park

Start by the Information Plaza on the mainland, cross the bridge and follow the official Aoshima circuit signs. The Geopark leaflet includes the viewpoint, a view towards Fujishima and ishigama remains before returning. Its model course is about 3 km with 55 minutes of walking. Allow extra time for the climb, photographs and children’s pauses; shorten the outing if conditions or energy call for it.

Official model: about 55 minutes moving. Allow 75–120 minutes with stops; the longer allowance is editorial.

Begin at the Natural Garden’s northern side, explore its signed spaces at your own pace, then choose a lakeside seat. If you want to continue, use the official Oasis map to find the lawn and cherry-viewing square. This is a flexible sequence rather than a measured circuit. Turn back whenever you have had enough, leaving time to reach your car or bus.

Allow 60–90 minutes; editorial estimate.

Make Aoshima your first stop, take a picnic break, then transfer to Oasis Park for a contrasting garden visit. Keep the transfer separate from your walking allowance. The official leaflet shows a mainland connection, but it should not be mistaken for a verified barrier-free or traffic-free link. Using separate arrivals can make the day simpler for a group with mixed energy levels.

Allow a relaxed half-day including the transfer; editorial suggestion.

Give everyone a different subject: a leaf with an unusual edge, a reflection, a seed head or a stone pattern. Compare photographs over a snack rather than picking specimens. On Aoshima, make the bridge and one shore stop enough if younger children are tiring; completing a circuit is optional.

Aoshima has lawn and play facilities, but inspect the current equipment signs and choose what suits each child. Open water, cyclists and occasional management vehicles still require adult attention. Pick a picnic place away from the water’s edge and keep food packed when you are not eating.

The garden guide suggests watching quietly for a kingfisher near waterside planting. A glimpse is a possibility, not an appointment; stay on the path and do not approach a resting bird.

The garden’s interpretation mentions kites circling over the lake. Look up occasionally as well as across the water, and keep picnic food secure without feeding birds.

Agapanthus is one of the Natural Garden’s named summer flowers. Enjoy its shape from the path; the sources do not identify the particular species or cultivar planted.

Lotus at Fukui is a conservation planting in a freshwater viewing pond. The city gives July as a usual flowering period; check current conditions and respect protective barriers.

Crossing Aoshima Bridge gives the outing a clear beginning: pause where you can safely look back towards the mainland, then follow the island signs. The shore path and higher viewpoint offer different perspectives. The operator describes about 500 cherry trees of around 30 kinds, so spring interest comes in successive waves rather than one guaranteed peak day.

Tottori Hareyaka Garden was created under garden designer Paul Smither for the 2013 national urban greenery fair. Its naturalistic approach celebrates plant form and seasonal cycles, with more than 90% of its roughly 200 plant kinds described as Japanese native species. These are managed garden plantings. Look for the transition from fresh growth to flowers and seed, rather than expecting every bed to be at peak bloom.

The illustrated garden guide identifies a pergola, stone steps, a coastal garden, a grass garden and a deck beside the symbol tree. Let those details give your walk a rhythm: a wide lake view, a textured leaf, then the structure of a stone wall. Stay on the paths and use a bench when you want a longer look.

The Kanazawa and Fukui recreation areas suit an outing built around open space and the lake. Kanazawa has tennis courts and a multipurpose lawn; Fukui has the lotus-viewing pond. The Tsuzurao castle-site hill is another named feature of the western zone. Treat any hill exploration as an optional extra, checking the actual path and footing before committing.

Fukui’s lotus pond is especially interesting when read as a restoration project. The city explains that freshwater conditions were created after the lake became more saline in 2012; protected lotus plantings now grow there. July is the city’s usual flower-viewing guide, not a promise for your visit. Observe from the permitted viewing positions and respect any protective fencing.

The official Geopark walking leaflet explains how the lake developed from an inlet as coastal sand accumulated. It also introduces ishigama, stone arrangements associated with a traditional winter fishing method. Look for interpretation along the Aoshima course; water level and viewpoint affect what is visible. Do not enter the water or disturb the stones.

Aoshima’s early and late cherry varieties can extend interest from March into late April, depending on weather. At the Natural Garden, later spring brings a different palette, with the operator highlighting irises, rugosa roses and other flowers. Choose recent bloom information over a fixed annual date.

Agapanthus and other summer garden flowers give close-up subjects while the lake supplies a broad backdrop. Choose a shorter walk during heat, take regular shade breaks and carry enough water. The lotus pond is a possible July stop if the current growth warrants it.

The operator highlights several chrysanthemum relatives in the Natural Garden. Look at grasses and foliage as well as flowers, and try a low viewpoint from the path for layers against the lake. Sunset can be rewarding, but shorter days make return planning important.

The garden is deliberately cut back before heavy snow, so do not expect the full summer planting structure. The city describes winter as preparation for spring growth. A short waterside look can still be satisfying in suitable weather; avoid slippery, snowy or wind-exposed sections when footing is uncertain.

Ordinary garden and Aoshima visits are free. The Natural Garden has no regular closing day, but its adjacent northern parking lot operates 7:00–20:00 and vehicles cannot enter or leave outside that window. Other car parks and facilities have their own arrangements; check signs instead of extending those hours to the whole park.

Operator listings place toilets on Aoshima, beside the mainland management building, at the Natural Garden, and in the Kanazawa and Fukui areas. Shelters are also listed. The Information Plaza at the Aoshima entrance is listed as open 10:00–16:00, closed Wednesdays; confirm exceptional closures on 0857-31-2900. Bring picnic supplies rather than depending on a particular food outlet.

Ground golf is available in designated multipurpose spaces; bring your own equipment, and arrange group or exclusive use with the manager. Tennis is separately charged: the operator lists an adult rate of ¥400 per court per hour, plus ¥300 per hour for lighting. Check eligibility discounts, booking procedure and current fees before playing.

Aoshima’s multipurpose area offers free camping by advance application, with no same-day applications and no equipped kitchen. Overnight and day-use arrangements differ; check the operator’s current form and rules. Fire use is only for people with permission. The July 2026 notice warns that a fire mat alone may not protect grass: keep heat off the ground and take all charcoal and rubbish away.

A separately operated sightseeing boat departs from the Natural Garden. Its published autumn 2026 season runs on weekends from 17 October to 29 November, with reservations at least 3 days ahead and a minimum of 6 passengers. Adult fare is ¥1,500 and child fare ¥750; same-day cancellation is normally charged in full, with stated exceptions. Confirm operation and conditions directly before building your day around it.

Watch children closely at water, bridges and play facilities. Wear shoes that grip, shorten the outing in heat or strong wind, and obey closures and maintenance barriers. Do not treat a quiet water surface as an invitation to swim. Carry out litter, avoid feeding wildlife and give birds space to rest.

From JR Tottori Station, the operator gives about 20 minutes by car to Aoshima or Oasis Park and about 30 minutes to the western recreation zone, before traffic or parking delays. Search for the specific destination, not just the lake. Free parking is listed for the separate areas; capacity figures vary across official pages, so allow flexibility on busy days.

For Aoshima, use Hinomaru’s Yoshioka line to Aoshima Koen; direct trips from Tottori Station are roughly 20 minutes, while variants can take longer. For the garden, some Tottori University via Fuse services stop at Koen-mae (Koyamaike Natural Garden-mae), but others skip it. Toridai Fuzokuko is another tourism-listed option with about a 10-minute walk. Check the exact day, direction and return trip.

Do not rely on older references to the Loop Kirinjishi bus stopping at the Natural Garden. Its current published route does not serve Koyamaike. Use the regular-bus timetables or arrange a different transfer, and recheck notices before travel.

Designated accessible-parking spaces are listed for the principal areas. This does not establish a continuous accessible route: the garden guide includes stone steps and Aoshima has a hilltop viewpoint. Ask Tottori Green on 0857-28-5090 about surfaces, gradients, toilets and the exact entrance you intend to use. A short out-and-back can be a better fit than a full circuit.
